(10) Copies of all records and reports required by subsection 22a-174-20(aa) must be kept at the source for a minimum of two years.
(bb) Compliance methods.
(1) The owner or "operator" of a "stationary source" subject to subsections (m) through (s) of Section 22a-174-20 inclusive, shall achieve the "emission" limit under the appropriate paragraph by:
(A) The application of low solvent content coating technology for each coating used; or
(B) Incineration, provided that a minimum of ninety (90) percent of the non-methane "volatile organic compounds" (measured as total combustible carbon) which enter the "incinerator" are oxidized to carbon dioxide and water per hour and where the overall required efficiency is determined pursuant to subdivision (bb) (3) or (bb) (4); or (C) A system demonstrated to have an hourly control efficiency equivalent to or greater than the above and approved by the "Commissioner" by permit or order.
(2) A capture system used in conjunction with the "emission" control systems in subparagraphs (bb) (1) (B) and (bb) (1) (C) of Section 22a-174-20 must be capable of collecting a minimum of ninety (90) percent of the "volatile organic compound" "emissions" from the "process source."
(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;

(D) Use an alternative means, achieving a level of control equivalent to subparagraph (A), (B) or (C) of this subdivision, as requested from and approved by the commissioner, in accordance with subsection (cc) of this section; or
(E) Limit the total potential VOC emissions from all pleasure craft coating operations and related cleaning by permit or order of the commissioner to 1,666 pounds or less in any calendar month.
(5) Application methods. Except as provided in subdivision (3) of this subsection, an owner or operator shall not apply a VOC-containing coating to a pleasure craft or to a part or component of a pleasure craft unless the coating is applied by one of the methods identified in subparagraphs (A) through (F) of this subdivision using equipment operated in accordance with the specifications of the equipment manufacturer:
(A) Electrostatic application;
(B) HVLP spray application;
(C) Airless spray application;
(D) Air-assisted airless spray application;
(E) Hand application; or
(F) Any other coating application method capable of achieving a transfer efficiency equivalent to or better than that provided by HVLP spray application. Any coating operation using an application method pursuant to this subparagraph shall maintain records demonstrating the transfer efficiency achieved.
(G) The requirements of this subdivision shall not apply to the application of an extreme high gloss coating.
(6) Work practices. Each owner or operator shall use the following work practices:
(A) New and used VOC-containing coating, diluent or cleaning solvent, including a coating mixed on the premises, shall be stored in a nonabsorbent, non-leaking container. Such a container shall be kept closed at all times except when the container is being filled, emptied or is otherwise actively in use;
(B) Spills and leaks of VOC-containing coating, diluent or cleaning solvent shall be minimized. Any leaked or spilled VOC-containing coating, diluent or cleaning solvent shall be contained, absorbed and removed immediately;
(C) Absorbent applicators, such as cloth and paper, which are moistened with a VOC-containing coating or solvent, shall be stored in a closed, nonabsorbent, non- leaking container for disposal or recycling; and
(D) VOC-containing coating, diluent and cleaning solvent shall be conveyed from one location to another in a closed container or pipe.
(7) Records.
(A) Except as provided in subparagraphs (B) and (C), an owner or operator shall maintain records of information sufficient to determine compliance with the applicable requirements of this subsection, including, at a minimum, the following information for each calendar month:
(i) Name and description of each coating and cleaning solvent,
(ii) VOC content of each coating and diluent, as applied, and the associated calculations,
(iii) VOC content of each coating or cleaning solvent, as supplied,
(iv) The amount of each coating and cleaning solvent:
(I) Purchased, or
(II) Used,
(v) A Material Safety Data Sheet, Environmental Data Sheet, Certified Product Data Sheet, or an equivalent data sheet for each coating and cleaning solvent,
(vi) Documentation of control device efficiency and capture efficiency, if applicable, using an applicable EPA reference method or alternate method as approved by the commissioner and the Administrator, and
(vii) Date and type of maintenance performed on air pollution control equipment, if applicable.
(B) All records made pursuant to this subdivision shall be:
(i) Made available to the commissioner to inspect and copy upon request, and
(ii) Maintained for five years from the date such record is created.
(8) Compliance procedures.
(A) The VOC content limits of Table 20(kk)-1 apply to the volume of coating as applied, determined using the following equation:

VOC Content = (Ws - Ww-Wes)/(Vm - Vw - Ves)

Where:

Ws = weight of volatile compounds in grams

Ww = weight of water in grams

Wes = weight of exempt compounds in grams

Vm = volume of coating in liters

Vw = volume of water in liters

Ves = volume of exempt compounds in liters

(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.
