SUPPLEMENTARY INFORMATION: In a letter dated August 14, 2019, EPA 
Region 1 suggested that CT DEEP and EPA Region 1 update the protocol 
for delegation of NSPS and NESHAPs and develop a delegation MOA between 
EPA Region 1 and CT DEEP. The MOA was signed by the Commissioner of CT 
DEEP on September 10, 2019 and was signed by the Region 1 Administrator 
on October 2, 2019. The MOA summarizes the approved delegation 
mechanisms, the procedures for delegation, and the conditions of 
delegation. The delegation mechanisms being used for delegation of 40 
CFR parts 60, 61, and 63 were previously approved by EPA Region 1 and 
have not changed, as described in more detail below in the MOA. The 
August 14, 2019 letter provided a list of previously delegated NSPS and 
NESHAPs, in order to reconfirm delegation of those standards. In 
addition, the letter provided a checklist for CT DEEP to complete and 
return to indicate its acceptance of delegation of subsequent standards 
in parts 60, 61, and 63 for Title V permitted sources, and to request 
delegation for parts 60 and 61 for all sources, including non-Title V 
permitted sources. The text of EPA Region 1 and CT DEEP's October 2, 
2019 MOA is reproduced below:

Memorandum of Agreement Between Connecticut Department of Energy and 
Environmental Protection (CT DEEP) and U.S. EPA Region 1 for Delegation 
of National Emissions Standards for Hazardous Air Pollutants (NESHAPs) 
and New Source Performance Standards (NSPS)

I. Delegation Mechanisms

    On April 23, 1999, EPA approved CT DEEP's delegation mechanism to 
accept delegation of the Clean Air Act (CAA) Section 111 and Section 
112 federal standards for sources that have obtained a CAA Title V 
operating permit. See 64 FR 19922. This Memorandum of Agreement (MOA) 
reconfirms the delegation mechanism approved in the April 23, 1999 
Federal Register notice for delegation of part 60 NSPS, part 61 
NESHAPs, and part 63 NESHAPs for Title V permitted sources upon 
issuance of the Title V permit incorporating the applicable standards 
for affected sources. EPA's April 23, 1999 approval referenced the 
delegation procedures in a letter dated October 7, 1996 from CT DEEP to 
EPA Region 1. This MOA revises the delegation procedures contained in 
the October 7, 1996 letter and provides revised conditions of 
delegation.
    CT DEEP can accept delegation of part 60 NSPS and part 61 NESHAPs 
for all stationary sources, including non-Title

[[Page 5575]]

V operating permitted sources, under the authority in 22a-174-9 of the 
Regulations of the Connecticut State Agencies (RCSA). This delegation 
mechanism was approved in a letter dated September 30, 1982 from EPA 
Region 1 to CT DEEP, was confirmed in a letter dated December 22, 1994 
from EPA Region 1 to CT DEEP, and was again confirmed in a letter dated 
November 8, 2018 from CT DEEP to EPA. This MOA reconfirms this 
delegation mechanism for part 60 NSPS and part 61 NESHAPs. In addition, 
this MOA revises the procedures and conditions of delegation contained 
in the September 30, 1982 letter.

II. Procedures for Delegation

    1. EPA Region 1 will provide an annual letter to CT DEEP with a 
checklist identifying the newly promulgated part 60 NSPS, part 61 
NESHAPs, and part 63 NESHAPs standards and amendments to standards 
which have been previously delegated.
    2. CT DEEP will complete the checklist and return it to EPA Region 
1 within 60 days of receipt of the checklist. For each standard, CT 
DEEP will indicate whether there are any affected sources in the State.
    3. CT DEEP will complete the checklist to indicate whether CT DEEP 
requests delegation of part 60 NSPS, part 61 NESHAPs, and part 63 
NESHAPs standards for affected sources subject to the Title V operating 
permit program. Delegation of a standard for a source subject to a 
Title V operating permit occurs upon issuance of the Title V operating 
permit incorporating the applicable standards for affected sources.
    4. CT DEEP will complete the checklist to indicate which new part 
60 NSPS and part 61 NESHAPs standards, if any, for which the CT DEEP is 
requesting delegation for all sources.
    5. Amendments to standards previously delegated will be 
automatically delegated, unless CT DEEP declines delegation in writing 
to EPA Region 1 within 60 days of receipt of the annual checklist.
    6. Upon receipt of the completed checklist, EPA Region 1 will issue 
a letter to the CT DEEP confirming delegation of the federal standards.
    7. EPA Region 1 will develop and maintain a list of delegated NSPS 
and NESHAPs on the EPA Region 1 website.

III. Conditions of Delegation

    1. CT DEEP will assume primary responsibility for enforcement of 
delegated NSPS and NESHAPs.
    2. CT DEEP will not grant a variance from compliance with 
applicable emission standards of NSPS and NESHAPs.
    3. CT DEEP will communicate with EPA Region 1 to keep each office 
fully informed regarding the current compliance status of subject 
sources in Connecticut and interpretation of applicable regulations.
    4. CT DEEP will require all NSPS and NESHAPs sources to adhere to 
the reporting, monitoring, and recordkeeping requirements specified in 
the NSPS and NESHAPs, except as may be modified through Title V 
streamlining or other approvals. CT DEEP will describe any Title V 
streamlining or alternatives to reporting, monitoring, and 
recordkeeping in the Title V Technical Support Document or in 
documentation concerning approvals for modifications of reporting, 
monitoring and recordkeeping for non-Title V sources.
    5. CT DEEP will issue applicability determinations that are routine 
in nature and will forward to EPA Region 1 any applicability questions 
that are unique or unusually complex. EPA Region 1 will provide 
technical assistance as necessary to the CT DEEP.
    6. EPA delegates only the authority to approve minor or 
intermediate alternatives to test methods and monitoring.\1\ EPA 
retains the authority to approve major alternatives to test methods and 
monitoring. CT DEEP must maintain a record of all approved alternatives 
to all monitoring, testing, recordkeeping, and reporting requirements 
and provide this list of alternatives to EPA Region 1 at least semi-
annually.
---------------------------------------------------------------------------

    \1\ Forty CFR part 63 subpart E, section 63. 91(g) specifies the 
part 63 subpart A authorities which may be delegated. In addition, 
the EPA document titled ``How to Review and Issue Clean Air Act 
Applicability Determinations and Alternative Monitoring'' (EPA 305-
B-99-004, February 1999) specifies that EPA may delegate the 
authority to issue minor or intermediate alternatives to test 
methods and monitoring for part 60 NSPS and part 61 NESHAPs. This 
guidance document and 40 CFR 63.90 provide definitions of minor, 
intermediate, and major alternatives to test methods and monitoring.
---------------------------------------------------------------------------

    7. CT DEEP will follow the process identified in 40 CFR 63.96(b) 
for returning delegation of part 61 NESHAPs or part 63 NESHAPs 
standards. CT DEEP will notify EPA Region 1 in writing if CT DEEP 
intends to return delegation of any part 60 NSPS and will coordinate 
with EPA Region 1 on the process required for returning delegation of a 
part 60 NSPS standard.
    8. CT DEEP will coordinate with EPA Region 1 on the process 
required in the event CT DEEP intends to pursue partial delegation of 
part 60 NSPS, part 61 NESHAPs, or part 63 NESHAPs standards.
    9. If the EPA Regional Administrator determines that CT DEEP is not 
adequately implementing or enforcing NSPS or NESHAPs, the Regional 
Administrator may revoke delegation of NSPS or NESHAPs in whole or 
part.
