HOW TO OBTAIN PERMIT COVERAGE UNDER THE CGP.
      To be covered under this permit, you must meet the eligibility conditions and follow the requirements for applying for permit coverage in this Part.  
ELIGIBILITY CONDITIONS REQIRED OF ALL PROJECTS.
      Only those projects that meet all of the following eligibility conditions may be covered under this permit:  
           You are an "operator" of the construction project for which discharges will be covered under this permit;
               Note:  	For the purposes of this permit, an "operator" is any party associated with a construction project that meets either of the following two criteria:
                       The party has operational control over construction plans and specifications, including the ability to make modifications to those plans and specifications; or
                       The party has day-to-day operational control of those activities at a project that are necessary to ensure compliance with the permit conditions (e.g., they are authorized to direct workers at a site to carry out activities required by the permit).
                     Subcontractors generally are not considered operators for the purposes of this permit.
                Note:  	Where there are multiple operators associated with the same project, all operators are required to obtain permit coverage.  The following applies in these situations:
                       1.                        If one operator has control over plans and specifications and a different operator has control over activities at the project site, they may divide responsibility for compliance with the terms of this permit as long as they develop a group SWPPP (see Part 7.1.1), which documents which operator has responsibility for each requirement of the permit. 
                       2.                        If an operator only has operational control over a portion of a larger project (e.g., one of four homebuilders in a subdivision), the operator is responsible for compliance with all applicable effluent limits, terms, and conditions of this permit as it relates to the activities on their portion of the construction site, including protection of endangered species, critical habitat, and historic properties, and implementation of control measures described in the SWPPP in the areas under their control. 
                       3.                        You must ensure either directly or through coordination with other permittees, that your activities do not render another party's pollutant discharge controls ineffective. 
                       4.                        If the operator of a "construction support activity" (see Part 1.3.c) is different than the operator of the main construction site, that operator is also required to obtain permit coverage.
           Your project:
              Will disturb 1 or more acres of land, or will disturb less than 1 acre of land but is part of a common plan of development or sale that will ultimately disturb 1 or more acres of land; or 
              Your project's discharges have been designated by EPA as needing a permit under § 122.26(a)(1)(v) or § 122.26(b)(15)(ii);
           Your project is located in an area where EPA is the permitting authority (see Appendix B);
           Discharges from your project are not:
              Already covered by a different NPDES permit for the same discharge; or
              In the process of having coverage under a different NPDES permit for the same discharge denied, terminated, or revoked.[,] 
           You are able to demonstrate that you meet one of the criteria listed in Appendix D with respect to the protection of species that are federally-listed as endangered or threatened under the Endangered Species Act (ESA) or federally-designated critical habitat; 
           You have completed the screening process in Appendix E relating to the protection of historic properties and places; and
           You have complied with all requirements in Part 9 imposed by the applicable state, Indian tribe, or territory in which your construction activities will occur. 
ELIGIBILITY CONDITIONS THAT APPLY DEPENDING ON TYPE OF PROJECT.
You must also satisfy, if applicable, the conditions in Parts 1.2.1 through 1.2.4 in order to obtain coverage under this permit.
Eligibility for Emergency-Related Construction Activities.
If you are conducting earth-disturbing activities in response to a public emergency (e.g., natural disaster, widespread disruption in essential public services), and the related work requires immediate authorization to avoid imminent endangerment to human health, public safety, or the environment, or to reestablish essential public services, you are authorized to discharge on the condition that a complete and accurate NOI is submitted within 30 calendar days after commencing earth-disturbing activities (see Table 1) establishing that you are eligible under this permit.  You are also required to provide documentation in your SWPPP to substantiate the occurrence of the public emergency.
Water Quality Standards  -  Eligibility for New Sources.
      If you are a "new source" (as defined in Appendix A), you are not eligible for coverage under this permit for discharges that EPA, prior to authorization under this permit, determines will cause, have the reasonable potential to cause, or contribute to an excursion above any applicable water quality standard.  Where such a determination is made prior to authorization, EPA may notify you that an individual permit application is necessary in accordance with Part 1.4.5. However, EPA may authorize your coverage under this permit after you have included appropriate controls and implementation procedures designed to bring your discharge into compliance with water quality standards.  In the absence of information demonstrating otherwise, EPA expects that compliance with the stormwater control requirements of this permit, including the requirements applicable to such discharges in Part 3.2, will result in discharges that will not cause, have the reasonable potential to cause, or contribute to an excursion above any applicable water quality standard.  
Discharging to Waters with High Water Quality  -  Eligibility for New Sources.
If you are a "new source" (as defined in Appendix A), you are eligible to discharge to a Tier 2, Tier 2.5, or Tier 3 water only if your discharge will not lower the water quality of the applicable water.  In the absence of information demonstrating otherwise, EPA expects that compliance with the stormwater control requirements of this permit, including the requirements applicable to such discharges in Part 3.3.2, will result in discharges that will not lower the water quality of the applicable water.  See list of Tier 2, Tier 2.5, and Tier 3 waters in Appendix F.
         Note:  	Your project will be considered to discharge to a Tier 2, Tier 2.5, or Tier 3 water if the first surface water to which you discharge is identified by a state, tribe, or EPA as a Tier 2, Tier 2.5, or Tier 3 water.  For discharges that enter a storm sewer system prior to discharge, the first surface water to which you discharge is the waterbody that receives the stormwater discharge from the storm sewer system.
Use of Cationic Treatment Chemicals.
      If you plan to use cationic treatment chemicals (as defined in Appendix A), you are ineligible for coverage under this permit, unless you notify your applicable EPA Regional Office in advance and the EPA office authorizes coverage under this permit after you have included appropriate controls and implementation procedures designed to ensure that your use of cationic treatment chemicals will not lead to a violation of water quality standards. 
 Types of Discharges Authorized Under the CGP.
The following is a list of discharges that are allowed under the permit provided that appropriate stormwater controls are designed, installed, and maintained:
           Stormwater discharges, including stormwater runoff, snowmelt runoff, and surface runoff and drainage, associated with construction activity under 40 CFR § 122.26(b)(14) or § 122.26(b)(15)(i);
           Stormwater discharges designated by EPA as needing a permit under 40 CFR § 122.26(a)(1)(v) or § 122.26(b)(15)(ii);
           Stormwater discharges from construction support activities (e.g., concrete or asphalt batch plants, equipment staging yards, material storage areas, excavated material disposal areas, borrow areas) provided:
              The support activity is directly related to the construction site required to have permit coverage for stormwater discharges;
              The support activity is not a commercial operation, nor does it serve multiple unrelated construction projects; 
              The support activity does not continue to operate beyond the completion of the construction activity at the project it supports; and
              Stormwater controls are implemented in accordance with Part 2 and, if applicable, Part 3, for discharges from the support activity areas.
          The following non-stormwater discharges from your construction activity, provided that, with the exception of water used to control dust and to irrigate areas to be vegetatively stabilized, these discharges are not routed to areas of exposed soil on your site and you comply with any applicable requirements for these discharges in Part 2:
              Discharges from emergency fire-fighting activities;
              Fire hydrant flushings;
              Landscape irrigation;
              Water used to wash vehicles and equipment, provided that there is no discharge of soaps, solvents, or detergents used for such purposes;
              Water used to control dust;
              Potable water including uncontaminated water line flushings;
              Routine external building washdown that does not use detergents;
              Pavement wash waters provided spills or leaks of toxic or hazardous materials have not occurred (unless all spill material has been removed) and where detergents are not used. You are prohibited from directing pavement wash waters directly into any surface water, storm drain inlet, or stormwater conveyance, unless the conveyance is connected to a sediment basin, sediment trap, or similarly effective control;
              Uncontaminated air conditioning or compressor condensate;
              Uncontaminated, non-turbid discharges of ground water or spring water;
              Foundation or footing drains where flows are not contaminated with process materials such as solvents or contaminated ground water; and
              Construction dewatering water that has been treated by an appropriate control under Part 2.1.3.4; and
           Discharges of stormwater listed above in Parts a, b, and c, or authorized non-stormwater discharges in Part d above, commingled with a discharge authorized by a different NPDES permit and/or a discharge that does not require NPDES permit authorization.
 SUBMITTING YOUR NOTICE OF INTENT (NOI).
      To be covered under this permit, you must submit to EPA a complete and accurate NOI prior to commencing construction activities.  The NOI certifies to EPA that you are eligible for coverage according to Part 1.1 and 1.2, and provides information on your construction operation and discharge.  
         Note: 	 All "operators" (as defined in Appendix A) associated with your construction project, who meet the Part 1.1 eligibility requirements, and who elect to seek coverage under this permit, are required to submit an NOI.
         Note:  	There are two exceptions to the requirement to submit the NOI prior to the commencement of construction activities:  (1) for emergency-related projects, and (2) for new projects scheduled to commence construction activities on or after February 16, 2012, but no later than March 1, 2012.  For these two types of projects, the NOI must be submitted within 30 calendar days after the commencement of earth-disturbing activities (see Part 1.4.2). 
         Note:  	You must complete the development of a Stormwater Pollution Prevention Plan (SWPPP) consistent with Part 7 prior to submitting your NOI for coverage under this permit. 
 How to Submit Your NOI.
You are required to use EPA's electronic NOI system, or "eNOI system", to prepare and submit your NOI.  Go to www.epa.gov/npdes/stormwater/cgpenoi to access the eNOI system and file an NOI.  If you have a problem with the use of the eNOI system, contact the EPA Regional Office that corresponds to the location of your site.  If you are given approval by the EPA Regional Office to use a paper NOI, and you elect to use it, you must complete the form in Appendix J.
 Deadlines for Submitting Your NOI and Your Official Date of Permit Coverage.
Table 1 provides the deadlines for submitting your NOI and your official start date of permit coverage, which differ depending on when you commence construction activities.  The following terms are used in Table 1 to establish NOI deadlines:
           New project  -  a construction project that commences construction activities on or after February 16, 2012.
           Existing project  -  a construction project that commenced construction activities prior to February 16, 2012.  
           New operator of a new or existing project  -  an operator that through transfer of ownership and/or operation replaces the operator of an already permitted construction project.

You are considered covered under this permit 14 calendar days after EPA has acknowledged receipt of your NOI on the Agency's website (www.epa.gov/npdes/stormwater/cgpnoisearch), unless EPA notifies you that your authorization has been delayed or denied.
       Note:  	If you have missed the deadline to submit your NOI, any and all discharges from your construction activities will continue to be unauthorized under the Clean Water Act until they are covered by this or a different NPDES permit.  EPA may take enforcement action for any unpermitted discharges that occur between the commencement of earth-disturbing activities and discharge authorization.
      Note: 	Discharges are not authorized if your NOI is incomplete or inaccurate or if you were never eligible for permit coverage.
 Your Official End Date of Permit Coverage
  Once covered under this permit, your coverage will last until the date that:
            You terminate permit coverage consistent with Part 8; or
            Your discharges are permitted under a different NPDES permit or a reissued or replacement version of this permit after expiring on February 16, 2017; or 
            For existing projects that continue after this permit has expired, the deadline has passed for the submission of an NOI for coverage under a reissued or replacement version of this permit and you have failed to submit an NOI by the required deadline. 
 Continuation of Coverage for Existing Permittees After the Permit Expires.
If this permit is not reissued or replaced prior to the expiration date, it will be administratively continued in accordance with the Administrative Procedure Act and remain in force and effect for discharges that were covered prior to expiration.  If you were granted permit coverage prior to the expiration date, you will automatically remain covered by this permit until the earliest of:
            Your authorization for coverage under a reissued or replacement version of this permit following your timely submittal of a complete and accurate NOI requesting coverage under the new permit; or
                Note:  	If you fail to submit a timely NOI for coverage under the reissued or replacement permit, your coverage will terminate on the date that the NOI was due.
            Your submittal of a Notice of Termination; or
            Issuance or denial of an individual permit for the project's discharges; or
            A final permit decision by EPA not to reissue a general permit, at which time EPA will identify a reasonable time period for covered dischargers to seek coverage under an alternative general permit or an individual permit.  Coverage under this permit will terminate at the end of this time period.
EPA reserves the right to modify or revoke and reissue this permit under 40 CFR 122.62 and 63, in which case you will be notified of any relevant changes or procedures to which you may be subject.
 Procedures for Denial of Coverage.
Following your submittal of a complete and accurate NOI, you may be notified in writing by EPA that you are not covered, and that you must either apply for and/or obtain coverage under an individual NPDES permit or an alternate general NPDES permit.  This notification will include a brief statement of the reasons for this decision and will provide application information.  Any interested person may request that EPA consider requiring an individual permit under this paragraph.  
If you are already a permittee with coverage under this permit, the notice will set a deadline to file the permit application, and will include a statement that on the effective date of the individual NPDES permit or alternate general NPDES permit, as it applies to you, coverage under this general permit will terminate.  EPA may grant additional time to submit the application if you request it.  If you are covered under this permit and fail to submit an individual NPDES permit application or an NOI for an alternate general NPDES permit as required by EPA, then the applicability of this permit to you is terminated at the end of the day specified by EPA as the deadline for application submittal.  EPA may take appropriate enforcement action for any unpermitted discharge.  If you submit a timely permit application, then when an individual NPDES permit is issued to you or you are provided with coverage under an alternate general NPDES permit, your coverage under this permit is terminated on the effective date of the individual permit or date of coverage under the alternate general permit.
 REQUIREMENT TO POST A NOTICE OF YOUR PERMIT COVERAGE.
      You must post a sign or other notice conspicuously at a safe, publicly accessible location in close proximity to the project site.  At a minimum, the notice must include the NPDES Permit tracking number and a contact name and phone number for obtaining additional project information.  The notice must be located so that it is visible from the public road that is nearest to the active part of the construction site, and it must use a font large enough to be readily viewed from a public right-of-way.
EFFLUENT LIMITATIONS APPLICABLE TO ALL DISCHARGES FROM CONSTRUCTION SITES
      You are required to comply with the following effluent limitations in this Part for discharges from your site and/or from construction support activities (see Part 1.3.c).   
         Note:  	If your project is an "existing project" (see Part 1.4.2.b) or if you are a "new operator of an existing project" (see Part 1.4.2.c), and it is infeasible for you to comply with a specific requirement in this Part because (1) the requirement was not part of the permit you were previously covered under (i.e., the 2003 or 2008 CGP), and (2) because you are prevented from compliance due to the nature or location of earth disturbances that commenced prior to February 16, 2012, or  because you are unable to comply with the requirement due to the manner in which stormwater controls have already been installed or were already designed prior to February 16, 2012, you are required to document this fact in your SWPPP and are waived from complying with that requirement. This flexibility applies only to the requirements in Parts 2.1, and 2.3.3 through 2.3.5 (except for Parts 2.3.3.1, 2.3.3.2b, 2.3.3.3c.i, and 2.3.3.4).   This only applies to those portions of your site that have already commenced earth-disturbing activities or where stormwater controls implemented in compliance with the previous permit have already been installed.
      Part 2 includes the following types of requirements:
            Erosion and Sediment Control Requirements (Part 2.1)
            Stabilization Requirements (Part 2.2)
            Pollution Prevention Requirements (Part 2.3)
             
EROSION AND SEDIMENT CONTROL REQUIREMENTS. 
      YOU MUST DESIGN, INSTALL, AND MAINTAIN EROSION AND SEDIMENT CONTROLS THAT MINIMIZE the discharge of pollutants from earth-disturbing activities.  To meet this requirement, you must comply with the following provisions.  
General Requirements Applicable to All Construction Sites.
Area of Disturbance.  You are required to minimize the amount of soil exposed during construction activities.  You are also subject to the deadlines for temporarily and/or permanently stabilizing exposed portions of your site pursuant to Part 2.2.
Design Requirements.  
You must account for the following factors in designing your stormwater controls:
The expected amount, frequency, intensity, and duration of precipitation;
The nature of stormwater runoff and run-on at the site, including factors such as expected flow from impervious surfaces, slopes, and site drainage features.  If any stormwater flow will be channelized at your site, you must design stormwater controls to control both peak flowrates and total stormwater volume to minimize erosion at outlets and to minimize downstream channel and streambank erosion; and
The range of soil particle sizes expected to be present on the site.  
                You must direct discharges from your stormwater controls to vegetated areas of your site to increase sediment removal and maximize stormwater infiltration, including any natural buffers established under Part 2.1.2.1, unless infeasible.  Use velocity dissipation devices if necessary to prevent erosion when directing stormwater to vegetated areas. 
Installation Requirements.  
                 Complete installation of stormwater controls by the time each phase of earth-disturbance has begun, unless infeasible.  By the time earth-disturbing activities in any given portion of your site have begun, unless infeasible, you must install and make operational any downgradient sediment controls (e.g., buffers or equivalent sediment controls, perimeter controls, exit point controls, storm drain inlet protection) that control discharges from the initial site clearing, grading, excavating, and other land-disturbing activities.  
                    Note:  	Where it is infeasible to install stormwater controls prior to the initial earth disturbance, it is EPA's expectation that it will be a rare circumstance that will prevent the operator from installing such controls immediately following the initial earth disturbance.
                  Following the installation of these initial controls, all other stormwater controls planned for this portion of your site and described in your SWPPP must be installed and made operational as soon as conditions on the site allow.
                     Note:  	The requirement to install stormwater controls prior to earth-disturbance for each phase of the project does not apply to the earth disturbance associated with the actual installation of these controls.
                Use good engineering practices and follow manufacturer's specifications.  You must install all stormwater controls in accordance with good engineering practices, including applicable design specifications.
                     Note:  	Design specifications may be found in manufacturer specifications and/or in applicable erosion and sediment control manuals or ordinances. Any departures from such specifications must reflect good engineering practice and must be explained in your SWPPP.
Maintenance Requirements.  
You must ensure that all erosion and sediment controls required in this Part remain in effective operating condition during permit coverage and are protected from activities that would reduce their effectiveness.  
You must inspect all erosion and sediment controls in accordance with the applicable requirements in Part 4.1, and document your findings in accordance with Part 4.1.7.  If you find a problem (e.g., erosion and sediment controls need to be replaced, repaired, or maintained), you must make the necessary repairs or modifications in accordance with the following schedule:
Initiate work to fix the problem immediately after discovering the problem, and complete such work by the close of the next work day, if the problem does not require significant repair or replacement, or if the problem can be corrected through routine maintenance.
When installation of a new erosion or sediment control or a significant repair is needed, you must install the new or modified control and make it operational, or complete the repair, by no later than 7 calendar days from the time of discovery where feasible.  If it is infeasible to complete the installation or repair within 7 calendar days, you must document in your records why it is infeasible to complete the installation or repair within the 7-day timeframe and document your schedule for installing the stormwater control(s) and making it operational as soon as practicable after the 7-day timeframe.  Where these actions result in changes to any of the stormwater controls or procedures documented in your SWPPP, you must modify your SWPPP accordingly within 7 calendar days of completing this work. 
Erosion and Sediment Control Requirements Applicable to All Sites.
Provide Natural Buffers or Equivalent Sediment Controls. (These requirements only apply when a surface water is located within 50 feet of your project's earth disturbances).  
                  Note:  	EPA does not consider stormwater control features (e.g., stormwater conveyance channels, storm drain inlets, sediment basins) to constitute "surface waters" for the purposes of triggering the requirement to comply with this Part.
                  Note:	Areas that you do not own or that are otherwise outside your operational control may be considered areas of undisturbed natural buffer for purposes of compliance with this part.
               You must ensure that any discharges to surface waters through the area between the disturbed portions of the property and any surface waters located within 50 feet of your site are treated by an area of undisturbed natural buffer and/or additional erosion and sediment controls in order to achieve a reduction in sediment load equivalent to that achieved by a 50-foot natural buffer.  Refer to Appendix G (Buffer Guidance) for information to assist you in complying with this requirement, and to Part 2.1.2.1e for exceptions to this requirement.
Compliance Alternatives.  You can comply with this requirement in one of the following ways:
Provide and maintain a 50-foot undisturbed natural buffer; or
                            Note:  	If your earth disturbances are located 50 feet or further from a surface water, then you have complied with this alternative.
Provide and maintain an undisturbed natural buffer that is less than 50 feet and is supplemented by additional erosion and sediment controls, which in combination achieves the sediment load reduction equivalent to a 50-foot undisturbed natural buffer; or
If it is infeasible to provide and maintain an undisturbed natural buffer of any size, you must implement erosion and sediment controls that achieve the sediment load reduction equivalent to a 50-foot undisturbed natural buffer.  
                            Note:  	For the compliance alternatives in Parts 2.1.2.1a.i and 2.1.2.1a.ii, you are not required to enhance the quality of the vegetation that already exists in the buffer, or provide vegetation if none exists (e.g., arid and semi-arid areas).  You only need to retain and protect from disturbance the natural buffer that existed prior to the commencement of construction.  Any preexisting structures or impervious surfaces are allowed in the natural buffer provided you retain and protect from disturbance the natural buffer area outside the preexisting disturbance.  Similarly, for alternatives 2.1.2.1a.ii and 2.1.2.1a.iii, you are required to implement and maintain sediment controls that achieve the sediment load reduction equivalent to the undisturbed natural buffer that existed on the site prior to the commencement of construction.  In determining equivalent sediment load reductions, you may consider naturally non-vegetated areas and prior disturbances.  See Appendix G for a discussion of how to determine equivalent reductions.
                    You must document the compliance alternative you have selected in your SWPPP, and comply with the applicable additional requirements described in Parts 2.1.2.1b and 2.1.2.1c below.
                    The compliance alternative selected above must be maintained throughout the duration of permit coverage, except that you may select a different compliance alternative during your period of permit coverage, in which case you must modify your SWPPP to reflect this change. 
Additional Requirements for the Compliance Alternatives in Parts 2.1.2.1a.i and 2.1.2.1a.ii.  If you choose either of the compliance alternatives in Parts 2.1.2.1a.i or 2.1.2.1a.ii above, throughout your period of coverage under this permit, you must comply with the following additional requirements:
Ensure that all discharges from the area of earth disturbance to the natural buffer are first treated by the site's erosion and sediment controls, and use velocity dissipation devices if necessary to prevent erosion caused by stormwater within the buffer; 
Document in your SWPPP the natural buffer width retained on the property, and show the buffer boundary on your site plan; and
Delineate, and clearly mark off, with flags, tape, or other similar marking device all natural buffer areas.
Additional Requirements for the Compliance Alternatives in Parts 2.1.2.1a.ii and 2.1.2.1a.iii.  If you choose either of the compliance alternatives in Parts 2.1.2.1a.ii and 2.1.2.1a.iii, you must document in your SWPPP the erosion and sediment control(s) you will use to achieve an equivalent sediment reduction, and any information you relied upon to demonstrate the equivalency.
Additional Requirement for the Compliance Alternative in Part 2.1.2.1a.iii.  If you choose the compliance alternative in Part 2.1.2.1a.iii, you must also include in your SWPPP a description of why it is infeasible for you to provide and maintain an undisturbed natural buffer of any size.
Exceptions. 
If there is no discharge of stormwater to surface waters through the area between your site and any surface waters located within 50 feet of your site, you are not required to comply with the requirements in this Part. This includes situations where you have implemented control measures, such as a berm or other barrier, that will prevent such discharges.
Where no natural buffer exists due to preexisting development disturbances (e.g., structures, impervious surfaces) that occurred prior to the initiation of planning for the current development of the site, you are not required to comply with the requirements in this Part, unless you will remove portions of the preexisting development. 
                        Where some natural buffer exists but portions of the area within 50 feet of the surface water are occupied by preexisting development disturbances, you are required to comply with the requirements in this Part.  For the purposes of calculating the sediment load reduction for either Part 2.1.2.1a.ii or 2.1.2.1a.iii above, you are not expected to compensate for the reduction in buffer function from the area covered by these preexisting disturbances.  See Appendix G for further information on how to comply with the compliance alternatives in Part 2.1.2.1a.ii or 2.1.2.1a.iii above.
                        If during your project, you will disturb any portion of these preexisting disturbances, the area disturbed will be deducted from the area treated as natural buffer. 
                   i. 
                   ii. 
For "linear construction projects" (see Appendix A), you are not required to comply with the requirements in this Part if site constraints (e.g., limited right-of-way) prevent you from meeting any of the compliance alternatives in Part 2.1.2.1a, provided that, to the extent practicable, you limit disturbances within 50 feet of the surface water and/or you provide supplemental erosion and sediment controls to treat stormwater discharges from earth disturbances within 50 feet of the surface water.  You must also document in your SWPPP your rationale as to why it is infeasible for you to comply with the requirements in Part 2.1.2.1a, and describe any buffer width retained and/or supplemental erosion and sediment controls installed. 
For "small residential lot" construction (i.e., a lot being developed for residential purposes that will disturb less than 1 acre of land, but is part of a larger residential project that will ultimately disturb greater than or equal to 1 acre), you have the option of complying with the requirements in Appendix G (Part G.2.3).
The following disturbances within 50 feet of a surface water are exempt from the requirements in this Part:
               *                              Construction approved  under a CWA Section 404 permit; or
               *                              Construction of a water-dependent structure or water access area (e.g., pier, boat ramp, trail). 
                        You must document in your SWPPP if any of the above disturbances will occur within the buffer area on your site. 
Install Perimeter Controls.  
Installation Requirements: You must install sediment controls along those perimeter areas of your site that will receive stormwater from earth-disturbing activities.  
                    For linear projects with rights-of-way that restrict or prevent the use of such perimeter controls, you must maximize the use of these controls where practicable and document in your SWPPP why it is impracticable in other areas of the project. 
Maintenance Requirements: You must remove sediment before it has accumulated to one-half of the above-ground height of any perimeter control.  
Minimize Sediment Track-Out.  You must minimize the track-out of sediment onto off-site streets, other paved areas, and sidewalks from vehicles exiting your construction site.  To comply with this requirement, you must:
Restrict vehicle use to properly designated exit points; 
Use appropriate stabilization techniques at all points that exit onto paved roads so that sediment removal occurs prior to vehicle exit; 
Where necessary, use additional controls to remove sediment from vehicle tires prior to exit; and
Where sediment has been tracked-out from your site onto the surface of off-site streets, other paved areas, and sidewalks, you must remove the deposited sediment by the end of the same work day in which the track-out occurs or by the end of the next work day if track-out occurs on a non-work day. You must remove the track-out by sweeping, shoveling, or vacuuming these surfaces, or by using other similarly effective means of sediment removal. You are prohibited from hosing or sweeping tracked-out sediment into any stormwater conveyance (unless it is connected to a sediment basin, sediment trap, or similarly effective control), storm drain inlet, or surface water.
                       Note:  EPA recognizes that some fine grains may remain visible on the surfaces of off-site streets, other paved areas, and sidewalks even after you have implemented sediment removal practices.  Such "staining" is not a violation of Part 2.1.2.3. 
Control Discharges from Stockpiled Sediment or Soil.  For any stockpiles or land clearing debris composed, in whole or in part, of sediment or soil, you must comply with the following requirements:
                 Note: 	For the purposes of this permit, sediment or soil stockpiles are defined as the storage for multiple days of soil or other sediment material to be used in the construction project.
Locate the piles outside of any natural buffers established under Part 2.1.2.1a and physically separated from other stormwater controls implemented in accordance with Part 2.1;
Protect from contact with stormwater (including run-on) using a temporary perimeter sediment barrier;
Where practicable, provide cover or appropriate temporary stabilization to avoid direct contact with precipitation or to minimize sediment discharge;
Do not hose down or sweep soil or sediment accumulated on pavement or other impervious surfaces into any stormwater conveyance (unless connected to a sediment basin, sediment trap, or similarly effective control), storm drain inlet, or surface water; and
Unless infeasible, contain and securely protect from wind.
Minimize Dust.  In order to avoid pollutants from being discharged into surface waters, to the extent feasible, you must minimize the generation of dust through the appropriate application of water or other dust suppression techniques.
Minimize the Disturbance of Steep Slopes.  You must minimize the disturbance of "steep slopes" (see definition in Appendix A).  
                 Note:  The permit does not prevent or prohibit disturbance on steep slopes.  For some projects, disturbance on steep slopes may be necessary for construction (e.g., a road cut in mountainous terrain).  If a disturbance to steep slopes is required for the project, EPA would recognize that it is not economically achievable to avoid the disturbance to steep slopes. However, in cases where steep slope disturbances are required, minimizing the disturbances to steep slopes consistent with this requirement can be accomplished through the implementation of a number of standard erosion and sediment control practices, such as by phasing disturbances to these areas and using stabilization practices designed to be used on steep grades.
Preserve Topsoil.  You must preserve native topsoil on your site, unless infeasible.  
                 Note:  	Some projects may be designed to be highly impervious after construction, and therefore little or no vegetation is intended to remain.  In these cases, preserving topsoil at the site would not be feasible.  Some sites may not have space to stockpile topsoil on site for later use, in which case, it may also not be feasible to preserve topsoil. 
                 Note: 	Stockpiling of topsoil at off-site locations, or transfer of topsoil to other locations, is an example of a practice that is consistent with the requirements in this Part.
Minimize Soil Compaction.  In areas of your site where final vegetative stabilization will occur or where infiltration practices will be installed, you must either:
Restrict vehicle / equipment use.  Restrict vehicle and equipment use in these locations to avoid soil compaction; or
Use soil conditioning techniques.  Prior to seeding or planting areas of exposed soil that have been compacted, use techniques that condition the soils to support vegetative growth, if necessary and feasible.  
Protect Storm Drain Inlets.  If you discharge to any storm drain inlet that carries stormwater flow from your site directly to a surface water (and it is not first directed to a sediment basin, sediment trap, or similarly effective control), and you have authority to access the storm drain inlet, you must:
Installation Requirements.  Install inlet protection measures that remove sediment from your discharge prior to entry into the storm drain inlet. 
                       Note: 	Inlet protection measures can be removed in the event of flood conditions or to prevent erosion.
Maintenance Requirements.  Clean, or remove and replace, the protection measures as sediment accumulates, the filter becomes clogged, and/or performance is compromised.  Where there is evidence of sediment accumulation adjacent to the inlet protection measure, you must remove the deposited sediment by the end of the same work day in which it is found or by the end of the following work day if removal by the same work day is not feasible.
Requirements Applicable Only to Sites Using These Specific Stormwater Controls.
You are required to comply with the following requirements if you will install any of the following stormwater controls at your site:
Constructed Stormwater Conveyance Channels. Design stormwater conveyance channels to avoid unstabilized areas on the site and to reduce erosion, unless infeasible.  Minimize erosion of channels and their embankments, outlets, adjacent streambanks, slopes, and downstream waters during discharge conditions through the use of erosion controls and velocity dissipation devices within and along the length of any constructed stormwater conveyance channel, and at any outlet to provide a non-erosive flow velocity.
Sediment Basins.  If you install a sediment basin , you must comply with the following:
Design requirements.  
Provide storage for either (1) the calculated volume of runoff from a 2-year, 24-hour storm (see Appendix H), or (2) 3,600 cubic feet per acre drained; 
When discharging from the sediment basin, utilize outlet structures that withdraw water from the surface in order to minimize the discharge of pollutants, unless infeasible;
                           Note:  	EPA believes that the circumstances in which it is infeasible to design outlet structures in this manner are rare.  Exceptions may include areas with extended cold weather, where surface outlets may not be feasible during certain time periods (although it is expected that they would be used during other periods).  If you have determined that it is infeasible to meet this requirement, you must provide documentation in your SWPPP to support your determination.
Prevent erosion of (1) the sediment basin using stabilization controls (e.g., erosion control blankets), and (2) the inlet and outlet using erosion controls and velocity dissipation devices; and 
Sediment basins must be situated outside of surface waters and any natural buffers established under Part 2.1.2.1a, and must be designed to avoid collecting water from wetlands.
Maintenance requirements.  Keep in effective operating condition and remove accumulated sediment to maintain at least (1/2) of the design capacity of the sediment basin at all times.
Use of Treatment Chemicals.  If you are using polymers, flocculants, or other treatment chemicals at your site, you must comply with the following minimum requirements:
Use conventional erosion and sediment controls prior to and after the application of treatment chemicals.  Use conventional erosion and sediment controls prior to chemical addition to ensure effective treatment.  Chemicals may only be applied where treated stormwater is directed to a sediment control (e.g., sediment basin, perimeter control) prior to discharge. 
Select appropriate treatment chemicals.  Chemicals must be selected that are appropriately suited to the types of soils likely to be exposed during construction and discharged to locations where chemicals will be applied, and to the expected turbidity, pH, and flow rate of stormwater flowing into the chemical treatment system or area.  
Minimize discharge risk from stored chemicals.  Store all treatment chemicals in leak-proof containers that are kept under storm-resistant cover and  surrounded by secondary containment structures (e.g., spill berms, decks, spill containment pallets), or provide equivalent measures, designed and maintained to minimize the potential discharge of treatment chemicals in stormwater or by any other means (e.g., storing chemicals in covered area or having a spill kit available on site). 
Comply with state/local requirements.  Comply with relevant state and local requirements affecting the use of treatment chemicals. 
Use chemicals in accordance with good engineering practices and specifications of the chemical provider/supplier.  You must also use treatment chemicals and chemical treatment systems in accordance with good engineering practices, and with dosing specifications and sediment removal design specifications provided by the provider/supplier of the applicable chemicals, or document specific departures from these practices or specifications and how they reflect good engineering practice. 
Ensure proper training.  Ensure that all persons who handle and use treatment chemicals at the construction site are provided with appropriate, product-specific training.  Among other things, the training must cover proper dosing requirements. 
Comply with additional requirements for the approved use of cationic chemicals.  If you have been authorized to use cationic chemicals at your site pursuant to Part 1.2.4, and the authorization is conditioned on your compliance with additional requirements necessary to ensure that the use of such chemicals will not cause an exceedance of water quality standards, you are required to comply with all such requirements. 
Provide proper SWPPP documentation.  You must include documentation in your SWPPP consistent with Parts 7.2.6.9 and 7.2.10.2 on the specific chemicals and chemical treatment systems you will use, and how you will comply with the requirements in this Part.   
Dewatering Practices.  You are prohibited from discharging ground water or accumulated stormwater that is removed from excavations, trenches, foundations, vaults, or other similar points of accumulation, unless such waters are first effectively managed by appropriate controls.  Uncontaminated, non-turbid dewatering water can be discharged without being routed to a control.  
               You must also meet the following requirements for dewatering activities:
Discharge requirements.
Do not discharge visible floating solids or foam;
Use an oil-water separator or suitable filtration device (such as a cartridge filter) that is designed to remove oil, grease, or other products if dewatering water is found to contain these materials;
To the extent feasible, utilize vegetated, upland areas of the site to infiltrate dewatering water before discharge.  In no case will surface waters be considered part of the treatment area;
At all points where dewatering water is discharged, comply with the velocity dissipation requirements of Part 2.1.3.1;
With backwash water, either haul it away for disposal or return it to the beginning of the treatment process; and
Replace and clean the filter media used in dewatering devices when the pressure differential equals or exceeds the manufacturer's specifications.
Treatment chemical restrictions.  If you are using polymers, flocculants, or other treatment chemicals to treat dewatering water, you must comply with the requirements in Parts 2.1.3.3. 
STABILIZATION REQUIREMENTS.
      You are required to stabilize exposed portions of your site in accordance with the requirements of this Part.  
         Note:  	For the purposes of this permit, "exposed portions of your site" means areas of exposed soil that are required to be stabilized.  Note that EPA does not expect that temporary or permanent stabilization measures to be applied to areas that are intended to be left unvegetated or unstabilized following construction (e.g., dirt access roads, utility pole pads, areas being used for storage of vehicles, equipment, or materials).
Deadlines for Initiating and Completing Stabilization.
Deadline to Initiate Stabilization.  You must initiate soil stabilization measures immediately whenever earth-disturbing activities have permanently or temporarily ceased on any portion of the site. 
                 Note:  	Earth-disturbing activities have permanently ceased when clearing and excavation within any area of your construction site that will not include permanent structures has been completed.
                 Note:  	Earth-disturbing activities have temporarily ceased when clearing, grading, and excavation within any area of the site that will not include permanent structures will not resume (i.e., the land will be idle) for a period of 14 or more calendar days, but such activities will resume in the future.  
                       The 14 calendar day timeframe above begins counting as soon as you know that construction work on a portion of your site will be temporarily ceased.  In circumstances where you experience unplanned or unanticipated delays in construction due to circumstances beyond your control (e.g., sudden work stoppage due to unanticipated problems associated with construction labor, funding, or other issues related to the ability to work on the site; weather conditions rendering the site unsuitable for the continuation of construction work) and you do not know at first how long the work stoppage will continue, your requirement to immediately initiate stabilization is triggered as soon as you know with reasonable certainty that work will be stopped for 14 or more additional calendar days.  At that point, you must comply with Parts 2.2.1.1 and 2.2.1.2.
                 Note:  	For the purposes of this permit, EPA will consider any of the following types of activities to constitute the initiation of stabilization:
   1.                           prepping the soil for vegetative or non-vegetative stabilization;
   2.                           applying mulch or other non-vegetative product to the exposed area; 
   3.                           seeding or planting the exposed area; 
   4.                           starting any of the activities in # 1  -  3 on a portion of the area to be stabilized, but not on the entire area; and
   5.                           finalizing arrangements to have stabilization product fully installed in compliance with the applicable deadline for completing stabilization in Parts 2.2.1.2 and 2.2.1.3. 
                        This list of examples is not exhaustive. 
                 Note:  	The term "immediately" is used to define the deadline for initiating stabilization measures.  In the context of this provision, "immediately" means as soon as practicable, but no later than the end of the next work day, following the day when the earth-disturbing activities  have temporarily or permanently ceased.
Deadline to Complete Stabilization Activities.  As soon as practicable, but no later than 14 calendar days after the initiation of soil stabilization measures consistent with Part 2.2.1.1, you are required to have completed:
For vegetative stabilization, all activities necessary to initially seed or plant the area to be stabilized; and/or
For non-vegetative stabilization, the installation or application of all such non-vegetative measures.
Exceptions to the Deadlines for Initiating and Completing Stabilization.  
Deadlines for projects occurring in arid or semi-arid areas, or drought-stricken areas.  These requirements apply if (1) your site is located in an arid area, a semi-arid area, or a drought-stricken area, as these terms are defined in Appendix A, (2) construction will occur during the seasonally dry period or during a period in which drought is predicted to occur, and (3) you are using vegetative cover for temporary or permanent stabilization.  You may also comply with the deadlines in Part 2.2.1.1 instead.  The deadlines for these types of projects are as follows:
Immediately initiate, and within 14 calendar days of a temporary or permanent cessation of work in any portion of your site complete, the installation of temporary non-vegetative stabilization measures to the extent necessary to prevent erosion; 
As soon as practicable, given conditions or circumstances on your site, complete all activities necessary to initially seed or plant the area to be stabilized; and 
If construction is occurring during the seasonally dry period, indicate in your SWPPP the beginning and ending dates of the seasonally dry period and your site conditions. You must also include the schedule you will follow for initiating and completing vegetative stabilization.
Deadlines for projects that are affected by circumstances beyond the control of the permittee that delay the initiation and/or completion of vegetative stabilization as required in Parts 2.2.1.1 and/or 2.2.1.2.  If you are unable to meet the deadlines in Parts 2.2.1.1and/or 2.2.1.2 due to circumstances beyond your control, and you are using vegetative cover for temporary or permanent stabilization, you may comply with the following stabilization deadlines instead: 
Immediately initiate, and within 14 calendar days complete, the installation of temporary non-vegetative stabilization measures to prevent erosion; 
Complete all soil conditioning, seeding, watering or irrigation installation, mulching, and other required activities related to the planting and initial establishment of vegetation as soon as conditions or circumstances allow it on your site; and
                           Note:  	You are required to have stabilized the exposed portions of your site consistent with Part 2.2.2 prior to terminating permit coverage under Part 8.2.
Document the circumstances that prevent you from meeting the deadlines required in Parts 2.2.1.1and/or 2.2.1.2 and the schedule you will follow for initiating and completing stabilization.
Deadlines for sites discharging to sensitive waters.  For any portion of the site that discharges to a sediment or nutrient-impaired water (see Part 3.2) or to a water that is identified by your state, tribe, or EPA as Tier 2, Tier 2.5, or Tier 3 for antidegradation purposes (see Part 3.3), you are required to complete the stabilization activities specified in Parts 2.2.1.2a and/or 2.2.1.2b within 7 calendar days after the temporary or permanent cessation of earth-disturbing activities.
                      Note:  	If you qualify for the deadlines for initiating and completing stabilization in Part 2.2.1.3a or b, you may comply with the stabilization deadlines in Part 2.2.1.3a or b for any portion of your site that discharges to a sensitive water.  
Criteria for Stabilization.
To be considered adequately stabilized, you must meet the criteria below depending on the type of cover you are using, either vegetative or non-vegetative.
Vegetative Stabilization.  
For all sites, except those located in arid or semi-arid areas or on agricultural lands.  
If you are vegetatively stabilizing any exposed portion of your site through the use of seed or planted vegetation, you must provide established uniform vegetation (e.g., evenly distributed without large bare areas), which provides 70 percent or more of the density of coverage that was provided by vegetation prior to commencing earth-disturbing activities.  You should avoid the use of invasive species;
For final stabilization, vegetative cover must be perennial; and 
Immediately after seeding or planting the area to be vegetatively stabilized, to the extent necessary to prevent erosion on the seeded or planted area, you must select, design, and install non-vegetative erosion controls that provide cover (e.g., mulch, rolled erosion control products) to the area while vegetation is becoming established.
For sites located in arid or semi-arid areas, or drought-stricken areas.  If you are located in an arid or semi-arid area, or a drought-stricken area, as these terms are defined in Appendix A, you are considered to have completed final stabilization if both of the following criteria are met:
The area you have seeded or planted must within 3 years provide established vegetation that covers 70 percent or more of the density of vegetation prior to commencing earth-disturbing activities; and
In addition to seeding or planting the area to be vegetatively stabilized, to the extent necessary to prevent erosion on the seeded or planted area, you must select, design, and install non-vegetative erosion controls that provide cover for at least 3 years without active maintenance by you.
For sites located on land used for agriculture.  Disturbed areas on land used for agricultural purposes (e.g., pipelines across crop or range land, staging areas for highway construction) that are restored to their pre-construction agricultural use are not subject to these final stabilization criteria.  Areas disturbed that were not previously used for agricultural activities, and areas that are not being returned to preconstruction agricultural use, must meet the conditions for stabilization in this Part.
Non-Vegetative Stabilization.  If you are using non-vegetative controls to stabilize exposed portions of your site, or if you are using such controls to temporarily protect areas that are being vegetatively stabilized, you must provide effective non-vegetative cover to stabilize any such exposed portions of your site.  
POLLUTION PREVENTION REQUIREMENTS.
      You are required to design, install, and maintain effective pollution prevention measures in order to prevent the discharge of pollutants.  Consistent with this requirement, you must:
            Eliminate certain pollutant discharges from your site (see Part 2.3.1); 
            Properly maintain all pollution prevention controls (see Part 2.3.2); and
            Comply with pollution prevention standards for pollutant-generating activities that occur at your site (see Part 2.3.3).
      These requirements apply to all areas of your construction site and any and all support activities covered by this permit consistent with Part 1.3.c.
Prohibited Discharges.
      You are prohibited from discharging the following from your construction site:
Wastewater from washout of concrete, unless managed by an appropriate control as described in Part 2.3.3.4;
Wastewater from washout and cleanout of stucco, paint, form release oils, curing compounds and other construction materials, unless managed by an appropriate control as described in Part 2.3.3.4;
Fuels, oils, or other pollutants used in vehicle and equipment operation and maintenance;
Soaps, solvents, or detergents used in vehicle and equipment washing; and
Toxic or hazardous substances from a spill or other release. 
General Maintenance Requirements.  
      You must ensure that all pollution prevention controls installed in accordance with this Part remain in effective operating condition and are protected from activities that would reduce their effectiveness.  You must inspect all pollutant-generating activities and pollution prevention controls in accordance with your inspection frequency requirements in Parts 4.1.2 or 3.2.2.1 to avoid situations that may result in leaks, spills, and other releases of pollutants in stormwater discharges to receiving waters, and must document your findings in accordance with Part 4.1.7.  If you find that controls need to be replaced, repaired, or maintained, you must make the necessary repairs or modifications in accordance with the following:
Initiate work to fix the problem immediately after discovering the problem, and complete such work by the close of the next work day, if the problem does not require significant repair or replacement, or if the problem can be corrected through routine maintenance.
When installation of a new pollution prevention control or a significant repair is needed, you must install the new or modified control and make it operational, or complete the repair, by no later than 7 calendar days from the time of discovery.  If it is infeasible to complete the installation or repair within 7 calendar days, you must document in your records why it is infeasible to complete the installation or repair within the 7 calendar day timeframe and document your schedule for installing the stormwater control(s) and making it operational as soon as practicable after the 7 calendar day timeframe.  Where these actions result in changes to any of the pollution prevention controls or procedures documented in your SWPPP, you must modify your SWPPP accordingly within 7 calendar days of completing this work. 
Pollution Prevention Standards.
      You are required to comply with the pollution prevention standards in this Part if you conduct any of the following activities at your site or at any construction support activity areas covered by this permit (see Part 1.3.c):
            Fueling and maintenance of equipment or vehicles;
            Washing of equipment and vehicles;
            Storage, handling, and disposal of construction materials, products, and wastes; and

Never apply to frozen ground;
Never apply to stormwater conveyance channels with flowing water; and
Follow all other federal, state, tribal, and local requirements regarding fertilizer application.

1. WATER QUALITY-BASED EFFLUENT LIMITATIONS.
 GENERAL EFFLUENT LIMITATION TO MEET APPLICABLE WATER QUALITY STANDARDS
      Your discharge must be controlled as necessary to meet applicable water quality standards.  You must also comply with any additional requirements that your state or tribe requires you to meet in Part 9.
      In the absence of information demonstrating otherwise, EPA expects that compliance with the conditions in this permit will result in stormwater discharges being controlled as necessary to meet applicable water quality standards.  If at any time you become aware, or EPA determines, that your discharge is not being controlled as necessary to meet applicable water quality standards, you must take corrective action as required in Part 5.2.1, and document the corrective actions as required in Part 5.2.2 and Part 5.4.
      EPA will also impose additional water quality-based limitations on a site-specific basis, or require you to obtain coverage under an individual permit, if information in your NOI, or from other sources indicates that your discharges are not controlled as necessary to meet applicable water quality standards. This includes situations where additional controls are necessary to comply with a wasteload allocation in an EPA established or approved TMDL.
 DISCHARGE LIMITATIONS FOR IMPAIRED WATERS
      If you discharge to a surface water that is impaired for (1) sediment or a sediment-related parameter, such as total suspended solids (TSS) or turbidity, and/or (2) nutrients, including impairments for nitrogen and/or phosphorus, you are required to comply with the requirements in Part 3.2.2.
         Note:  	For the purposes of this Part, "impaired waters" are waters identified as impaired on the appropriate CWA Section 303(d) list, or waters with an EPA-approved or established TMDL. Your construction site will be considered to discharge to an impaired water if the first surface water to which you discharge is identified by a state, tribe, or EPA pursuant to Section 303(d) of the CWA as not meeting an applicable water quality standard, or is included in an EPA-approved or established total maximum daily load (TMDL).  For discharges that enter a storm sewer system prior to discharge, the first surface water to which you discharge is the waterbody that receives the stormwater discharge from the storm sewer system.
      If you discharge to an impaired water that is impaired for a parameter other than a sediment-related parameter or nutrients, EPA will inform you if any additional limits or controls are necessary for your discharge to be controlled as necessary to meet water quality standards, including for it to be consistent with the assumptions of any available wasteload allocation in any applicable TMDL, or if coverage under an individual permit is necessary in accordance with Part 1.4.5.
      If during your coverage under a previous permit, you were required to install and maintain stormwater controls specifically to meet the assumptions and requirements of an EPA-approved or established TMDL (for any parameter) or to otherwise control your discharge to meet water quality standards, you must continue to implement such controls as part of this permit.
 Identify If You Discharge To An Impaired Water.
If you discharge to an impaired water, you must provide the following information in your NOI:
            A list of all impaired waters to which you discharge;
            The pollutant(s) for which the surface water is impaired; and
            Whether a TMDL has been approved or established for the waters to which you discharge.
 Requirements for Discharges to Sediment or Nutrient-Impaired Waters.
If you discharge to a surface  water that is impaired for (1) sediment or a sediment-related parameter (e.g., total suspended solids (TSS) or turbidity) and/or (2) nutrients (e.g., nitrogen and/or phosphorus), including impaired waters for which a TMDL has been approved or established for the impairment, you are required to comply with the following stormwater control requirements, which supplement the requirements applicable to your site in other corresponding parts of the permit
Frequency of Site Inspection.  You must conduct inspections at the frequency specified in Part 4.1.3.
Deadline to Complete Stabilization.  You must comply with the deadlines for completing site stabilization as specified in Part 2.2.1.3c.
State and Tribal Requirements.  You must comply with any additional state or tribal impairment-related requirements included in Part 9.
       EPA will also impose additional water quality-based limitations on a site-specific basis, or require you to obtain coverage under an individual permit, if it is determined that the controls in the Part will not be sufficient to control discharges consistent with the assumptions and requirements of an applicable wasteload allocation of an approved or established TMDL or to prevent the site from contributing to the impairment.  
 DISCHARGES TO WATERS IDENTIFIED AS TIER 2, TIER 2.5, OR TIER 3.
 Identify if You Discharge to a Tier 2, Tier 2.5, or Tier 3 Water.
If you discharge to a water identified by a state, tribe, or EPA as Tier 2, Tier 2.5, or Tier 3 water, you must provide on your NOI a list of waters identified as Tier 2, Tier 2.5, or Tier 3 to which you discharge.  See Appendix F for a list of Tier 2 and 3 waters in Idaho, Massachusetts, New Hampshire, and New Mexico.
         Note:  	For the purposes of this permit, you are considered to discharge to a Tier 2, Tier 2.5, or Tier 3 water if the first surface water to which you discharge is identified by a state, tribe, or EPA as Tier 2, Tier 2.5, or Tier 3.  Tiers 2, 2.5 and 3 refer to waters either identified by the state as high quality waters or Outstanding National Resource Waters under 40 CFR §131.12(a)(2) and (3).  For discharges that enter a storm sewer system prior to discharge, the surface water to which you discharge is the first surface water that receives the stormwater discharge from the storm sewer system.
 Requirements for New Projects Discharging to Tier 2, Tier 2.5, or Tier 3 Waters.
For new projects, if you will discharge to a Tier 2, Tier 2.5, or Tier 3 water, you are required to comply with the requirements in Parts 4.1.3  (inspection frequencies) and 2.2.1.3c (stabilization deadlines), and, if applicable, Part 9 (relevant state or tribal requirements).  In addition, on a case-by-case basis, EPA may notify operators of such new projects or operators of existing projects with increased discharges that additional analyses, stormwater controls, or other permit conditions are necessary to comply with the applicable antidegradation requirements, or notify you that an individual permit application is necessary in accordance with Part 1.4.5.
INSPECTIONS.
SITE INSPECTIONS.
Person(s) Responsible for Inspecting Site.
The person(s) inspecting your site may be a person on your staff or a third party you hire to conduct such inspections.  You are responsible for ensuring that the person who conducts inspections is a "qualified person."
         Note:  	A "qualified person" is a person knowledgeable in the principles and practice of erosion and sediment controls and pollution prevention, who possesses the skills to assess conditions at the construction site that could impact stormwater quality, and the skills to assess the effectiveness of any stormwater controls selected and installed to meet the requirements of this permit.
Frequency of Inspections.
At a minimum, you must conduct a site inspection in accordance with one of the two schedules listed below, unless you are subject to Part 4.1.3 or Part 4.1.4:
At least once every 7 calendar days; or
Once every 14 calendar days and within 24 hours of the occurrence of a storm event of 0.25 inches or greater.  To determine if a storm event of 0.25 inches or greater has occurred on your site, you must either keep a properly maintained rain gauge on your site, or obtain the storm event information from a weather station that is representative of your location.  For any day of rainfall during normal business hours that measures 0.25 inches or greater, you must record the total rainfall measured for that day in accordance with Part 4.1.7.1d.  
                 Note:  	Inspections are only required during the project's normal working hours.
                 Note: 	You are required to specify in your SWPPP which schedule you will be following.
                 Note: 	"Within 24 hours of the occurrence of a storm event" means that you are required to conduct an inspection within 24 hours once a storm event has produced 0.25 inches, even if the storm event is still continuing. Thus, if you have elected to inspect bi-weekly in accordance with Part 4.1.2.2 and there is a storm event at your site that continues for multiple days, and each day of the storm produces 0.25 inches or more of rain, you are required to conduct an inspection within 24 hours of the first day of the storm and within 24 hours after the end of the storm.
Increase in Inspection Frequency for Sites Discharging to Sensitive Waters.
      For any portion of the site that discharges to a sediment or nutrient-impaired water (see Part 3.2) or to a water that is identified by your state, tribe, or EPA as Tier 2, Tier 2.5, or Tier 3 for antidegradation purposes (see Part 3.3), instead of the inspection frequency specified in Part 4.1.2, you must conduct inspections in accordance with the following inspection frequencies: 
Once every 7 calendar days; and
Within 24 hours of the occurrence of a storm event of 0.25 inches or greater.  To determine if a storm event of 0.25 inches or greater has occurred on your site, you must either keep a properly maintained rain gauge on your site, or obtain the storm event information from a weather station that is representative of your location.  For any day of rainfall during normal business hours that measures 0.25 inches or greater, you must record the total rainfall measured for that day in accordance with Part 4.1.7.1d.
                 Note:  	Inspections are only required during the project's normal working hours.
                 Note: 	"Within 24 hours of the occurrence of a storm event" means that you are required to conduct an inspection within 24 hours once a storm event has produced 0.25 inches, even if the storm event is still continuing. Thus, if there is a storm event at your site that continues for multiple days, and each day of the storm produces 0.25 inches or more of rain, you are required to conduct an inspection within 24 hours of the first day of the storm and within 24 hours after the end of the storm.
                 Note: 	If you qualify for any of the reduced inspection frequencies in Part 4.1.4, you may conduct inspections in accordance with Part 4.1.4 for any portion of your site that discharges to a sensitive water.
Reductions in Inspection Frequency.
Your inspection frequency may be reduced as follows:
For Stabilized Areas.  You may reduce the frequency of inspections to once per month in any area of your site where the stabilization steps in Parts 2.2.1.2a and 2.2.1.2b have been completed.  If construction activity resumes in this portion of the site at a later date, the inspection frequency immediately increases to that required in Parts 4.1.2 or 4.1.3, if applicable.  You must document the beginning and ending dates of this period in your records.
For Arid, Semi-Arid, or Drought-Stricken Areas.  You may reduce the frequency of inspections to once per month and within 24 hours of the occurrence of a storm event of 0.25 inches or greater if your site is located in an arid, semi-arid, or drought-stricken area, as these terms are defined in Appendix A, and construction is occurring during the seasonally dry period or during a period in which drought is predicted to occur.  You must document that you are using this reduced schedule and the beginning and ending dates of the seasonally dry period in your SWPPP. To determine if a storm event of 0.25 inches or greater has occurred on your site, you must either keep a properly maintained rain gauge on your site, or obtain the storm event information from a weather station that is representative of your location.  For any day of rainfall during normal business hours that measures 0.25 inches or greater, you must record the total rainfall measured for that day in accordance with Part 4.1.7.1d.
                 Note:  	Inspections are only required during the project's normal working hours.
                 Note:  	"Within 24 hours of the occurrence of a storm event" means that you are required to conduct an inspection within 24 hours once a storm event has produced 0.25 inches, even if the storm event is still continuing. Thus, if there is a storm event at your site that continues for multiple days, and each day of the storm produces 0.25 inches or more of rain, you are required to conduct an inspection within 24 hours of the first day of the storm and within 24 hours after the end of the storm.
For Frozen Conditions.  
If you are suspending earth-disturbing activities due to frozen conditions, you may temporarily suspend inspections on your site until thawing conditions (see Appendix A) begin to occur if:
Runoff is unlikely due to continuous frozen conditions that are likely to continue at your site for at least 3 months based on historic seasonal averages.  If unexpected weather conditions (such as above freezing temperatures or rain on snow events) make discharges likely, you must immediately resume your regular inspection frequency as described in Parts 4.1.2 or 4.1.3, if applicable;
Land disturbances have been suspended; and 
All disturbed areas of the site have been temporarily or permanently stabilized in accordance with Part 2.2.  
If you are still conducting earth-disturbing activities during frozen conditions, you may reduce your inspection frequency to once per month if:
Runoff is unlikely due to continuous frozen conditions that are likely to continue at your site for at least 3 months based on historic seasonal averages.  If unexpected weather conditions (such as above freezing temperatures or rain on snow events) make discharges likely, you must immediately resume your regular inspection frequency as described in Parts 4.1.2 or 4.1.3 if applicable; and
Except for areas in which you are actively conducting earth-disturbing activities, disturbed areas of the site have been temporarily or permanently stabilized in accordance with Part 2.2.  
               You must document the beginning and ending dates of this period in your SWPPP.  
Areas that Need to Be Inspected.  During your site inspection, you must at a minimum inspect the following areas of your site:
All areas that have been cleared, graded, or excavated and that have not yet completed stabilization consistent with Part 2.2;
All stormwater controls (including pollution prevention measures) installed at the site to comply with this permit;
Material, waste, borrow, or equipment storage and maintenance areas that are covered by this permit;
All areas where stormwater typically flows within the site, including drainageways designed to divert, convey, and/or treat stormwater;
All points of discharge from the site; and
All locations where stabilization measures have been implemented.
      You are not required to inspect areas that, at the time of the inspection, are considered unsafe to your inspection personnel.    
Requirements for Inspections.  During your site inspection, you must at a minimum:
Check whether all erosion and sediment controls and pollution prevention controls are installed, appear to be operational, and are working as intended to minimize pollutant discharges.  Determine if any controls need to be replaced, repaired, or maintained in accordance with Parts 2.1.1.4 and 2.3.2;
Check for the presence of conditions that could lead to spills, leaks, or other accumulations of pollutants on the site;
Identify any locations where new or modified stormwater controls are necessary to meet the requirements of Parts 2 and/or 3;
At points of discharge and, if applicable, the banks of any surface waters flowing within your property boundaries or immediately adjacent to your property, check for signs of visible erosion and sedimentation (i.e., sediment deposits) that have occurred and are attributable to your discharge; and
Identify any and all incidents of noncompliance observed. 
If a discharge is occurring during your inspection, you are required to:
Identify all points of the property from which there is a discharge;  
Observe and document the visual quality of the discharge, and take note of the characteristics of the stormwater discharge, including color, odor, floating, settled, or suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollutants; and
Document whether your stormwater controls are operating effectively, and describe any such controls that are clearly not operating as intended or are in need of maintenance. 
Based on the results of your inspection, initiate corrective action under Part 5.

                      (2) For emergency-related construction activities, the requirement to train personnel prior to commencement of earth-disturbing activities does not apply, however, such personnel must have the required training prior to NOI submission. 
      You are responsible for ensuring that all activities on the site comply with the requirements of this permit.  You are not required to provide or document formal training for subcontractors or other outside service providers, but you must ensure that such personnel understand any requirements of the permit that may be affected by the work they are subcontracted to perform.  
      At a minimum, personnel must be trained to understand the following if related to the scope of their job duties (e.g., only personnel responsible for conducting inspections need to understand how to conduct inspections):
            The location of all stormwater controls on the site required by this permit, and how they are to be maintained;
            The proper procedures to follow with respect to the permit's pollution prevention requirements; and
            When and how to conduct inspections, record applicable findings, and take corrective actions.

STORMWATER POLLUTION PREVENTION PLAN (SWPPP).
GENERAL REQUIREMENTS.
Requirement to Develop a SWPPP Prior to Submitting Your NOI.
All operators associated with a construction project to be covered under this permit must develop a SWPPP.
         Note:  	You have the option of developing a group SWPPP where you are one of several operators who will be engaged in construction activities at your site.  For instance, if both the owner and the general contractor of the construction site are permitted, the owner may be the party responsible for SWPPP development, and the general contractor can choose to use this same SWPPP, as long as the SWPPP addresses the general contractor's scope of construction work and obligations under this permit.  
You are required to develop your site's SWPPP prior to submitting your NOI.  At a minimum, your SWPPP must include the information required in Part 7.2 and as specified in other parts of the permit.   You must also update the SWPPP as required in Part 7.4. 
         Note:  	If your project is an "existing project" (see Part 1.4.2.b) or if you are a new operator of an existing project" (see Part 1.4.2.c), and it is infeasible for you to comply with a specific requirement in this Part or in Parts 2.1, and 2.3.3 through 2.3.5 (except for Parts 2.3.3.1, 2.3.3.2b, 2.3.3.3c.i, and 2.3.3.4) because (1) the provision was not part of the permit you were previously covered under (i.e., the 2003 or 2008 CGP), and (2) because you are prevented from compliance due to the nature or location of earth disturbances that commenced prior to February 16, 2012, or because you are unable to comply with the requirement due to the manner in which stormwater controls have already been installed or were already designed prior to February 16, 2012, you are required to include documentation of the reasons why it is infeasible for you to meet the specific requirement, and then you may be waived from complying with this requirement.  You must include a separate justification why it is infeasible for you to meet each of the applicable requirements. 
If you prepared a SWPPP for coverage under a previous version of this NPDES permit, you must review and update your SWPPP to ensure that this permit's requirements are addressed prior to submitting your NOI.  
SWPPP CONTENTS.
      Your SWPPP must include the following information, at a minimum.
Stormwater Team.
Each operator, or group of multiple operators, must assemble a "stormwater team," which is responsible for overseeing the development of the SWPPP, any later modifications to it, and for compliance with the requirements in this permit.

Such controls would generally be considered Class V UIC wells:
Infiltration trenches (if stormwater is directed to any bored, drilled, driven shaft or dug hole that is deeper than its widest surface dimension, or has a subsurface fluid distribution system);
Commercially manufactured pre-cast or pre-built proprietary subsurface detention vaults, chambers, or other devices designed to capture and infiltrate stormwater flow; and
Drywells, seepage pits, or improved sinkholes (if stormwater is directed to any bored, drilled, driven shaft or dug hole that is deeper than its widest surface dimension, or has a subsurface fluid distribution system).
                  Note:  	For state UIC program contacts, refer to the following EPA website:  http://water.epa.gov/type/groundwater/uic/whereyoulive.cfm.
SWPPP Certification.
You must sign and date your SWPPP in accordance with Appendix I, Part I.11.
Post-Authorization Additions to the SWPPP.
Once you are notified of your coverage under this permit, you must include the following documents as part of your SWPPP:
A copy of your NOI submitted to EPA along with any correspondence exchanged between you and EPA related to coverage under this permit;
A copy of the acknowledgment letter you receive from the NOI Processing Center or eNOI system assigning your permit tracking number;
A copy of this permit (an electronic copy easily available to the stormwater team is also acceptable).
ON-SITE AVAILABILITY OF YOUR SWPPP.
      You are required to keep a current copy of your SWPPP at the site or at an easily accessible location so that it can be made available at the time of an on-site inspection or upon request by EPA; a state, tribal, or local agency approving stormwater management plans; the operator of a storm sewer system receiving discharges from the site; or representatives of the U.S. Fish and Wildlife Service (USFWS) or the National Marine Fisheries Service (NMFS).
      EPA may provide access to portions of your SWPPP to a member of the public upon request.  Confidential Business Information (CBI) will be withheld from the public, but may not be withheld from EPA, USFWS, or NMFS.  
            Note:  	Information covered by a claim of confidentiality will be disclosed by EPA only to the extent of, and by means of, the procedures set forth in 40 CFR Part 2, Subpart B. In general, submitted information protected by a business confidentiality claim may be disclosed to other employees, officers, or authorized representatives of the United States concerned with implementing the CWA. The authorized representatives, including employees of other executive branch agencies, may review CBI during the course of reviewing draft regulations.
      If an onsite location is unavailable to keep the SWPPP when no personnel are present, notice of the plan's location must be posted near the main entrance of your construction site.
REQUIRED SWPPP MODIFICATIONS.
List of Conditions Requiring SWPPP Modification.  
       You must modify your SWPPP, including the site map(s), in response to any of the following conditions:
Whenever new operators become active in construction activities on your site, or you make changes to your construction plans, stormwater control measures, pollution prevention measures, or other activities at your site that are no longer accurately reflected in your SWPPP.  This includes changes made in response to corrective actions triggered under Part 5.  You do not need to modify your SWPPP if the estimated dates in Part 7.2.5 change during the course of construction;
To reflect areas on your site map where operational control has been transferred (and the date of transfer) since initiating permit coverage;
If inspections or investigations by site staff, or by local, state, tribal, or federal officials determine that SWPPP modifications are necessary for compliance with this permit;
Where EPA determines it is necessary to impose additional requirements on your discharge, the following must be included in your SWPPP:
A copy of any correspondence describing such requirements; and
A description of the stormwater control measures that will be used to meet such requirements.
To reflect any revisions to applicable federal, state, tribal, or local requirements that affect the stormwater control measures implemented at the site; and
If applicable, if a change in chemical treatment systems or chemically-enhanced stormwater control is made, including use of a different treatment chemical, different dosage rate, or different area of application.

NHR100000: State of New Hampshire.
                If you disturb 100,000 square feet or more of contiguous area, you must also apply for an Alteration of Terrain (AoT) permit from DES pursuant to RSA 485-A:17 and Env-Ws 1500. This requirement also applies to a lower disturbance threshold of 50,000 square feet or more when construction occurs within the protected shoreline under the Shoreland Water Quality Protection Act (see RSA 483-B and Env-Ws 1400). A permit application must also be filed if your project disturbs an area of greater than 2,500 square feet, is within 50 feet of any surface water, and has a flow path of 50 feet or longer disturbing a grade of 25 percent or greater. Project sites with disturbances smaller than those discussed above, that have the potential to adversely affect state surface waters, are subject to the conditions of an AoT General Permit by Rule.
                You must determine that any excavation dewatering discharges are not contaminated before they will be authorized as an allowable non-stormwater discharge under this permit (see Part 1.3.d). The water is considered uncontaminated if there is no groundwater contamination within 1,000 feet of the source of the groundwater to be treated and discharged. Information on groundwater contamination can be generated over the Internet via the NHDES web site http://des.nh.gov/ at the OneStop Web Geographic Information System at http://www2.des.state.nh.us/gis/onestop. If it is determined that the groundwater to be dewatered is near a remediation or other waste site you must apply for the Remediation General Permit (see http://www.epa.gov/region1/npdes/rgp.html.)  
                You must treat any uncontaminated excavation dewatering discharges as necessary to remove suspended solids and turbidity. The discharges must be sampled at a location prior to mixing with stormwater at least once per week during weeks when discharges occur. Samples must be analyzed for total suspended solids (TSS) and must meet monthly average and daily maximum TSS limits of 50 milligrams per liter (mg/L) and 100 mg/L, respectively. TSS (a.k.a. Residue, Nonfilterable) sampling and analysis must be performed in accordance with Tables IB and II in 40 CFR 136.3 (see: http://www.access.gpo.gov/nara/cfr/waisidx_02/40cfr136_02.html). Records of any sampling and analysis must be maintained and kept with the SWPPP for at least three years after final site stabilization.
                Construction site owners and operators must consider opportunities for post-construction groundwater recharge using infiltration best management practices (BMPs) during site design and preparation of the stormwater pollution prevention plan (SWPPP). If your  construction site is in a town that is required to obtain coverage under the NPDES General Permit for discharges from Municipal Separate Storm Sewer Systems (MS4) you may be required to use such practices. The SWPPP must include a description of any on-site infiltration that will be installed as a post-construction stormwater management measure or reasons for not employing such measures such as 1) The facility is located in a wellhead protection area as defined in RSA 485-C:2; or 2) The facility is located in an area where groundwater has been reclassified to GAA, GAI or GA2 pursuant to RSA 485-C and Env-Ws 420; or 3) Any areas that would be exempt from the groundwater recharge requirements contained in Env-Ws 1507.04(e), including all land uses or activities considered to be a "High-load Area" (see Env-Wq 1502.26). For design considerations for infiltration measures see Volume II of the NH Stormwater Manual.
                Appendix F contains a list of Tier 2, or high quality waters. Although there is no official list of tier 2 waters, it can be assumed that all NH surface waters are tier 2 for turbidity unless 1) the surface water that you are proposing to discharge into is listed as impaired for turbidity in the states listing of impaired waters (see Surface Water Quality Watershed Report Cards at http://des.nh.gov/organization/divisions/water/wmb/swqa/report_cards.htm  or 2) sampling upstream of the proposed discharge location shows turbidity values greater than 10 NTU. A single grab sample collected during dry weather (no precipitation within 48 hours) is acceptable.
                To ensure compliance with RSA 485-C, RSA 485-A, RSA 485-A:13, I(a), Env-Wq 1700 and Env-Wq 302, the following information may be requested by NHDES. This information must be kept on site unless you receive a written request from NHDES that it be sent to the address shown in Part 9.1.2.7. 
                    A site map required in Part 7.2.6, showing the type and location of all post-construction infiltration BMPs utilized at the facility or the reason(s) why none were installed;
                    A list of all non-stormwater discharges that occur at the facility, including their source locations and the control measures being used (see Part 1.3.d). 
                    Records of sampling and analysis of TSS required for construction dewatering discharges (see Part 9.1.2.3).
                All required or requested documents must be sent to:

                Concord, NH 03302-0095
                When NHDES determines that additional water quality certification requirements are necessary to protect water quality, it may require individual discharges to meet additional conditions to obtain or continue coverage under the CGP. Any such conditions must be supplied to the permittee in writing. Any required pollutant loading analyses and any designs for structural best management practices necessary to protect water quality must be prepared by a civil or sanitary engineer registered in New Hampshire.

NMR100000: State of New Mexico, except Indian country.
                In addition to all other provisions of this permit, operators who intend to obtain authorization under this permit for all new and existing stormwater discharges must satisfy the following condition:
                The SWPPP must include site-specific interim and permanent stabilization, managerial, and structural solids, erosion, and sediment control best management practices (BMPs) and/or other controls that are designed to prevent to the maximum extent practicable an increase in the sediment yield and flow velocity from pre-construction, pre-development conditions to assure that applicable standards in 20.6.4 NMAC, including the antidegradation policy, or waste load allocations (WLAs) are met.  This requirement applies to discharges both during construction and after construction operations have been completed.  The SWPPP must identify, and document the rationale for selecting these BMPs and/or other controls.  The SWPPP must also describe design specifications, construction specifications, maintenance schedules (including a long term maintenance plan), criteria for inspections, and expected performance and longevity of these BMPs.  BMP selection must be made based on the use of appropriate soil loss prediction models (e.g., SEDCAD 4.0, RUSLE, SEDIMOT II, MULTISED, etc.), or equivalent, generally accepted (by professional erosion control specialists), soil loss prediction tools. The operator(s) must demonstrate, and include documentation in the SWPPP, that implementation of the site-specific practices will assure that the applicable standards or WLAs are met, and will result in sediment yields and flow velocities that, to the maximum extent practicable, will not be greater than the sediment yield levels and flow velocities from pre-construction, pre-development conditions.  The SWPPP must be prepared in accordance with good engineering practices by qualified (e.g., CPESC certified, engineers with appropriate training, etc.) erosion control specialists familiar with the use of soil loss prediction models and design of erosion and sediment control systems based on these models (or equivalent soil loss prediction tools). Qualifications of the preparer (e.g., professional certifications, description of appropriate training) must be documented in the SWPPP. The operator(s) must design, implement, and maintain BMPs in the manner specified in the SWPPP.
                Operators are not eligible to obtain authorization under this permit for all new and existing stormwater discharges to outstanding national resource waters (ONRWs) (also referred to as "Tier 3" waters). 
                The criteria for final stabilization in Part 2.2.2.1a is a "uniform vegetation (e.g., evenly distributed without large bare areas), which provides 70 percent or more of the density of coverage that was provided by vegetation prior to commencing earth-disturbing activities." The adjustment to allow for less than 100 % native vegetative cover (e.g., 50 % native vegetative cover x 70 % = 35 %) is acceptable. 
                Permittees can only use the criteria for final stabilization in Part 2.2.2.1b ("The area you have seeded or planted must within 3 years provide established vegetation that covers 70 percent or more of the density of vegetation prior to commencing earth-disturbing activities; and in addition to seeding or planting the area to be vegetatively stabilized, to the extent necessary to prevent erosion on the seeded or planted area, you must select, design, and install non-vegetative erosion controls that provide cover for at least 3 years without active maintenance by you") as a method for final vegetative stabilization for purposes of filing a Notice of Termination (NOT) under the following conditions:  
                 If this option is selected, you must notify NMED at the address listed in Part 9.4.1.5 at the time the NOT is submitted to EPA. The information to be submitted includes:
                * A copy of the NOT;
                * Contact information, including individual name or title, address, and phone number for the party responsible for implementing the final stabilization measures; and
                * The date that the permanent vegetative stabilization practice was implemented and the projected timeframe that the 70 % native vegetative cover requirements are expected to be met. (Note that if more than three years is required to establish 70 percent of the natural vegetative cover, this technique cannot be used or cited for fulfillment of the final stabilization requirement  -  you remain responsible for establishment of final stabilization). 
                 NMED also requires that operators periodically (minimum once/year) inspect and properly maintain the area until the criteria for final stabilization, as specified in Part 2.2 of the CGP, have been met. Operators must prepare an inspection report documenting the findings of these inspections and signed in accordance with Appendix I, Part I.11. This inspection record must be retained along with the SWPPP for three years after the NOT is submitted for the site and additionally submitted to NMED at the address listed in Part 9.4.1.5. The inspections at a minimum must include the following:
   *                 Observations of all areas of the site disturbed by construction activity; 
   *                 Best Management Practices (BMPs)/post-construction stormwater controls must be observed to ensure they are effective; 
   *                 An assessment of the status of vegetative re-establishment; and 
   *                 Corrective actions required to ensure vegetative success within three years, and control of pollutants in stormwater runoff from the site, including implementation dates.
                Copies of all documents submitted to EPA in non-electronic format must be sent to the following address:

                    The Pueblo of Sandia will not allow the Rainfall Erosivity Waivers (see Appendix C) to be granted for any small construction activities. 
                    The Stormwater Pollution Prevention Plan (SWPPP) must be available to the Pueblo of Sandia Environment either electronically or hard copy upon request for review. The SWPPP must be made available at least fourteen (14) days before construction begins. The fourteen (14) day period will give Tribal staff time to become familiar with the project site, prepare for construction inspections, and determine compliance with the Pueblo of Sandia Water Quality Standards. Failure to provide a SWPPP to the Pueblo of Sandia may result in denial of the discharge or construction delay. 
                    An "Authorization to Proceed Letter" with site specific mitigation, site and project requirements will be sent out to the permittee when a review of the NOI and SWPPP is completed by the Pueblo of Sandia Environment Department. This approval will allow the construction to proceed if all applicable requirements are met.   
                    Before submitting a Notice of Termination (NOT), permittees must clearly demonstrate to the Pueblo of Sandia Environment Department though a site visit or documentation that requirements for site stabilization have been met and any temporary erosion control structures have been removed. A short letter stating the stabilization requirements have been met will be sent to the permittee to add to the permittees NOT submission to EPA.  
                    Copies of all NOT submitted to the EPA must also be sent concurrently to the Pueblo of Sandia at the following address:
