(3) In cases where control technology is the selected compliance option, the minimum overall reduction of volatile organic compounds, required to demonstrate compliance with subsections (m) through (s) of Section 22a-174-20 inclusive, shall be the least stringent of the following:

(A) at least ninety-five (95) percent; or

(B) the amount necessary to reduce the hourly actual "volatile organic compound" emissions to less than the hourly allowable "volatile organic compound" emissions as determined in subdivision (6) of this subsection.

(4) If either the minimum capture system efficiency requirement or the minimum control efficiency requirement, specified above, cannot be reasonably demonstrated, the Commissioner may accept an averaged system efficiency provided the net emission rate is equal to or less than the emission rate which would result through compliance with the control system and capture system minimum efficiencies required by subdivisions (bb) (1) and (bb) (2) of Section 22a-174-20.

(5) Compliance proposals pursuant to subsection (cc) of Section 22a-174-20, alternative emission reduction plans, must utilize the calculation methods described by subdivision (bb) (3) of Section 22a-174-20 concerning solids-applied basis computations and the system efficiency requirements of subsections (bb) (1) (B) and (bb) (2) of Section 22a-174-20. For purposes of subsection (cc) of Section 22a-174-20, "allowable emissions" are based on the solids-applied basis emissions rather than the minimum required system efficiency. If the emissions after the application of control equipment, represent a greater net reduction of volatile organic compound emissions, the increased reduction may be used as a credit to offset excess emissions from non-conforming sources at the premise.

(6) To calculate hourly allowable "volatile organic compound" (VOC) emissions under subdivision (3) of this subsection, follow the steps in subparagraphs (A) through (D) below.

(A) Determine the discharge limit (in pounds of VOC per gallon of coating) for the surface coating operation in subsections 22a-174-20(m) through (s).

(B) Locate the discharge limit in the left hand column of Table 20 (bb)-1 below.

(C) Locate the corresponding emission limit (in pounds of VOC per gallon of solids) from the right hand column of Table 20 (bb)-1 below.

(D) Multiply the emission limit (in pounds of VOC per gallon of solids) by the hourly volume of solids applied (in gallons per hour) during the subject surface coating operation to yield the hourly allowable VOC emissions (in pounds per hour).

(cc) Alternative emission reductions.

(1) The owner or "operator" of a "stationary source" subject to the provisions of subsections (m) through (v) inclusive and (ee) may submit for the consideration of the "Commissioner" an alternative "emission" reduction plan which would achieve the same net "emission" reduction as the owner or "operator" would achieve by having each "emission" source comply with the prescribed "emission limitations" provided in these regulations. Approval of the alternative plan is discretionary with the "Commissioner," but at a minimum, the owner or "operator" of the "stationary source" must demonstrate that:

(A) by means of an approved material balance or acceptable "emission" test, sufficient reductions in "volatile organic compound" "emissions" will be obtained by controlling other existing emission sources of similar "volatile organic compounds" within the "stationary source" to the extent necessary to compensate for all excess "emissions" which result from one or more emission sources not achieving the prescribed "emission limitation." This demonstration must be submitted in writing and must include:

(i) A description of the emission source or "sources" which will not comply with the prescribed "emission limitations";

(ii) Pounds per hour of "volatile organic compounds" emitted which are in excess of permissible "emissions" for each emission source;

(iv) Pounds per hour of "volatile organic compounds", for each emission source both before and after the improvement or installation of any applicable control system, or any physical or operational changes at the facility to reduce "emissions" and the date on which these reductions will be achieved; and

(2) The implementation of an alternative emission reduction plan instead of compliance with the emissions limitation prescribed in any one of subsections (m) through (v), inclusive, (ee) or (ff) to (kk), inclusive, of this section shall be expressly approved by the commissioner through the issuance of a permit or an order in accordance with the provisions of section 22a-174-12 of the Regulations of Connecticut State Agencies and approved by the Administrator in accordance with the provisions of 42 USC 7401-7642. After approval, any emissions in excess of those established for each emission source under the plan will be a violation of these regulations.

(3) Where it can be shown to the satisfaction of the commissioner that an emission source cannot be controlled to comply with any one of subsections (m) through (v), inclusive, (ee) or (ff) to (kk), inclusive, of this section for reasons of technological and economic feasibility, the commissioner may by permit or order accept a lesser degree of control upon the submission of satisfactory evidence that the stationary source owner has applied Reasonably Available Control Technology and has a plan to develop the technologies necessary to comply with the applicable subsection of subsections (m) to (v), inclusive, (ee) or (ff) to (kk), inclusive, of this section and such action is approved by the Administrator in accordance with the provisions of 42 USC 7401-7642.

(B) The VOC emission rate limits of Table 20(kk)-2 apply to the mass of VOC emitted per volume of coating solids, as applied.

(C) To determine the properties of a coating or components thereof in order to perform the calculations required pursuant to subparagraph (A) of this subdivision or to verify calculations based on the manufacturer's formulation data, the VOC and solids content of all coatings shall be determined using 40 CFR 60, Appendix A, Reference Method 24 or an equivalent method. In the case of a dispute, the VOC content determined using Reference Method 24 shall control, unless a person is able to demonstrate to the satisfaction of the commissioner and the Administrator that the manufacturer's formulation data are correct.

(D) Where a VOC content limit or emissions rate is provided in metric units and equivalent English units, the limit or rate in metric units defines the standard. The English units are provided for information only.

(E) A pleasure craft coating shall be defined and categorized based on the manufacturer's representations as set out on the container or label or in information provided by the manufacturer of such a pleasure craft coating.
