Current through Register Vol. 56, No. 11, June 3, 2024

Section 7:27-27.4 - Municipal solid waste (MSW) incinerators

(a) Each owner or operator of an MSW incinerator of any size shall operate the MSW incinerator in accordance with provisions specified in either (a)1 or 2 below. Compliance with this standard shall be measured pursuant to (b) below.

1. The emissions of mercury from any MSW incinerator shall not exceed 28.0 [mu] g/dscm, corrected to seven percent oxygen, based on the annual average of all valid stack emission tests performed for four consecutive quarters; or

2. The reduction efficiency for control of mercury emissions of the air pollution control apparatus of any MSW incinerator shall be at least:

i. 80 percent until January 3, 2006 determined quarterly based on all valid stack emission testing performed during each quarter;

ii. 85 percent on and after January 3, 2006 based on the annual average of all valid tests performed for each four consecutive quarters; and

iii. 95 percent on and after January 3, 2012 based on the annual average of all valid tests performed for each four consecutive quarters.

(b) The owner or operator of a MSW incinerator that is demonstrating compliance with the mercury emission standard of (a)1 above shall conduct stack emission testing every quarter to measure mercury in the gas stream at the exit of the control apparatus. The owner or operator of a MSW incinerator that is demonstrating compliance with the control efficiency standards of (a)2i, ii or iii above shall conduct stack emission testing every quarter to measure mercury in the gas stream at the inlet of the air pollution control apparatus serving each incinerator and simultaneously conduct stack emission testing every quarter to measure mercury in the gas stream at the exit of the control apparatus. There shall be at least three valid tests per quarter and at least 45 days between the stack emission testing performed for a given quarter and the stack emission testing performed for the preceding quarter, unless a shorter period is approved by the Department. The stack emission testing shall be conducted in accordance with a stack emission test protocol approved pursuant to 7:27-27.8(a) and (b).

(c) Notwithstanding the provisions of (b) above, any owner or operator who achieves and maintains compliance with (a) above, for all applicable incinerators located at a facility, during eight consecutive quarters, may reduce the frequency of stack emission testing from each quarter to stack emission testing performed every fourth quarter after the eighth quarter test in which annual average compliance was determined. However, if subsequent stack emission testing fails to demonstrate compliance with (a) above, then the frequency of stack emission testing shall revert to that indicated in (b) above for the unit that failed.

(d) An MSW incinerator that complies with the requirements of this subsection is not subject to the requirements of (a)2iii above.

1. Beginning on April 1, 2006, the average emissions of mercury from the entire MSW incinerator facility calculated under (d)3 below shall not exceed 14.0 [mu] g/dscm, corrected to seven percent oxygen.

2. In each quarter, three valid stack emission tests shall be conducted for each unit at the MSW incinerator facility.

3. The average emissions of mercury from the entire MSW incinerator facility shall be calculated for each period of 12 consecutive quarters. The average emissions shall be equal to the sum of the mercury emissions in all valid stack emission tests for all units, divided by the number of stack emission tests conducted during the 12 quarter period.

4. If the facility fails to demonstrate mercury emissions less than the 14.0 [mu] g/dscm (corrected to seven percent oxygen) average for any 12 consecutive quarter period up until January 3, 2012, the requirements of (a)2iii above shall apply starting January 3, 2012.

5. If the facility demonstrates mercury emissions less than the 14.0 [mu] g/dscm (corrected to seven percent oxygen) average for all rolling 12 consecutive quarter periods up until January 3, 2012 and the facility chooses to continue to comply with this standard after this trial period, the 14.0 [mu] g/dscm limit (corrected to seven percent oxygen) shall apply for every 12 consecutive quarter periods thereafter. Compliance shall be determined using valid stack emission test data from the first quarter after the end of the trial period and using the valid stack emission test data from the 11 quarters immediately preceding the first quarter. Thereafter, the facility shall not revert back to compliance with (a)2iii above.
