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

Requirements

Dear Mr. Klemp:

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

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

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

statutory basis for automatic delegation of section Ill standards 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 111 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 Montana's title V final

program on June 13,2000 (65FR37049).

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

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

NSPS are IBR into the Administrative Rules of Montana (ARM). The state then has delegation

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

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

effective in the ARM. If Montana 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 Montana 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 Montana 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 111 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 111 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 111 standards within the state would be the primary responsibility

of the Montana Department of Environmental Quality (MTDEQ). If the MTDEQ determines that such

enforcement is not feasible and so notifies the EPA, or where the MTDEQ 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 Montana, excluding

Indian country, subject to section 111 standards.

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