Re: Approval of Puget Sound Clean Air Agency's Request for Updated Delegation of Authority 

for National Emission Standards for Hazardous Air Pollutants 

Dear Mr. Kenworthy: 

This letter is in response to your letter requesting to update and continue the delegation of the 

National Emission Standards for Hazardous Air Pollutants (NESHAPs). Consistent with the 

approved mechanism for streamlined delegation as described in 63 FR 66054, 66057 (December 

1, 1998), the U.S. Environmental Protection Agency (EPA) hereby grants this updated delegation 

request, as described below, to the Puget Sound Clean Air Agency (PSCAA) for the identified 

NESHAPs in effect on July 1, 2012. 

Delegation Request 

You requested on November 29, 2012, to update delegation of the 40 CFR 61 and 63 standards 

that were previously delegated to PSCAA and to obtain delegation of new standards that the 

EPA has promulgated since your last delegation request as follows:

HHHHHHH. 

PSCAA has demonstrated that the above-referenced new and updated standards were adopted 

unchanged into PSCAA's Regulation I Section 3.25 on September 27, 2012. 

Delegation Authority 

The EPA has determined that PSCAA's regulations continue to provide adequate and effective 

procedures for implementing and enforcing the NESHAPs. Accordingly, the EPA hereby 

approves your request for an updated delegation of authority to implement and enforce the 

NESHAPs identified in Enclosure A, subject to the following terms and conditions: 

1. The EPA is delegating the identified federal standards as in effect on July 1, 2012. New 

NESHAPs or NESHAPs that are revised substantively after that date are not delegated to 

your agency; these remain the responsibility of the EPA. 

a. Acceptance of this delegation does not commit your agency to request or accept 

delegation of future NESHAPs and requirements. 

b. The EPA encourages your agency to update your NESHAP delegation on an 

annual basis. This could coincide with the updating of the adoption by reference 

of the Federal NESHAP standards, which is important for maintaining EPA 

approval of your Title V operating permit program. 

2. The EPA is not delegating authorities under 40 CFR Parts 61 and 63 that specifically 

indicate they cannot be delegated, that require rulemaking to implement, that affect the 

stringency of the standard, or where national oversight is the only way to ensure national 

consistency. Note that on June 23, 2003, the EPA published a rulemaking clarifying the 

authorities in each existing 40 CFR Part 63 NESHAP that can and cannot be delegated to 

state and local agencies. See 68 FR 37334 (June 23, 2003). Provisions of 40 CFR Part 63 

that are specifically identified in 68 FR 37334 as provisions that cannot be delegated to 

state and local agencies are not delegated to PSCAA. 

3. This delegation is subject to the terms and conditions of the EPA's previous NESHAP 

delegations to PSCAA, 63 FR 66054 (December 1, 1998), 64 FR 7793 (February 17, 

1999), 65 FR 10391 (February 28, 2000), 66 FR 14320 (March 12, 2001), 67 FR 11417 

(March 14, 2002), letters dated November 16, 2004, March 8, 2005, November 22, 2005, 

December 18, 2006, January 11, 2008, February 4, 2008, November 14, 2009, March 10, 

2011, and January 12, 2012.

0 Prtntecl on Recycled Paper 
4. The EPA is not delegating the following Subparts of Part 63: 

a. Consistent with your delegation request, Subpart S and MM with respect to kraft 

and sulfite pulp mills as described in PSCAA's Regulation III, Section 2.02; 

b. Subpart M for the reasons described in the EPA's letter dated January 11, 2008; 

and 

c. Subpart DDDDD (Industrial, Commercial and Institutional Boiler and Process 

Heaters), because the EPA has made significant amendments to this rule since it 

was published on July 1, 2012. 

5. This delegation is subject to all federal laws and regulations as well as the EPA policies, 

guidance, and determinations issued pursuant to 40 CPR Part 61 and Part 63. 

6. If both a state or local regulation and a federal regulation apply to the same source, both 

must be complied with, regardless of whether one is more stringent than the other, 

pursuant to the requirements of section 116 of the Clean Air Act. 

7. Implementation and enforcement of the delegated NESHAPs are subject to the current 

Compliance Assurance Agreement for Air Quality signed by PSCAA and the EPA. This 

agreement defines roles and responsibilities, including timely and appropriate 

enforcement response and the maintenance of the Aerometric Facility Subsystem (AFS). 

8. Enforcement of these delegated NESHAPs in your jurisdiction will be the primary 

responsibility of your agency. Nevertheless, the EPA may exercise its concurrent 

enforcement authority pursuant to section 113 of the Clean Air Act with respect to 

sources which are subject to the NESHAPs. 

9. Your agency and the EPA should communicate sufficiently to ensure that each is fully 

informed and current regarding interpretation of regulations (including any unique 

questions about applicability) and the compliance status of subject sources in your 

jurisdiction. 

a. Any records or reports provided to or otherwise obtained by your agency should 

be made available to the EPA upon request. 

b. In accordance with 40 CPR 61.16 and 63.15, the availability to the public of 

information provided to or otherwise obtained by the EPA in connection with this 

delegation shall be governed by 40 CPR Part 2. 

10. Your agency will be the recipient of all notifications and reports and be the point of 

contact for questions and compliance issues for these delegated NESHAPs. The EPA 

may request notifications and reports from owners/operators and/or your agency, if 

needed.

11. Your agency will work with owners and operators of affected facilities subject to a 

NESHAP Subpart to ensure all required information is submitted to your agency. We 

request your assistance to ensure that this information - including excess reports and 

summaries -is submitted to the EPA upon request. 

12. Your agency will ensure that all relevant source notification and report information is 

entered into the AFS database system to meet your recordkeeping/reporting requirements. 

The AFS reporting elements for "source information" that your agency is expected to 

provide include, but are not limited to: 

a) Identification of source 

b) Pollutants regulated 

c) Applicability of subparts 

d) Permit number for specific source or sub-unit 

e) Dates of most recent NESHAP compliance evaluations (inspections) 

f) Compliance status 

13. Your agency will require affected facilities to utilize the methods specified in 40 CFR 

Part 61 and 63 in performing source tests pursuant to the regulations. See 40 CFR 63.7. 

14. Changes and alternatives: 

a. Your agency is not delegated authority to approve "major changes to test 

methods," "major changes to monitoring," "major changes to 

recordkeeping/reporting," equivalent methods, alternative methods, emerging 

technologies, equivalent means of emission limitations, petitions for exemptions, 

and time extensions. Such approvals remain the responsibility of the EPA. 

b. Approval of "minor changes to test methods," "intermediate changes to test 

methods," "minor changes to monitoring," "intermediate changes to monitoring," 

and "minor changes to recordkeeping/reporting" is delegated to your agency. 

c. Your agency must maintain a record of all approved alternatives to monitoring, 

testing, recordkeeping/reporting requirements and provide this list of alternatives 

to the EPA semi-annually or more frequently if requested by the EPA. The EPA 

may audit any approved alternatives and disapprove any that it determines are 

inappropriate, after discussion with your agency. If changes are disapproved, your 

agency must notify the owner/operator that it must revert to the original 

applicable monitoring, testing, recordkeeping, and/or reporting requirements. 

Also, in cases where the owner/operator does not maintain the conditions which 

prompted the approval of the alternatives to the monitoring, testing, 

recordkeeping, and/or reporting requirements, your agency must require the 

source to revert to the original monitoring, testing, recordkeeping, and reporting 

requirements, or more stringent requirements, if justified.

d. For purposes of this paragraph, the terms in quotations have the meaning assigned 

to them in 40 CFR 63.90. 

15. Your agency's authority to implement and enforce the NESHAPs under this delegation 

does not extend to sources or activities located in Indian Country, as defined in 18 U.S.C. 

1151 . Consistent with previous Federal program approvals or delegations, the EPA will 

continue to implement the NESHAP in Indian Country in Washington because your 

agency did not adequately demonstrate authority over sources and activities located 

within the exterior boundaries of Indian reservations and in other areas of Indian Country. 

The one exception is within the exterior boundaries of the Puyallup Indian Reservation, 

also known as the 1873 Survey Area. Under the Puyallup Tribe of Indians Settlement Act 

of 1989, 25 U.S.C. 1773, Congress explicitly provided State and local agencies in 

Washington authority over activities on non-trust lands within the 1873 Survey Area. 

Therefore, this delegation approval allows your agency to implement and enforce the 

NESHAP on non-trust lands within the 1873 Survey Area. 

16. Your agency's authority to implement and enforce the NESHAP under this delegation 

does not extend to sources or activities under the jurisdiction of the Washington Energy 

Facility Site Evaluation Council (EFSEC). EFSEC has not requested an updated 

delegation. Therefore, the EPA retains the authority to implement and enforce the 

NESHAP over these specific sources. 

17. Based on an opinion letter from an attorney for your agency, the EPA has determined that 

the restriction on the issuance of civil penalties in Chapter 43.05 of the Revised Code of 

Washington, often referred to as "House Bill 1010," does not apply to local air authorities 

in Washington. 

18. The EPA Administrator delegated to the EPA Region 10 the authority to delegate the 

NESHAPs to any state or local agency. A state or local agency that receives delegation 

from the EPA Region 10 does not have the federally recognized authority to further 

delegate the NESHAPs. 

19. If the EPA determines that your agency's procedures for implementing or enforcing the 

NESHAPs are inadequate or are not being effectively carried out, this delegation may be 

revoked in whole or in part by written notice of the revocation. Any such revocation will 

be effective as of the date specified in the notice.

Unless we receive negative comments from you within ten (10) days, this delegation is final and 

will be effective ten (1 0) days from the date of this letter. Otherwise, no further correspondence 

to the EPA is needed from PSCAA to make this delegation effective. We will periodically 

publish a notice in the Federal Register informing the public ofPSCAA's updated delegation. 

If you have any questions regarding this approval, please contact Davis Zhen of my staff at 

(206) 553-7660 or email at zhen.davis@epa.gov.
