You must demonstrate continuous compliance according to the requirements in paragraphs (a) through (c) of this section, unless you own or operate a very small municipal waste combustion unit or institutional waste incineration unit with a capacity less than or equal to 10 tons per day. If you own or operate a very small municipal waste combustion unit or institutional waste incineration unit with a capacity less than or equal to 10 tons per day, you must either comply with the requirements in paragraphs (a) and (c) of this section or the requirements in paragraph (d) of this section.

(a) You must conduct an annual performance test for all pollutants in table 2 or 2a to this subpart for each OSWI unit to determine compliance with the emission limitations, except if you own or operate an OSWI unit with a capacity greater than 10 tons per day you are not required to conduct an annual performance test for carbon monoxide. The annual performance test must be conducted using the test methods listed in table 2 or 2a to this subpart and the procedures in § 60.3027.

(b) You must continuously monitor carbon monoxide emissions to determine compliance with the carbon monoxide emissions limitation. Twelve-hour rolling average values, including CEMS data during startup and shutdown as defined in this subpart, are used to determine compliance. A 12-hour rolling average value above the carbon monoxide emission limit in table 2 or 2a to this subpart constitutes a deviation from the emission limitation.

(c) You must continuously monitor the operating parameters specified in § 60.3023(a) through (f) or established under § 60.3024. Three-hour rolling average values are used to determine compliance with the operating limits, except for bag leak detection system alarm time, unless a different averaging period is established under § 60.3024. A 3-hour rolling average value (unless a different averaging period is established under § 60.3024) above the established maximum or below the established minimum operating limits constitutes a deviation from the established operating limits. For bag leak detection systems, an alarm time of more than 5 percent of the operating time during a 6-month period constitutes a deviation from the operating limit. Operating limits do not apply during performance tests.

(d) For each very small municipal waste combustion unit or institutional waste incineration unit with capacity less than or equal to 10 tons per day, unless you comply with the requirements in paragraphs (a) and (c) of this section, you must comply with the requirements in paragraphs (d)(1) through (3) of this section.

(1) You must maintain the percentage of waste burned in each waste category within ±15 percent of the percentage of total waste burned on a mass basis as established for that waste category according to the waste profile established under § 60.3023(g). You must demonstrate that the percentage of waste burned in each waste category is maintained within ±15 percent of the percentage of total waste burned on a mass basis as established for that waste category according to the waste profile established under § 60.3023(g) according to paragraphs (d)(1)(i) through (iii) of this section.

(i) At the end of each calendar quarter, you must determine the mass of waste burned in each waste category for that quarter. You must determine the total waste burned during the quarter by summing the quarterly totals for all the waste categories. You must then determine the amount of waste burned in each waste category as a percentage of the total waste burned on a mass basis by dividing the quarterly total in each waste category by the quarterly total waste burned.

(ii) You must also maintain records as required in § 60.3046(p).

(iii) The values calculated in (d)(1)(i) must be ±15 percent of the percentage of total waste burned on a mass basis as established for that waste category according to the waste profile established under § 60.3023(g). Failure to maintain the percentage of waste burned in each waste category within ±15 percent of the percentage established for that waste category in any calendar quarter constitutes a deviation.

(2) If you want to establish new operating parameter limits or establish a different waste profile, you must comply with § 60.3036(b).

(3) You must continuously monitor the operating parameters specified in § 60.3023(b) through (f), as applicable. The total daily charge rate is used to determine compliance with the charge rate limit in § 60.3023(a). For the operating parameters in § 60.3023(b) through (f), determine compliance as described in paragraph (d)(3)(i) or (ii) of this section. Failure to meet the operating parameters specified in § 60.3023(a) through (f) is a deviation.

(i) Three-hour rolling average values are used to determine compliance with the operating parameter limits, unless your unit operates on a batch basis and it is operated for less than three hours.

(ii) If your unit operates on a batch basis, and you operate for less than three hours, compliance with the operating parameter limits is determined by averaging the operating parameter over the length of the batch operation.
