IN THE MATTER OF: 

### ? 

## 1 State implementation Plan Approval ) Regional Haze

## - Class I Area Visibility Impairment ) ORDERNO. 08-003



### BOARDORDER

The Board finds that Tennessee is required to submit 

### a state implementation plan (SIP) to the United States Environmental Protection Agency (USEPA) that addresses the protection and improvement of visibility in Class I areas that may be significantly impacted by visibility impairing emissions fiom Tennessee. The USEPA enacted regulations detailing this requirement fiom its statutory mandate under sections 169A, 169B, and 1lO(a)(2)(J) of the Clean Air Act. Those regulations are specified at 40 CFR 51.308.

As authorizedby the Board, Tennessee participated in a regional planning organizationof ten southeastern states known as VISTAS (Visibility Improvement State and Tribal Association of the Southeast). The mission of VISTAS 

### was to prepare the science component of the SIP that establishes baselines and demonstrates that certain goals and deadlinesrequired by federal regional haze regulations are likelytobe met.

On April 4, 2008, the regional haze SIP prepared by the Tennessee Department of Environment and Conservation's Division of Air Pollution Control (staff) was presented to the Board for frnal review, adoption and forwarding to the USEPA with a request for federal approval. Among other things, the Board 

### was provided the pubIic comments received in regard to the SIP and a staff prepared comment summary of two public participation hearings relative to the regional haze SIP.

I The Board finds that the staffhas conferred with the federal land managers administering Class 

### I areas that may be impacted by visibility impairing pollutants fiom Tennessee. The Board also recognizes that the Tennessee Regional Haze SIP includes four sourcespecific SIP revision permits that establish BART (Best Available Retrofit Technology), a program to require source specific emission limits for certain existing major sources that emit visibility impairing pollutants. The Board understands that these permits contain only conditions that relate to BART and that upon federal approval, the source specific permit will be incorporated into the source's major source operating permit consistent with the reopening provisions under Tennessee Rule 1200-3-9-.02(11) that correspondsto federal regulations at 40 CFR Part 70.While there are four BART permits in the Tennessee Regional Haze SIP that have been issued by the Board's Technical Secretary, the Board recognizes that the permit for one BART source -the Dupont facility in Old Hickory, Davidson County, Tennessee, will be ultimately incorporated into a major source operating permit issued by the Metropolitan Davidson County Department of Public Health. That local government agency operates under a TCA 68-201-1 15 Certificate of Exemption previously issued by the Board. Until that local government action occurs, the Board instructs the staff to enforce the permit as one of its own.
Upon recommendation by the staff for approval, the Board adopts the Tennessee Regional Haze SIP for incorporation into the Tennessee State Implementation Plan and formally requests the USEPA to approve it as 

### part of the federally approved SIP for Tennessee.

Entered and approved on this the fourth day of April, 2008 by the following Board members:
