TO:	Docket EPA-HQ-OW-2013-0652, for Alaskan Seafood Processing Effluent Limitations Guidelines, Notice of Availability of Data and Information

FROM:	U.S. Environmental Protection Agency

DATE:	August 2013

SUBJECT:	Report of Quality Activities Supporting Alaska Seafood Processing Cost Estimates

Background and Purpose of this Report
Background. The U.S. Environmental Protection Agency (EPA) received a petition from Alaskan seafood processors in 1980. This petition requested that EPA suspend regulations applicable to seafood processors in "non-remote" locations in Alaska. It also requested that EPA change the regulations using a rulemaking process. In a Federal Register notice dated January 20, 1981, EPA published a proposed response which would deny the petition and maintain the status of four of five locations (Anchorage, Cordova, Ketchikan, Petersburg) as "non-remote" processing locations, and would grant the petition for Juneau, thus proposing to change the status of that location to "remote." EPA also requested comment on additional locations that may have similar characteristics to the non-remote locations.  Finally, in the proposed response, EPA also indicated that the earlier suspension of the regulations for good cause would remain in effect until it issued a final response to the petition. However, EPA has not issued a final response to this 1980 petition or amended effluent limitations.
EPA estimated costs for direct discharging Alaska seafood processors associated with the petitioning locations of Cordova, Juneau, Ketchikan, and Petersburg to manage and dispose of seafood processing solids by 1) screening and transport for ocean disposal, and 2) screening, cooperative byproducts recovery, and ocean disposal of non-recoverable waste. EPA estimated costs for 15 surveyed processors in the petitioning locations and in the Kenai Peninsula, one of the additional locations being considered for reclassifying as non-remote, and three model plants. Surveyed processors are those that were surveyed in EPA's §308 questionnaire for the seafood processing industry and include nearly all of the processors in the petitioning locations. EPA used estimated costs for the three model processors to evaluate economic impacts for non-surveyed processors in the petitioning locations and the Kenai Peninsula. 
To estimate the costs, EPA developed waste management scenarios and assumptions documented in Outline of Costing Assumptions Alaska Seafood Processing in Non-Remote Processing Locations included in Appendix A of this memorandum. EPA then collected prices for purchasing and operating the equipment required to implement the scenarios. EPA used the prices, scenarios, and assumptions to develop an Excel spreadsheet for estimating costs. Then, using site-specific information from EPA's CWA §308 questionnaire, EPA estimated costs for 15 seafood processors located in five seafood processing locations to implement the waste management scenarios. 
Purpose of this Report. This report describes the activities EPA used to control the quality of these cost estimates. Plans for these quality control activities are detailed in Revised Draft Quality Assurance Project Plan: Support for EPA Response to Industry Petition on ELGs for Non-Remote Alaskan Seafood Processors, conditionally approved on November 29, 2010 (hereafter, the QAPP), and revised August 2013. 
Activities used to control cost estimate quality included:
Maintaining a project file of the collected cost data (i.e., pollution control technology equipment prices and unit prices).
Verifying that the collected cost data met the data acceptance specifications presented in QAPP Table 2-3;
For spreadsheets developed to estimate costs, checking spreadsheet data entry and calculations and documenting these checks; and
Verifying that the estimated costs met the quality specifications presented in QAPP Table 2-4.

Collecting Cost Data
EPA collected information about the costs for Alaskan seafood processors to install and operate wastewater pollution control technologies, including byproduct recovery processes and hauling waste for off-shore disposal. EPA obtained current (i.e., 2010 - 2011) cost information from equipment vendors, including both vendors that serve the Alaska areas included in this study and vendors that don't serve Alaska but sell the brands and models of equipment used in Alaska. In all cases, EPA added costs for shipping to each processing location to the quoted equipment costs.
In addition to equipment purchase and shipping, EPA obtained prices for fuel (electricity, gasoline, and diesel), labor, and shipping byproducts from the seafood processing location to Seattle. To estimate the costs of a building and a sump, EPA used standard R.S. Means construction costs and applied construction location factors to scale these costs to specific Alaska locations. 
EPA documented the source of all cost data. Vendor quotes, equipment brochures, and webpages were saved as pdf files and retained in the project file.
The criteria EPA used to evaluate the quality of collected pollution control technology cost information are summarized in Table 2-1 along with acceptable values for each criterion.

Evaluating Cost Data Quality
	While collecting cost data, EPA evaluated their quality to ensure they met the needs of the project. 

 Verifying Cost Data Quality: Comparing Collected Data to QAPP Data Acceptance Specifications
EPA used the Pollution Control Technology Cost Data Check List from QAPP Appendix B to document how the collected data met the cost data acceptance criteria. Checklist findings were recorded in a spreadsheet, a copy of which is included in Appendix B of this memo.  EPA's verification of how well the cost data met the quality specifications is presented, by acceptance criterion, in this section.
Currency. With the exception of vessel maintenance and insurance, all costs were collected from vendors or documented Internet sources in 2010 or 2011 and thus meet the currency specification.
To estimate the cost for vessel maintenance and insurance for scow, waste boat, and tender, EPA used the median annual maintenance costs for fishery vessels on the Great Lakes ($10,396/year), taken from Great Lakes Fisheries Vessels Status of the Fleet, 2001. For the bow picker, EPA estimated vessel maintenance and insurance at 7% of the cost of the boat. These estimates did not meet the specifications for currency or geographic scope. EPA considered these estimates to be "best available" and suitable for concept level cost estimates. 
Geographic Scope. EPA obtained costs for equipment appropriate for the "non-remote" areas of Alaska included in this study. Vendor quotes assumed delivery of equipment to Seattle, and EPA added costs for shipping the equipment from Seattle to each processing location. Also, for building costs, EPA used national average construction costs from R.S. Means, then adjusted the costs to the processing location locations using factors from Construction Cost Survey 2010, Alaska Housing Finance Corporation.
Accuracy/Reliability. As listed in Table 2-1, the specification for accuracy and reliability was that quotes be obtained from vendors who do business in the Alaska areas included in this study. Quotes for rotary wedge wire screens and "package" byproducts plants were obtained from vendors that do business in Alaska and thus met this specification. 
Although quotes for other equipment were from vendors that do not serve Alaska, they were obtained from vendors that sell the type and brands of equipment used in Alaska. For this reason, although the quotes did not meet the specification, in EPA's judgment, these quotes meet the criterion that the reported information is "true."
Comparability. EPA requested seafood processors report their annual costs for waste management (dollars per year) in the §308 questionnaire. EPA intended to use these reported costs to evaluate comparability. Many respondents did not respond to this question and those who did respond did not itemize the costs. For this reason, EPA did not systematically compare costs reported in the questionnaire responses to prices that EPA obtained for equipment, fuel, labor, and shipping. As a result, EPA could not systematically determine the comparability of the collected cost data. However, where individual questionnaire responses or other public sources included data applicable to costing scenarios applied to processors for which EPA developed costs, basic comparisons were made.
Regarding capital costs, during August 2010 visits to Alaska seafood processors (and in communication conducted as follow-up to the visits), EPA obtained equipment costs. Costs provided by seafood processors are compared to vendor prices in Table 3-1.

site visit report and APDES annual report
In 2009, waste was hauled daily during the salmon season to Bold Island by the Western Pioneer or Chichagof Shuttle vessel. These vessels have a capacity of 180,000 pounds each (in terms of pounds of waste). Waste was pumped from the vessels. The disposal vessel traveled about 12 miles out, to Bold Island. One trip required about an hour and a half to travel to the disposal site and about 1 hour to unload the boat and an hour and a half to return. The boat made one trip per day. Cost for waste disposal in 2009 was $139,553.
According to APDES annual report, in 2009, Alaska General operated 120 days and discharged 6.25 million pounds of waste.

As shown in Table 3-1, the vendor quotes for fish pumps EPA obtained from Fluid Process Equipment, Inc. are similar to the estimate provided by Rick Eaglin but lower than the estimate provided by Sandro Lane. Mr. Lane's higher cost represents a food grade (stainless steel pump), while the lower costs were for grade suitable for non-food grade material. EPA estimated costs for non-food grade pumps and concluded that the vendor quote was comparable to quotes from other sources. 
The off shore disposal operating costs EPA estimated included costs for operating the vessel, including labor, fuel, and vessel maintenance and insurance. The annual costs are a function of the size of the vessel crew, type of fuel used, and the number of trips required per year. Table 3-1 shows the range of annual costs EPA estimated for the 15 seafood processors. EPA's estimated costs are similar to the costs reported by an unnamed source. The costs reported by Alaska General Seafood are higher than EPA's estimated costs; however, Alaska General managed more waste than the processors for which EPA estimated costs. EPA concluded that its estimated waste disposal costs were comparable to the costs reported by the unnamed source and Alaska General. 
Reconciling Data Quality With User Requirements 
As discussed in Section 3.1, some collected data did not meet the data acceptance specifications (Table 2-1). EPA determined how these off-specification data would be used to estimate costs, as discussed in this section. 
Several quotes for equipment costs did not meet the specification to obtain estimates from a vendor that does business in the Alaska areas included in this study. EPA concluded that these are usable, because EPA added costs to ship equipment from Seattle to each analyzed processing location. This represents costs that processors would pay for equipment. Further, the estimated for vessel maintenance and insurance did not meet the currency specification of 2009  -  2011. EPA concluded that this estimated rate was usable because any potential inaccuracy was small compared to the total estimated costs. 
Using its engineering experience and judgment, and based on cost data quality review, EPA concluded that the price information collected for labor, fuel, packaging materials, laboratory analysis, and shipping was usable for this project.
Byproducts Recovery Plants. EPA contacted four companies that sell seafood byproducts equipment. After a telephone discussion explaining the project and the required costs, EPA requested a price quote for a complete "package plant" to produce salmon oil and salmon meal from seafood processing waste. Only the response from ANCO-EAGLIN provided a complete, detailed quote, suitable for use in the cost estimate. An assessment of the usability of each vendor's price quotes is presented in Table 3-2.

Alfa-Laval
Provided itemized quote for producing fish oil. Did not include fish meal production. No details for operating cost estimates.
ANCO-EAGLIN
Provided detailed itemized quote for producing fish oil and fish meal. Provided itemized equipment list, prices, estimated installation labor, and equipment layout for determining building sizes. Cost included boiler and air pollution control equipment and sufficient detail to estimate operating costs.
GEA Westphalia
Provided quote for three sizes of package fish oil plant and one combined fish oil/fish meal plant. No equipment list. Insufficient details for operating cost estimates.
Haarslev
Did not respond to request for quote.

After reviewing these assessments, EPA concluded that only the ANCO-EAGLIN quote was usable for developing cost estimates. The quotes from Alfa-Laval and GEA Westphalia were compared to the ANCO-EAGLIN quote but not used to develop costs. 
Estimating Pollution Control Technology Costs 
EPA applied direct and indirect escalation factors to the collected equipment purchase cost data to estimate equipment installed costs and then developed equations (curves) to relate equipment size and cost. EPA developed a detailed spreadsheet for estimating capital costs and operating and maintenance costs using the cost curves, assumptions about how each processor would implement the two waste management scenarios, and unit costs for labor, energy, packaging, and shipping. Production and wastewater data for each processor were pulled into the spreadsheet to calculate the costs for each processor. Finally, the estimated costs were used to analyze the economic impact of these estimated costs on the seafood processors and the firms that owned them. 
The development and review of the estimated costs is described in the following sections:
	4.1	Developing and Reviewing Costing Scenarios and Assumptions;
	4.2	Using Escalation Factors to Account for Direct and Indirect Capital Costs in Calculating Installed Capital Costs;
	4.3 	Developing Cost Curves;
	4.4	Extracting Facility Data from the Questionnaire Database; and
	4.5	Developing and Checking the Cost Calculation Spreadsheet.

Developing and Reviewing Costing Scenarios and Assumptions
To estimate costs, EPA developed detailed descriptions of the two scenarios for waste management and documented these descriptions and the planned costing approach in a draft outline of scenarios and assumptions. The Project QA Coordinator and another senior engineer knowledgeable in the development of effluent limitations guidelines, reviewed this outline and discussed it with the project manager. After addressing the review comments, a draft outline was provided to the EPA project team. The project engineers and economists discussed the draft outline. The engineering team revised the draft outline based on that discussion and added a new section (modeling and financial impacts for non-questionnaire plants) based on discussions between engineers and economists, and the revised outline was completed. These two drafts each included two versions of the byproducts recovery scenario. Scenario 2a was a worst-case scenario that assumed that each individual seafood processor would construct a separate byproducts recovery plant. This worst-case was based on the assumption that seafood processor with different owners would not cooperate with byproduct recovery. During the completion of the cost estimates, EPA decided to omit Scenario 2a from the preliminary cost estimates. 
As EPA developed preliminary and then final cost estimates, the assumptions were revised slightly to better reflect Alaska conditions and seafood processor baseline conditions.
Using Escalation Factors to Account for Direct and Indirect Capital Costs in Calculating Installed Capital Costs
EPA used the equipment and unit purchase cost data described in Section 2 of this memorandum to develop a set of equations for estimating the installed capital cost of implementing the two scenarios at each individual processor. To estimate installed capital costs, EPA applied direct and indirect escalation factors to the equipment and unit purchase costs as described in the memorandum, Direct and Indirect Escalation Cost Factors for Developing Budgetary Estimates for Waste Handling at Seafood Processing Facilities included in Appendix C. As described in that memorandum, EPA has used these cost factors in numerous past projects and found the resulting cost estimates agree very well with detailed cost estimates provided by construction companies. 
Developing Cost Curves
EPA applied appropriate escalation factors to the collected equipment and unit cost data to estimate installed capital costs, then developed equations (cost curves) relating installed capital costs to equipment size (in terms of wastewater flow). To develop these curves, EPA entered escalated cost and size information into an Excel spreadsheet, and then used the built-in charting and regression functions to plot the cost data as a function of size to calculate the line of best fit. The equipment cost equation (cost curve) was copied into the cost estimate spreadsheet. 
An engineer experienced with cost estimations provided technical review of the cost curves. The engineer reviewed the input of vendor information into the cost curve development spreadsheet, checked that escalation factors had been applied consistently, and verified that the cost equations were developed correctly and that they covered the ranges of sizes needed for the seafood processors. The engineer provided a written report of his review. Cost curves developed for this project are listed in Table 4-1.

For certain equipment (vessels and flow meter/totalizers), EPA did not develop cost curves but used a slightly different approach. For vessels, EPA included costs for one of four sizes of vessels, depending on the monthly average pounds/day of waste generated by the  processors during salmon season. Similarly, EPA included costs for one of five sizes of flow meters, depending on the maximum daily flow (gpm) at the individual processor. 
Extracting Facility Data from the Questionnaire Database 
Installed capital and annual operating and maintenance costs are based on the maximum amount of wastewater generated and the amount of waste generated at a seafood processor. EPA extracted production and waste generation data from the seafood processing questionnaire database and used these data to estimate wastewater flow and salmon and non-salmon season waste generation. These data were organized in an Excel spreadsheet and became input for estimating individual seafood processor costs. 
The questionnaire data required to calculate inputs for the cost spreadsheet were identified and extracted from the questionnaire database. An engineer not directly involved with the project provided independent technical review of the queries, to verify they retrieved the required information.
The cost spreadsheet inputs are summarized in Table 4-2 along with a discussion of how the questionnaire data were used in the calculation of the required inputs.

Q B-12
To calculate the average non-salmons season waste in lbs /day, the average lbs per day of production by month In B-12 is multiplied by the percent yield to waste in B-24 by species/seafood product. The lbs per day rate of all species/seafood product were then summed by month. The average non-salmon season waste is the highest rate of waste generation in any of the months excluding June through August.

gal/min
 
Calculated
To calculate the average wastewater flow in gal/min, the annual salmon production (i.e. fresh/frozen and canned salmon) is averaged over 2005 through 2009. This average is then multiplied by the production normalized flow of 3,400 gal/ton over the 91 days of salmon season.

Developing and Checking the Cost Calculation Spreadsheet
EPA developed a detailed spreadsheet for estimating total installed capital costs and operating and maintenance costs for each individual processor. The spreadsheet used the equations (cost curves) for installed capital costs; assumptions about how each seafood processor would implement the two waste management scenarios; unit costs for labor, energy, packaging, and shipping; and production and wastewater information for each seafood processor  to calculate the costs for each processor to manage and dispose of its waste solids. EPA developed preliminary cost estimates, they were reviewed, and revised costs were completed. 
EPA used the spreadsheet to calculate total installed capital and annual operating and maintenance costs for the 15 seafood processors included in EPA's survey. EPA also estimated costs for three model plants which the economists used to estimate impacts for facilities that EPA did not survey, including facilities in the processing locations being considered for addition to the list of non-remote processing locations.
For the 15 seafood processors surveyed, EPA zeroed out any costs the processor had already incurred (for example, if the processor currently owns and operates a waste disposal vessel, calculated costs for the vessel and its operation were set to zero). 
After delivering the preliminary costs, EPA developed a revised cost estimate spreadsheet that received additional review before revised costs were delivered to the economists. The calculation spreadsheet received several reviews:
A scientist checked that the calculations reflected the assumptions outlined in the Outline of Costing Assumptions Alaska Seafood Processing in Non-Remote Processing Locations. Where the calculations and assumptions documentation did not agree, the project manager determined if the documentation or calculations required corrections and ensured the corrections were made.
A scientist involved in the spreadsheet development checked the accuracy of the calculations in the preliminary spreadsheet. 
An engineer provided independent technical review of the preliminary and revised spreadsheets. He checked that the calculation description matched the cell formula and that cell references were correct. The engineer checked that units were converted properly and provided the spreadsheet developer with a written summary of the data checked, errors or problems found, and recommended revisions. (See 4.3 for a discussion of his review of the cost curves.)
A project manager reviewed the costs by comparing the estimates for each processor and evaluating whether the trends in costs reflected the amount of seafood processed and the baseline waste management strategies. 
After delivering the preliminary costs to the economists, the project team met to review the cost development. 
Quality activities related to the development of the cost estimate spreadsheet are listed in Table 4-3.

Cost Estimate Documentation
EPA identified the preliminary cost calculation spreadsheet as "draft." Revised versions are named AK Seafood Cost Calculations Month 2011.xlsx with Month replaced with the name of the month in which the file was delivered. When the spreadsheet is added to the docket supporting EPA's Notice of Data Availability (NODA), the file will be renamed AK Seafood Cost Calculations FINAL 2011.xlsx. EPA will assign a dcn, store the file in the electronic project file, and index it using the procedures outlined in the Project File Management Plan. 
Evaluating Cost Estimate Quality
Verification of the completed cost estimates means determining if estimated costs meet the data acceptance criteria specified in Table 2-4 of the QAPP. The results of this determination are presented in Section 5.1 and the use of the cost estimates is discussed in Section 5.2.
Verifying Cost Estimate Quality: Comparing Estimated Costs to QAPP Quality Specifications
Cost estimate quality specifications are presented Table 2-4 of the QAPP. The first acceptance criterion is that the costs meet the requirements for economic analysis. The specifications for this criterion were that the estimates include both one-time costs for equipment purchase, installation, and other direct and indirect capital costs and on-going operating and maintenance costs. The costs estimates fully met these specifications and were used by the economists to ultimately prepare: Costs and Economic Impact Analysis for Alaska Seafood Processors (Facilities and Firms) DCN 00428.
Table 5-1 reproduces the QAPP cost estimate quality specifications along with an assessment of whether the estimated costs met the specifications.

[a]Costs for boiler feed chemicals, used in Scenario 2, were not site-specific, but represent less than 0.5% of the annual costs for byproduct plant operation.
To evaluate the reasonableness of the cost estimate, EPA planned to compare its estimated costs to costs for similar installations at similar seafood processors. During August 2010 visits to Alaska seafood processors and follow-up to the visits, EPA sought costs for similar installations but obtained only limited information. Table 5-2 presents costs provided by Alaska General Seafood in Ketchikan for converting from discharging ground up solid waste through its Tongass Narrows outfall to hauling it to Bold Island. The Alaska General costs are compared to EPA's costs estimated for a similar sized installation.

Grinding waste to less than 0.5 inch in any dimension required several steps. Heads were ground in a hammer mill. The ground heads combined with other waste then passed through the Vaughan chopper pump, Muffin Monster, dewatering screen, and Autio grinder, and was then pumped into the boat. Dewatering was accomplished with a rotary screen, 0.100 inch mesh size. Dewatered waste was pumped to the vessel using a progressive cavity pump after it passed through the Autio grinder. When AGS converted from discharging ground up solid waste through its Tongass Narrows outfall to hauling it to Bold Island, they installed a concrete pad on land with waste disposal equipment at a capital cost of $165,000. No alterations or expansion to the existing dock were required.

Scenario 1 includes costs for:
Pump (waste from existing sump to screen)
Rotary wedge wire screen
Screen building
Waste hopper
Move existing grinder 
Vessel (scow)
New sump for screened wastewater
Wastewater discharge pump
Monitor screened wastewater for TSS and O&G

Limit to EPA Estimated Costs for:
Pump (waste from existing sump to screen)
Rotary wedge wire screen
Waste hopper
Move existing grinder pump 

$292,000



EPA's estimated costs for Scenario 1 are significantly greater than the costs Alaska General reported incurring to convert from discharge through an outfall to hauling waste for off shore disposal. EPA's costs for Scenario 1 are more than three times higher than costs reported by Alaska General, but include elements such as a vessel, screen building, new sump, and new sump pump that Alaska General did not need. Limiting the costs to elements that reflect the changes Alaska General made reduced EPA's estimated costs to $292,000 compared to $165,000. Although EPA's estimated costs are still greater than the Alaska General reported costs, they are reasonable given EPA's limited information about the size and layout of the seafood processing plant.
EPA will include estimated costs in the docket supporting the Federal Register NODA. The NODA and supporting data will be open for public comment. EPA expects additional validation of the waste management cost estimate through the public comment process. 	
Validating Cost Estimates and Reconciling Estimate Quality with User Requirements 
According to EPA's Guidance for QAPPs (QA/G-5), data validation is "an analyte- and sample-specific process that extends the evaluation of data beyond method, procedural, or contractual compliance (i.e. data verification) to determine the analytical quality of a specific data set." Although EPA did not validate the cost estimates, EPA may do so by using engineering judgment to evaluate whether the estimates "make sense" in the context of their knowledge of the Alaska seafood processing industry. This evaluation may include analysis of the results, for example calculation of the total annualized costs per ton of waste processed. EPA may investigate the input data and assumptions for processors with the highest (or lowest) estimated unit costs and use engineering judgment to understand whether the result is logical given the processor's circumstances. 
The cost estimates must be reviewed to determine if they can be used to answer the key questions identified in Section 2.2 of the QAPP, in particular:
What technologies for control of wastewater pollutant discharges from Alaskan seafood processors are technically and logistically feasible for facilities in non-remote locations?
What would implementation of these technologies cost?

This quality activity report will support EPA in making this determination.
Costing Documentation
Details of costing calculations are provided in individual documents included in Docket EPA-HQ-OW-2013-0652, supporting the Alaskan Seafood Processing Effluent Limitations Guidelines, Notice of Availability of Data and Information. These documents are listed in Appendix E. 

Pollutant Removals
EPA developed estimates of the incremental effluent reduction benefits (pounds of pollutants removed) for screening versus grinding. Typically, EPA estimates the discharges of pollutants at baseline (in this case, grinding) and compares them to discharges assuming the technology basis is installed (in this case screening). EPA could not use its standard approach for developing reductions in TSS and oil and grease because it does not have baseline information on TSS and oil and grease discharges. Facilities that employ grinding do not monitor for TSS and oil and grease. Rather, they collect data on the mass of incoming raw product and the mass of the final product. As a result, for today's notice and in the analysis supporting EPA's 1981 proposed petition response, EPA used total waste generated (i.e., difference between the mass of incoming product minus the mass of the final product) as a proxy for the pounds of pollutants removed that would no longer be discharged in the facility effluent with the addition of screening. This is appropriate because, as indicated above, total waste generated is regularly reported utilizing mass balance data regularly collected by processors for weights of incoming raw product and final products. Moreover, available mass balance data also show that facilities using screening technology and by-product recovery achieve waste removals in excess of 90 percent.
EPA estimated total loads of waste generated for individual processing facilities using data provided by processors in NPDES permit annual reports and reported in questionnaire responses. Processors report tons of waste generated by subtracting the tons of final product from the tons of raw product. Raw and final product weight data are extensive and reliable. Raw product weights are derived from carefully weighed incoming fish landings, which serve as the basis for paying fishermen for their catch. These fish landing weights are also reported to Alaska state agencies to determine state taxes. Final products are weighed carefully for packaging and related purposes.

--------------------------------------------------------------------------------


         1. Introduction
EPA estimated incremental facility specific costs for direct discharging Alaska Seafood Processing facilities associated with the petitioning locations of Cordova, Juneau, Ketchikan, and Petersburg to meet the ELGs as promulgated for non-remote locations.  EPA conducted its analysis for two scenarios: 
      Scenario 1:  Screening and discharge of resulting wastewater and transport of screened solids for ocean disposal, and 
      Scenario 2b: Screening and discharge of resulting wastewater and cooperative by-product recovery of screened wastes.
EPA also estimated incremental facility specific costs for facilities located in the Kenai Peninsula and Sitka processing locations, currently classified as remote. As indicated in EPA's proposal (46 FR 2546. (January 9, 1981), EPA is considering reclassifying these locations as non-remote.  No direct dischargers are currently located in Anchorage, another original petitioning location. Dutch Harbor, although surveyed, is not included in this analysis because all three facilities that have operated there over the long term have installed screening technology as well as individual by-product recovery and already comply with the non-remote ELGs as promulgated. Therefore, no additional costs would be incurred by these three facilities. 
This report documents assumptions EPA used to develop cost estimates. The project economists used the facility specific costs to develop  total annualized costs and industry wide total annualized compliance costs estimates and to evaluate the financial and economic impacts of these costs and presented the results in Report to the Record Costs and Economic Impact Analysis for Alaska Seafood Processors (Facilities and Firms), DCN 00428. 
The cost estimates reflect the amount and type (salmon vs. non-salmon) of waste generated at the affected plants and costs to purchase, install, and operate appropriately sized equipment. Consistent with costing estimates for the existing regulation, these conceptual-level cost estimates do not identify equipment installation locations or the location of individual project components (e.g., large pieces of equipment, buildings, etc.) Rather, EPA accounted for this through general costing factors and contingencies to cover possible site-specific layouts and features. Preliminary cost estimates, developed using the agreed on assumptions, were used to develop a preliminary financial and economic analysis. After initial reviews, EPA revised the preliminary costs. The revisions refined some assumptions related to the vessels used for off shore disposal and corrected errors. Major revisions included:
Adding a fourth size of vessel for hauling waste disposal, with a waste capacity of 60,000 tons, more than the smallest vessel (16,000 ton bow picker) and less than the next largest vessel (100,000 ton scow). 
Increasing the hours the waste disposal vessel crew was assumed to work during salmon season, from only the hours the vessel was loaded, unloaded, and underway to 728 hours per season (8hr/day x 91 days/season). For non-salmon season, EPA continued to assume the crew worked the hours the vessel was loaded, unloaded, and underway.
For the annual costs for operating the byproducts recovery plant in Petersburg, correcting an error calculating the cost for trucking the waste from the processing plant to the assumed byproducts plant location. These costs are estimated as $10/metric ton of waste. For the preliminary estimate, EPA mistakenly calculated these costs based on the annual salmon season waste volume multiplied by 91 day salmon season, resulting in a cost of $2.2 million per year. This cost was corrected to $24,688 per year.
For the capital cost for the rotary wedge wire screen, EPA included only equipment costs and mistakenly omitted the other direct costs (electrical, plumbing, and mechanical costs related to installation) and the indirect costs (related to contractor expenses - engineering, permits, scheduling, performance bonds, insurance, markup, overhead and profit).
Other changes with less impact on the total costs included:
Adding site-specific shipping costs as estimated by Lynden Shipping (Lynden's quote did not arrive until after the preliminary costs were completed);
Updating the diesel, gasoline, and electricity costs (due to the very rapid increase in fuel costs during the spring of 2011).

      * Monitor screened wastewater for TSS and O&G 
      * Measure volume of wastewater discharged
      * Discharge screened wastewater through existing outfall


General Costing Assumptions
For this cost estimate, EPA assumed that plants will only recover byproducts during 91 day salmon season. Information acquired primarily from industry sources indicates the non-recoverable portion of salmon waste is approximately five percent. Outside of salmon season, all waste will be hauled offshore for disposal. This assumption is applied to both Scenarios 1 and 2b for which costs were developed.
6.1 Scenario 1- Screen and Haul
   * Wastewater will be collected in the existing sumps prior to screening
         o Screen cost based on maximum flow rate 
               # peak production rate X 3,400 gal/ton raw fish processed
         o Costs from Parkson and IPEC rotary screens
   * Wastewater will be pumped to a rotary screen from the existing sump using new pumps
         o Include costs for 2 pumps 
         o Pump sized based on lb/day fish waste to screen
         o Type of pumps (Moyno positive displacement pumps)
         o Size of pumps 
               # Assumed 30 ft head
               # Estimated required pump horsepower;
               # EPA estimated electric power in kilowatts (kW) from pump horsepower multiplied by 0.7457 kW/horsepower, then multiplied the kWhr by the operating hours per year to determine total kWh/yr. 
         o Include plumbing and electrical hook up allowance as percent of equipment costs
   * Screen, 0.5 - 0.7 mm wedge wire, Parkson or IPEC
         o Operating costs based on motor HP and operating hours per year 
         o Solids will discharge to a hopper 
               # Hopper size based on lb/day salmon season waste
         o Assumed screen will require construction of a new heated building and a concrete pad, located adjacent to existing plant and dock  
         o Assumed plants have space to construct screen building
         o Assumed screened wastewater flows by gravity to new discharge sump 
   * Screened solids management
         o Screened solids will be pumped from the hopper to waste boat
               # Pumping will use existing grinder pump, allowance for relocating the pump to the hopper exit
               #  Solids are discharged from the screen at 20% solids
   * Off shore hauling will be in bow picker, work vessel, fishing scow, or tender
         o Waste boat size based on average pounds waste/day during heavy (salmon) season
         o Trips per year = total waste per year/boat load 
         o Check number of trips required for peak week 
               # If significantly more than 2 trips/day, use a larger boat
         o Capital costs to purchase vessel include off-loading pump
         o Operating costs for labor (captain and 1-3 hands), fuel, and maintenance
         o Assumed crew is paid for full 91 day salmon season and for waste disposal runs during non-salmon season
         o Assumed 10 mile RT for waste disposal
   * No additional dock space is required - waste boat loading will be scheduled with fishing vessel unloading.
         o the docks are not constantly occupied by fishing vessels (EPA observation)
         o processors that are currently required to haul waste have not built a new dock for the waste boat
Monitoring
         o Use the requirements from Kodiak general permit (e.g., wastewater flow and weekly grab samples for TSS, O&G, pH) 
         o Assumed plant will send samples to a lab for TSS and O&G and estimated costs per sample, including shipping costs; run pH onsite.
         o Assumed plants will no longer be required to conduct a dive survey (ignored cost savings: insignificant)
         o Assumed facilities will be required to install a flow meter
         o Assumed labor costs for increased record keeping and reporting (3 hr/week of operation for a QC technician)
   * Screened wastewater will flow into a new discharge sump
         o Assumed new sump will be located next to existing sump and not require demolition or removing existing concrete
         o Include costs for new discharge pumps 
         o Existing outfall pipe used to discharge screened wastewater. 
Scenario 2a - Individual processing plant onsite byproducts recovery of salmon waste  
Not costed.
Scenario 2b - Combined processing location byproducts recovery of salmon waste 
   * A best-case scenario, assuming that existing and planned byproducts recovery plants that currently take waste from other companies will continue to do so.
   * Plants will incur all of the capital costs for Scenario 1, screen and haul 
         o Plants that cooperate to process byproducts will cooperate in owning and operating a waste disposal vessel
         o Vessel will be smaller, because less waste to haul
   * For existing and planned byproducts recovery plants, EPA assumed
         o Icicle plants in Seward and Petersburg that operate their own byproducts recovery will continue to refuse other plants' waste 
         o Trident plants in Ketchikan and Cordova that operate byproducts recovery will accept and have capacity for all salmon season waste from the other plants in Ketchikan and Cordova 
         o Scientific Fisheries that operates a byproducts recovery plant in Kenai has capacity for Kenai waste (except Icicle) or will expand as needed to accommodate the waste
         o Assumed that the Sitka Meal Oil and Gelatin plant will be built in Sitka and will take all of the salmon-season waste from the three Sitka facilities 
         o The owner of the byproducts plant will receive all of the profit
         o Waste generators are not paid for their waste but do not need to pay to truck their waste to the byproducts plant
         o The existing byproducts plant will also operate a waste disposal boat that will dispose of all non-recoverable processing waste 
         o All waste generators will share the cost of non-recoverable waste disposal in proportion to the amount of waste they generate. If they already operate a vessel, they will have no additional vessel costs from Scenario 2b. 
         o In short, for processing locations with existing byproduct recovery, under Scenario 2b processors have the same costs as for Scenario 1, except they have less waste to haul off shore and they cooperate in the off shore disposal, resulting in lower waste disposal costs.
            
   * For new byproducts recovery facilities, EPA assumed
         o Trident and Ocean Beauty will cooperate to build a new byproducts plant in Petersburg 
               # Space and infrastructure are available at Trident's Mitkof plant (currently not operating)
               # No costs for land, cost for renovating the existing building
               # Both Trident and Ocean Beauty will have costs to truck waste to the new combined byproducts plant (assumed $10/metric ton).
         o Taku and Alaska Glacier will cooperate to build a new byproducts plant in Juneau 
               # Neither processor has space for the byproducts plant
               # Land and building required for new plant
               # Both Taku and Alaska Glacier will have costs to truck waste to the new combined byproducts plant (assumed $10/metric ton).
         o Costs and profits will be distributed to the participants in the new ventures in proportion to the amount of waste processed
               # Cost model estimates product yield
               # Salmon oil yield: 2% of total salmon season raw waste weight
               # Salmon meal yield: 20% of total salmon season raw waste weight
   * Assumed  plant as costed by ANCO-Eaglin is used to produce oil and meal
         o Other equipment costs included (diesel fuel tank, CIP system)
         o Include other one-time costs 
               # Permitting (e.g., CAA permit for diesel-fueled boiler, SPCC plan )
               # Engineering
               # Equipment shipping from Seattle to Petersburg or Juneau
               # Installation
               # Contractor costs
         o Operating costs (power, steam, packaging, transportation of product to Seattle)
               # Assumed the facilities use plastic-lined SpaceKraft totes for oil and SuperSacks for meal. 
               # Assumed the product can be loaded directly from the meal plant to the SuperSack tote.
               # Packaging costs do not include costs for nitrogen layering of the salmon oil.   
         o Maintenance and Insurance
         o Labor  -  will require trained operators and a qualified plant manager
               # Assumed staff work during 91 day salmon season and a 15 day start up and 15 day shut down period.
         o Estimated non-recoverable salmon season wastes (e.g., bone and non-salmon fish processed during salmon season) at 5% of total salmon waste 
   * Size byproducts plant for the average lb/day in the highest month of the peak year, assuming it operates 20 hours per day. 
   * Assumed byproduct plant operates only during salmon season. At other times waste volume is too small to run the plant and screened waste must be hauled for offshore disposal. 
         o Pumps and screens are operated whenever the processing plant operates
         o During salmon season, screened solids are transferred to the recovery  plant
         o During salmon season, wastes that may contain stainless steel hooks are diverted from the recovery plant and transferred to the disposal vessel
         o At other times, all screened solids are transferred to the disposal vessel 
Processing Location Assumptions
   * Facility-specific costs were estimated for processing plants for which EPA received a questionnaire response. This includes plants in five processing locations: 
         o Ketchikan, Petersburg, Juneau, Cordova, and the Kenai Peninsula. 
   * Concept level costs were estimated for model plants. Concept level model plant costs were developed to represent processing plants for which EPA did not receive a questionnaire:
         o Ketchikan: Alaska General Seafood (but not Pacific Sun),
         o Juneau: Taku Fisheries, 
         o Sitka: North Pacific and Seafood Producers Coop (but not Silver Bay)
         o Kenai Peninsula: Polar Seafoods, Sea Level Seafoods, Pacific Star, Salmantof, City of Homer/Fish Factory (but not Kenai Landing or Deep Creek)

Ketchikan 
   * If Ketchikan becomes "non-remote," Alaska General Seafoods and Trident Cannery will incur costs only for new flow meters and effluent monitoring.
         o For these plants, costs for Scenario 1 and 2b will be the same.
         o EPA estimated facility specific costs for the Trident Cannery and used those costs for the Alaska General Seafoods plant 
   * Under Scenario 1, Trident Norquest will continue to separate food grade waste, install a rotary screen, and transfer as much salmon waste as possible to APR. Norquest will purchase and operate a waste boat for non-salmon season waste (the cannery only operates during salmon season).
   * Under Scenario 1, E.C. Phillips will continue to separate food grade waste, install a rotary screen, and purchase and operate a waste boat for non-food grade salmon waste and non-salmon waste. 
   * For Scenario 2b, assumed APR will take all Ketchikan salmon waste generated during salmon season (E.C. Phillips, Trident Norquest, and Pacific Sun, if it is operating)
         o  All plants will cooperate in operating a boat for off shore waste disposal during salmon season and also during non-salmon season
         o Costs for buying and operating the boat will be allocated based on the amount of waste generated by each plant
         o Because Trident Cannery (and Alaska General) already haul waste, their Scenario 2b boat costs will be zero
Petersburg 
   * Ocean Beauty (OB) will continue to operate and will operate during salmon season, only
   * Icicle will maximize the use of its existing byproduct plant 
         o Icicle will not take OB or Trident waste
         o Icicle will incur costs to haul its residual waste, in any scenario, but not costs for a new screen or waste transfer pumps, because they already have a screen
         o Icicle will incur costs for a hopper, moving its grinder pump so it can be used to transfer waste to the disposal vessel, screened wastewater sump, and discharge pumps
         o Icicle will incur costs for a new flow meter and for effluent monitoring 
         o Icicle Scenario 1and 2b costs will be the same
   * In Scenario 2b, Trident and OB will build a combined byproducts plant. 
         o Both Trident and OB will transport their screenings from the processing plant to the byproducts plant 
         o Trident and OB will cooperate in hauling salmon season residuals. Trident will also haul non-salmon season residuals (when OB is not operating)
Juneau 
   * In Scenario 1, AK Glacier has costs for screening and monitoring, but no new costs for hauling their waste off shore because they already own and operate a boat. 
   * In Scenario 2b, AK Glacier and Taku will build a combined byproducts plant. 
         o Assumed neither has a building or land available
         o Costs and profits will be allocated based on the amount of waste processed 
         o The AK Glacier Scenario 2b financial impacts will be used to model impacts on Taku
Cordova 
   * Trident North (Cannery) will incur costs only for a new flow meter and effluent monitoring if Cordova becomes "non-remote." 
         o Costs for Scenario 1and 2b will be the same for the Trident Cannery.
   * Trident will maximize the use of its existing byproduct plant for Trident North and South waste. 
   * Under Scenario 1, Trident South will screen, separate food grade waste and transfer as much salmon waste as possible to Trident North recovery plant. Trident South non-recoverable waste will be disposed of at sea: Under Scenario 1, Trident South will purchase and operate a waste disposal boat. Under Scenario 2b, they use the cooperative boat.  
   * Under Scenario 1, Trident North will take OB and Copper River food grade heads  
         o OB and Copper River will screen and haul the rest of their waste
         o Each plant will purchase and operate its own waste disposal boat
   * Under Scenario 2b, OB and Copper River will send all of their waste to the Trident recovery plant. 
         o Trident, OB, and Copper River will cooperate in hauling residuals for off shore disposal during salmon season and also during non-salmon season
Sitka
   * Facility specific costs for E.C. Phillips are used to model costs for North Pacific and facility specific costs for Trident NorQuest, Ketchikan are used to model costs for Seafood Producers Coop. Model plant costs for the Silver Bay plant in Sitka; this plant was analyzed qualitatively
   * Assumed Absolute Fresh Seafoods is not operating: no costs or financial impacts
Kenai Peninsula
   * Seward and Kenai were analyzed as one processing location
   * Icicle Seward will maximize the use of its existing byproduct plant
         o Icicle will not take waste from any other plant
         o Icicle will incur costs to haul its residual waste, in any scenario, but not screening costs because they already have a screen. 
         o Icicle will incur costs for a hopper, moving its grinder pump so it can be used to transfer waste to the disposal vessel, screened wastewater sump, and discharge pumps
         o Icicle will incur costs for a flow meter and effluent monitoring
         o Icicle Scenario 1 and 2b costs will be the same
   * Inlet Fish Producers has NPDES permits for three locations on the Kenai Peninsula. Inlet operates seafood processing at two of these locations. For the purpose of estimating costs, EPA assumed 
         o all of Inlet's production occurs at one location. 
         o all of Inlet's costs for compliance with non-remote ELGs would be incurred at one location.
   * In Scenario 2b, EPA assumed all operating plants take their waste to the Scientific Fisheries/Alaska Marine Nutrition byproducts plant at Kenai Landing
         o EPA estimated costs for Inlet, Snug Harbor and Ocean Beauty and will estimate financial impacts
         o EPA assumed they will all cooperate in purchasing and operating a waste disposal boat
               # Boat size and operating costs were based on total processing location waste
               # Costs were allocated to Inlet, Snug Harbor, and OB based on their portion  of  the total Kenai Peninsula waste generation rate (without Icicle)
Dutch Harbor
   * EPA did not estimate costs for Dutch Harbor plants because as described below have management operations in place that allow them to meet the non-remote ELG requirements.
   * Dutch Harbor differs from all of the other processing locations in this analysis. Approximately 90 percent of their production is pollock; most of the remainder is crab, with a small amount of other fish. This mix of production affects the amount of waste generated and thus the size, design, and cost of facilities to screen and manage screened solids
   * Dutch Harbor production is dominated by three large processors
         o Alyeska
         o Westward
         o Unisea 
   * The three large processors (100  -  200 million pounds/year per plant)
         o operate close to year-round 
         o have individual NPDES permits with TMDL-based limits
         o operate onsite byproducts recovery plants for much (but not all) of their waste, notably producing fish oil used as biodiesel for on-site power generation to operate the processing plant 
         o screen their wastewater with a 0.5 mm mesh screen
         o haul some stickwater for off shore disposal during peak season in order to meet their BOD5 discharge limit 
   * Two Icicle barges are towed to Dutch Harbor for the pacific cod/pollock season
         o neither vessel screens or has a byproduct plant. 
         o they discharge under the general permit for near shore (0.5 - 1 mile off shore) vessels. 
         o they grind waste to 0.5 inch prior to discharge.
         o costs were not developed primarily because these facilities have operated intermittently 
   * One smaller producer Harbor Crown Seafoods/ Bering Star Fisheries (14 - 15 million pounds/year)
         o recently reopened under new ownership (Copper River is a part owner)
         o grind and discharge under the general permit.
         o costs were not developed primarily because this facility began operating after the time period for which EPA gathered and analyzed data  
EPA slightly refined the cost estimates used to model the financial impacts of facilities for which EPA did not collect detailed financial information (see Section 5 of this outline). The refinements included adjustments to the model plant costs to more accurately reflect the likely costs for the processors which did not receive a survey questionnaire.  Use of these costs for model plants is discussed in Report to the Record, Costs and Economic Impact Analysis for Alaska Seafood Processors (Facilities and Firms) DCN 00428.

EPA COLLECTED INFORMATION ABOUT THE COSTS FOR ALASKAN SEAFOOD PROCESSORS TO INSTALL AND OPERATE WASTEWATER POLLUTION CONTROL TECHNOLOGIES, INCLUDING BYPRODUCT RECOVERY PROCESSES AND HAULING WASTE FOR OFF-SHORE DISPOSAL. EPA'S PLANS FOR COLLECTING THESE DATA ARE DESCRIBED IN SECTION 2.4.2.2, POLLUTION CONTROL TECHNOLOGY COSTS, OF QUALITY ASSURANCE PROJECT PLAN: SUPPORT FOR EPA RESPONSE TO INDUSTRY PETITION ON ELGS FOR NON-REMOTE ALASKAN SEAFOod Processors, August 2013 (QAPP). QAPP Table 2-3 presents the criteria EPA planned to use to evaluate the quality of collected data. 
EPA used the Pollution Control Technology Cost Data Check List from QAPP Appendix B to document how the collected data met the cost data acceptance criteria. Checklist findings were recorded in a spreadsheet, a copy of which is presented in this Appendix. 
EPA's verification of how well the cost data met the quality specifications is presented, by acceptance criterion, in Section 3.1 of this memorandum.

DATE:	August, 2013

SUBJECT:	Direct and Indirect Escalation Cost Factors for Developing Budgetary Estimates for Waste Management at Seafood Processing Facilities

EPA is using a listing of the direct and indirect cost factors used to escalate the budgetary cost estimates for seafood processing facilities in Alaska. The direct cost escalation factors are for costs such as plumbing and electrical work that are added to the cost of purchased equipment to develop an installed equipment cost. Indirect costs are for engineering, scheduling, and other costs that are added to the installed capital cost to cover the contractor's overall project costs.  
Direct and Indirect Cost Escalation Factors
To estimate the installed capital cost for seafood waste management systems, EPA used the direct and indirect escalation factors shown in Tables 1 and 2 respectively. The factors in Table 1 were developed from U.S. Department of Defense construction programs and from project team experience with construction costs for various industrial sectors. The factors in Table 2 were developed taken mainly from RSMeans Construction Cost data supplemented with information from U.S. Department of Defense construction programs.  The specific references and/or sources of the escalation cost factors used to develop capital costs for seafood processing waste management systems are included in Tables 1 and 2.  
In general, EPA developed the escalation cost factors for plumbing, electrical, mechanical systems, and site preparation from projects related to construction activities at naval industrial facilities. These projects require moving liquids and sometimes semi-solids between various processing steps, similar to seafood waste management. The escalation cost factors have been tested on completed naval construction projects. For example, EPA used these escalation cost factors to prepare a conceptual cost estimate for a water treatment facility at a naval steam generating plant. EPA estimated the conceptual installed capital costs to be $12.8 million dollars for the water treatment facility, and the actual bids received from the construction company hired to build the water treatment facility were $12 million.  
The direct cost escalation factors in Table 1 are comparable to the factors presented in RSMeans. For example, in RSMeans the total mechanical and electrical cost escalation factor for an industrial factory ranges between 21 percent and 35.5 percent. EPA used 33.3 percent (17.5 + 15.8) for mechanical and electrical systems at the seafood processing waste treatment systems. According to RSMeans, the site work cost escalation factor for an industrial factory ranges between 6.95 percent and 17.95 percent. EPA used a cost escalation factor of 14 percent for the seafood waste management facilities. The plumbing cost escalation factor used by EPA for the seafood waste management facilities is outside the RSMeans published range for an industrial factory (3.7 percent to 8.1 percent), however EPA believes that because the majority of the process equipment associated with the seafood waste management requires plumbing systems similar to the Naval facilities, using the plumbing factor that somewhat higher than the RSMeans range is appropriate.

Seafood Waste Treatment Cost Methodology
In general, EPA obtained costs for seafood waste management equipment (e.g., rotary screens, pumps, tanks, etc) from vendors or from published literature, and applied the appropriate direct cost escalation factor percentage (e.g., electrical, plumbing, etc) to equipment cost to derive an installed capital cost. Not all of the Table 1 factors are applicable to each piece of equipment. For example, EPA did not apply the mechanical systems factor to pumps because the pumps will be installed in an existing structure with adequate supports and anchors and the pumps do not require duct work or HVAC. Similarly, EPA did not apply the instrumentation or site work factors because they are not required for pump installation. The example below shows how the direct cost escalation factor percentages were applied to the quoted price for a pump to derive an installed cost.
Pump Quoted Price:  $10,000
Pump Plumbing Cost @ 13.3% Escalation = $10,000 x (13.3/100) = $1,330
Pump Electrical Cost @ 15.8% Escalation = $10,000 x (15.8/100) = $1,580
Installed Pump Cost:  $10,000 + $1,330 + $1,580 = $12,910
EPA applied the individual indirect cost escalation factors shown in Table 2 to the installed capital costs to estimate a total indirect cost. The example below shows how indirect costs were estimated using the example for the pump.  
Installed Pump Cost:  $12,910
Pump Engineering Cost @ 8% Escalation = $12,910 x (8/100) = $1,032
Pump Permits Cost @ 2% Escalation = $12,910 x (2/100) = $258
Pump Scheduling Cost @ 0.8% Escalation = $12,910 x (0.8/100) = $103
Pump Performance Bond Cost @ 2.5% Escalation = $12,910 x (2.5/100) = $323
Pump Insurance Cost @ 2.0% Escalation = $12,910 x (2.3/100) = $258
Pump Contractor Mark-up @ 10% Escalation = $12,910 x (10/100) = $1,291
Pump Contractor Overhead and Profit @ 10% Escalation = $12,910 = $1,291
The total indirect cost is the sum of the engineering, permits, scheduling, performance bond, insurance, markup, and overhead and totals $4,556. The total installed capital cost for the pump is the total of the direct costs and indirect costs and is show below: 
    Total Installed Capital Cost for the Pump:  $12,910 + $4,556 = $17,466
Based on the direct and indirect cost factors used by EPA, the total installed capital cost is approximately 1.75 times the purchase price for the actual equipment.
