Chapter 285 - Air pollution.
285.39 - Volatile organic compounds growth accommodation and replenishment.

285.39 Volatile organic compounds growth accommodation and replenishment.
(1) Growth accommodation calculation.
(a) The growth accommodation for any specified year, as calculated by the department, is the predicted emissions specified in par. (b) minus the sum of:
1. Net actual emissions specified in par. (c);
2. Net certified accommodation credits specified in par. (d);
3. Net offset credits specified in par. (e); and
4. Set asides specified in par. (f).
(b) Predicted emissions are the total predicted annual emissions of volatile organic compounds in the volatile organic compound accommodation area necessary to attain and maintain the ambient air quality standard for ozone for the year 2 years before the specified year, as set forth in the plan approved by the U.S. environmental protection agency under 42 USC 7502 (a).
(c) Net actual emissions are the total actual annual emissions of all volatile organic compounds in the volatile organic compound accommodation area for the year 2 years before the specified year as reported under sub. (2) (a) minus:
1. The sum of the annual emissions of volatile organic compounds attributable to shutdowns of facilities in the volatile organic accommodation area during the previous year; and
2. If a rule has been promulgated under sub. (3), the sum of the annual emissions reductions of volatile organic compounds attributable to the sources subject to the rule promulgated under sub. (3) during the previous year.
(d) Net certified accommodation credits are the sum of all volatile organic compound growth accommodation credits certified to date under s. 285.63 (7) or (8) minus the sum of the actual annual emissions of volatile organic compounds for the year 2 years before the specified year attributable to the sources receiving volatile organic compound growth accommodation credits certified to date under s. 285.63 (7) or (8).
(e) Net offset credits are the sum of all allowable emissions of volatile organic compounds authorized to date attributable to sources subject to an annual volatile organic compounds emission limitation that is specified in an air pollution control permit to operate under an emission reduction option or specified as an emission credit under a plan approved by the U.S. environmental protection agency under 42 USC 7502 (a) or in reports submitted to the U.S. environmental protection agency under the plan minus the sum of the actual annual emissions of volatile organic compounds for the year 2 years before the specified year attributable to sources subject to an annual volatile organic compounds emission limitation that is specified in an air pollution control permit to operate under an emission reduction option or specified as an emission credit under a plan approved by the U.S. environmental protection agency under 42 USC 7502 (a) or in reports submitted to the U.S. environmental protection agency under the plan.
(f) Set asides are:
1. Fifteen percent of the annual emissions of volatile organic compounds attributable to shutdowns of facilities in the volatile organic compound accommodation area since January 1, 1987; and
2. If a rule has been promulgated under sub. (3), 15 percent of the sum of the annual emissions reductions of volatile organic compounds attributable, since January 1, 1987, to the sources subject to the rule promulgated under sub. (3).
(2) Annual reports. The department shall prepare an annual report by January 15, which may be combined with other reports published by the department, that:
(a) States, on a calendar year basis, the total annual emissions, for the year 2 years before the year in which the report is prepared, of all volatile organic compounds in the volatile organic compound accommodation area, except methylene chloride and methyl chloroform and other volatile organic compounds that the department determines by rule to be compounds that do not contribute to the formation of ozone in the troposphere.
(b) Includes an annual plan for the management of the volatile organic compounds growth accommodation and replenishment and the growth accommodation replenishment grant program. At a minimum, the plan shall:
1. Indicate the amount of the growth accommodation at the beginning of the year.
2. Indicate the likely amount of the growth accommodation at the end of the year.
3. Report the status of the development and implementation of plans or rules under subs. (3) to (5).
4. Report if, during the prior year, the replenishment implementation period has expired.
(3) Growth accommodation replenishment. The department shall:
(a) Promulgate rules under s. 285.30 (6) (e), relating to the inspection of vehicles for tampering with air pollution control equipment.
(b) Promulgate rules restricting the amount of volatile organic compounds that may be contained in architectural coatings sold at retail in the volatile organic compound accommodation area or for use by a service provider in the volatile organic compound accommodation area. The department may exempt from a rule under this paragraph one or more categories of architectural coatings, based upon the type of coating or the use to which a coating is put, if it would be technically impractical to prohibit a category of architectural coating. The proposed rules shall include a provision to allow for the limited sale and use of the supplies of prohibited architectural coatings that retailers and suppliers in the volatile organic compound area already have in stock at the time of promulgation of the rules.
(c) Promulgate rules requiring persons who refinish auto bodies in the volatile organic compound accommodation area to use compounds, as solvents to clean painting and related equipment, that do not react to form ozone in the troposphere. The proposed rules shall allow the use of cleaning solvents containing volatile organic compounds that were purchased before the effective date of the proposed rules.
(4) Report on new replenishment mechanisms. After expiration of the replenishment implementation period, if the department reports under sub. (2) (b) 1. or determines at any other time that the growth accommodation is less than 3,500 tons, the department shall, with the advice of the department of safety and professional services, submit a report to the chief clerk of each house of the legislature for distribution to the appropriate standing committees of the legislature under s. 13.172 (3) on how to most effectively and equitably replenish the growth accommodation. The report shall review existing studies and data to evaluate the accuracy of this state's state implementation plan with respect to the effect of emissions from inside and outside the volatile organic compound accommodation area on the ambient air quality within the area.
(5) Contingent restrictions on existing sources. If at any time the department finds that the growth accommodation is less than 2,500 tons and determines that it is unlikely that the growth accommodation will exceed 2,500 tons in the report under sub. (2) (b) 1. for the following year because of the inadequacy of replenishment activities at the time or because of facility shutdowns, the department shall implement the rules that specify emission limitations for emissions of volatile organic compounds from stationary sources located in the volatile organic compound accommodation area that were required to report their emissions under s. 299.15 during calendar year 1987. The emission limitations shall be designed to ensure that the growth accommodation in the subsequent year is not less than 2,500 tons. The emission limitations may not be more restrictive than the lowest achievable emission rate. The department shall implement the emission limitations by source category. For the purpose of this section, the department shall determine a source category according to the type and level of emissions. The department may also use other characteristics which relate to air pollution to determine source categories. The department shall implement the emission limitations based upon ease of implementation, cost-effectiveness and the relative equity of imposing a limitation upon a source category, given any prior limitations of emissions imposed upon that source category. To the extent feasible, the emission limitations shall provide affected sources the opportunity to choose to be subject to either an annual emission limitation or a more restrictive applicable reasonably available control technology rule than was in effect in 1987.
