Dear Mt·. Gustafson: 

RE: Automatic Delegation of Clean Air Act (CAA) Section 111 

Requirements 

This letter is to notify you of the EPA Region 8's intention to automatically delegate the CAA section 

111 Standards of Performance for New Stationary Sources, 40 CFR part 60 standards, also known as 

New Source Perfonnance Standards (NSPS) to your state. The letter also provides infonnation about the 

statutmy basis for automatic delegation of section 111 standmds and outlines a communication protocol 

that should be followed regarding the adoption of these standards. 

Section lll(c) and an approved part 70 operating permits (title V) program authorizes states to receive 

automatic delegation of section Ill standards if the federal standards are incorporated by reference 

(IBR). The title V program approval is a demonstration that the state has the ability to implement and 

enforce existing section 111 standards and a commitment to implement and enforce future standards to 

assure the timely issuance or revision of part 70 permits. The EPA approved South Dakota's title V 

program on January 29, 1996 (61 FR2720). 

Similar to the automatic delegation for National Emission Standards for Hazardous Air Pollutants 

(NESHAPs) currently used by South Dakota, automatic delegation of the NSPS is only permissible if 

the NSPS are IBR into the South Dakota Administrative Rules (SDAR). The state then has delegation 

automatically to implement and enforce those standards for affected sources when the NSPS are 

incorporated unchanged into the SDAR. The date of delegation would be the date the standards are 

effective in the SDAR. If South Dakota adopts an NSPS but chooses not to accept delegation of the 

NSPS, you should notify us prior to the first compliance date. It is important to note that if South 

Dakota changes an NSPS in any way, then the standard would not be automatically delegated and 

formal case-by-case approval and delegation must occur. Until approval occurs, the EPA remains the 

implementing and enforcing authority. 
States also have the option of receiving partial delegation of an NSPS. The procedures for automatic 

partial delegation of severable portions of any NSPS are as follows: 1) the state must clearly define the 

separable subcategory in the particular NSPS or the specific separable subset of affected sources in the 

specific NSPS so regulated sources and the public know who is the implementing and enforcing 

authority; and 2) the applicable portions of the federal NSPS must be adopted by IBR into the state 

regulations or rules with a clear explanation of what is included and what is not incorporated into the 

state rule. 

To avoid confusion, it is essential for the EPA and South Dakota to keep an accurate record of the 

primary enforcement authority for each NSPS. Toward that end, we request that you notify the EPA 

within 60 days of incorporating an unchanged NSPS into state rules. The notification should include an 

official copy of the standard that is stamped, dated and signed by the appropriate official. The official 

copy should also include the date of adoption and the effective date. If there is a change in the schedule 

for the NSPS becoming effective, then the state should notify the EPA as soon as possible. If the delay 

extends beyond the standard's compliance date, the EPA will implement and enforce the standard until 

the state has an effective standard. The EPA will meet the requirement for public notification for 

delegation ofNSPS via a webpage on the Region 8 website at www2.epa.gov/region8/air-program. The 

EPA will notify the public in a Federal Register Notice that future delegation updates will be provided 

on the Region 8 website and that the website will replace the Federal Register Notice. 

Please note there are some section Ill standards that may not be automatically delegated to a state. The 

section Ill requirements found in 40 CFR part 60 subparts Cb, Cc, Cd, Ce, BBBB, DDDD, FFFF and 

MMMM are emission guidelines that require state plans and are approved under a separate process 

pursuant to section 111 (d) of the CAA. In addition, some portions of the section Ill standards and their 

associated general provisions, by their own terms, may not be delegated to a state. The EPA 

Administrator retains authority to implement those sections that require: 1) approving equivalency 

determinations and alternate test methods; 2) decision-making to ensure national consistency; and 3) 

EPA rulemaking in order to implement. Enclosure I with this letter is a list of example sections in 40 

CFR part 60 that may not be delegated. Accordingly, the EPA is retaining authority over those portions 

of the CFR part 60 standards that may not be delegated. 

Enforcement of the delegated section Ill standards within the state would be the primary responsibility 

of the South Dakota Department of Environment and Natural Resources (SDDENR). If the SDDENR 

determines that such enforcement is not feasible and so notifies the EPA, or where SDDENR acts in a 

manner inconsistent with the terms of this delegation, the EPA may exercise its concurrent enforcement 

authority pursuant to section 113 of the CAA, as amended, with respect to sources within the state of 

South Dakota, excluding Indian country, subject to section 111 standards. 

The automatic delegation of NSPS that have been IBR and have not yet been delegated to South Dakota 

will be effective on February 27, 2014, as indicated in Enclosure II. If you do not want to use automatic 

delegation retroactively for any outstanding NSPS delegations, then provide a list ofNSPS that have 

been adopted and that you want excluded from the automatic delegation process within 30 days of 

receipt of this letter. Please note that an NSPS delegation request should not be included in a State 

Implementation Plan (SIP) submittal because the automatic delegation procedure is replacing requests 

for NSPS delegation. 
If you have questions about our action or the delegation process, please contact me directly at (303) 312-

6416 or your staff can contact Victoria Parker-Christensen, Air Program, at (303) 312-6441 or
