Part B. General Applicability

1. This standard will apply to existing processes statewide except in the following six counties: 

Anderson, Bamberg, Barnwell, Chesterfield, Darlington and Hampton.

2. This standard will apply to plants described under one of the Parts of Section II when such a plant 

has total potential emissions of VOC more than 550 pounds (250 kilograms) in any one day (nominal size 

- 100 tons per year) or more than 150 pounds (68 kilograms) in any one hour. This paragraph does not 

apply to Part N.

subject to the Regulation when that plant increases emissions sufficiently to meet the applicability 

requirements regardless of the time frame. Conversely, a source which is subject to the requirements of 

the Regulation, but which decreases emissions sufficiently so that their total potential emissions are below 

the applicability requirements, may petition the Department for relief from the emission limits of the 

Regulation. Approval of the petition will be based, in part, on a showing that the reductions are not 

temporary and a consent to be permitted at the reduced level.

4. Further applicability requirements or limitations may be listed under the individual Parts of

Section II.

Part C. Alternatives and Exceptions to Control Requirements

1. Alternative Controls

a. If the owner or operator of a source of volatile organic compounds regulated by this Standard 

can demonstrate that compliance with Section II would not be feasible, he may petition the Department to 

allow the use of alternative operational and/or equipment controls for the reduction of volatile organic 
October 26, 2001 62.5, St. 5 - Page 7

compound emissions of such source. Petition must be made for each source within a given plant and 

nothing herein should be interpreted as permitting a source regulated by this Standard to exceed emission 

limits for that source as given in Section II. The petition must be submitted in writing to the Department 

and must contain:

(i) the name and address of the company and the name, address and telephone number of a 

company officer over whose signature the petition is submitted; and,

(ii) a description of all operations conducted at the location to which the petition applies and the 

purpose that the volatile organic compounds emitting equipment serves within the operations; and,

(iii) reference to the specific operational and/or equipment controls under Section II for which 

alternative operational and/or equipment controls are proposed; and,

(iv) a detailed description of the proposed alternative operational and/or equipment controls, the 

magnitude of volatile organic compound emission reduction which will be achieved, and the quantity and 

composition of volatile organic compounds which will be emitted if the alternative operational and/or 

equipment controls are instituted; and

(v) a schedule for the installation and/or institution of the alternative operational and/or

equipment controls in conformance with Section II. 

b. The Department may approve a Petition for Alternative Control if:

(i) the petition is submitted in accordance with paragraph a above; and,

(ii) the Department determines that the petitioner cannot comply with Section II because of 

technological infeasibility (considering costs); and,

(iii) the petition contains a schedule for achieving and maintaining reduction of volatile organic 

compound emissions to the maximum extent feasible and as expeditiously as practicable; and,

(iv) a nuisance condition will not result from operation of the source as proposed in the Petition; 

and,

in the appropriate part of Section II.

(vi) the petition is approved by U.S.E.P.A. as a source-specific State Implementation Plan 

revision.

2. Alternative Emission Limitations

a. If the owner or operator of a source of volatile organic compounds regulated by this standard can 

demonstrate that compliance with applicable portions of Section II would not be economically feasible, 

the Department may, on a case-by-case basis, allow emission limitations less stringent than those required 

by applicable parts of Section II.

All data pertinent to the showing of economic infeasibility must accompany a petition for this relief, 

and shall include a present value analysis showing economic infeasibility.
October 26, 2001 62.5, St. 5 - Page 8
