(2)Each municipal waste combustor shall meet the following operational standards:
(A)The concentration of carbon monoxide at the municipal waste combustor outlet shall not exceed the concentration in:
(i)table 3 of 40 CFR 60.34b(a) for large municipal waste combustors. The municipal waste combustor technology named in this table is defined in 40 CFR 60.51b; and
(ii)table 5 of 40 CFR 60 Subpart BBBB. The municipal waste combustor technology named in this table is defined in 40 CFR 60.1940.
(B)The load level shall not exceed 110 percent of the maximum demonstrated municipal waste combustor unit load (four-hour block average).
(C)The temperature at which the combustor operates measured at the particulate matter control device inlet shall not exceed 63 degrees F above the maximum demonstrated particulate matter control device temperature (four-hour block average).
(D)The owner or operator of a municipal waste combustor with activated carbon control system to control dioxins and furans or mercury emissions shall maintain an eight-hour block average carbon feed rate at or above the highest average level established during the most recent dioxins and furans or mercury test and shall evaluate total carbon usage for each calendar quarter. The total amount of carbon purchased and delivered to the municipal waste combustor shall be at or above the required quarterly usage of carbon and shall be calculated as specified in equation four or five in 40 CFR 60.1935(f).
(E)The owner or operator of a municipal waste combustor shall be exempted from limits on load level,
temperature at the inlet of the particular matter control device, and carbon feed rate during:
(i)the annual tests for dioxins and furans;
(ii)the annual mercury tests for carbon feed requirements only;
(iii)the two weeks preceding the annual tests for dioxins and furans;
(iv)the two weeks preceding the annual mercury tests (for carbon feed rate requirements only); and
(v)any activities to improve the performance of the municipal waste combustor or its emission control including performance evaluations and diagnostic or new technology testing.
(3)Except during start-up where the procedure has been approved according to Rule .0535(g) of this Subchapter, waste material shall not be loaded into any incinerator subject to this Rule when the temperature is below the minimum required temperature. Start-up procedures may be determined on a case-by-case basis according to Rule .0535(g) of this Subchapter and Subparagraph (4) of this Paragraph. Incinerators subject to this Rule shall have automatic auxiliary burners that are capable of maintaining the required minimum temperature in the secondary chamber excluding the heat content of the wastes.
(4)The operational standards of this Paragraph apply at all times except during periods of municipal waste combustor startup, shutdown, or malfunction that last no more than:
(A) three hours for Class I combustors; or
(B)three hours except as specified in 60.58b(a)(1)(iii) for large municipal waste combustors.
