Section 336.1620. Emission of volatile organic compounds from existing flat wood paneling coating lines.

(1) A person shall not cause or allow the emission of volatile organic compounds from the coating of flat wood paneling from any existing coating line in excess of the applicable emission rates as follows:

(a)   Six pounds per 1,000 square feet of coated finished product from printed interior panels made of hardwood, plywood, or thin particle board, regardless of the number of coats applied.

(b)    Twelve pounds per 1,000 square feet of coated finished product from natural finish hardwood plywood panels, regardless of the number of coats applied.

(c)    Ten pounds per 1,000 square feet of coated finished product from class II finishes on hardboard panels, regardless of the number of coats applied.

(2)   A person who is responsible for the operation of a coating line that is subject to this rule shall obtain current information, and keep daily records necessary, for the determination of compliance with this rule, as required in R 336.2041.

(3)   For each coating line, compliance with the emission limits specified in this rule shall be based upon all of the following:

(a)   The volume-weighted average of all coatings which belong to the same coating category and which are used during each calendar day averaging period. The department may specifically authorize compliance to be based upon a longer averaging period, which shall not be more than 1 calendar month.

(b)   If coatings that belong to more than 1 coating category are used on the same coating line during the specified averaging period, then compliance shall be determined separately for each coating category.

(c)   The information and records as required by the provisions of subrule (2) of this rule.

(4)   Compliance with the limits specified in subrule (1) of this rule shall be determined using the method described in either R 336.2040(12)(i) if the coating line does not have an add-on emissions control device or R 336.2040(12)(j) if the coating line has 1 or more add-on emissions control devices.

(5)    This rule, with the exception of subrule (2) of this rule, does not apply to flat wood paneling coating lines which are within a stationary source and which have a combined actual emission rate of volatile organic compounds of less than 100 pounds per day or 2,000 pounds per month as of the effective date of this amendatory rule. If the combined actual emission rate equals or exceeds 100 pounds per day for a subsequent day or 2,000 pounds per month for a subsequent month, then this rule shall permanently apply to the coating lines.

(6)     A person may exclude low-use coatings that total 55 gallons or less per rolling 12-month period at a stationary source from the provisions of this rule, except for subrule (2) of this rule.

(7)   A person may discontinue the operation of a natural gas-fired afterburner, which is used to achieve compliance with the emission limits in this rule, between November 1 and March 31 unless the afterburner is used to achieve compliance with, or is required by, any of the following:

(a)   Any other provision of these rules.

(b)   A permit to install.

(c)   A permit to operate.

(d)  A voluntary agreement.

(e)   A performance contract.

(f)  A stipulation.

(g)   An order of the department.

(8)   If the operation of a natural gas-fired afterburner is discontinued between November 1 and March 31 under subrule (7) of this rule, then both of the following provisions shall apply between November 1 and March 31:

(a)   All other provisions of this rule, except the emission limits, shall remain in effect.

(b)   All other measures that are used to comply with the emission limits in this rule between April 1 and October 31 shall continue to be used.
