This subpart applies to the exit gas from a sewage sludge incinerator stack.
The management practice in § 503.45(a), the frequency of monitoring requirement for total hydrocarbon concentration in § 503.46(b) and the recordkeeping requirements for total hydrocarbon concentration in § 503.47(c) and (n) do not apply if the following conditions are met:
The exit gas from a sewage sludge incinerator stack is monitored continuously for carbon monoxide.
The monthly average concentration of carbon monoxide in the exit gas from a sewage sludge incinerator stack, corrected for zero percent moisture and to seven percent oxygen, does not exceed 100 parts per million on a volumetric basis.
The person who fires sewage sludge in a sewage sludge incinerator retains the following information for five years:
The carbon monoxide concentrations in the exit gas; and
A calibration and maintenance log for the instrument used to measure the carbon monoxide concentration.
Class I sludge management facilities, POTWs (as defined in 40 CFR 501.2) with a design flow rate equal to or greater than one million gallons per day, and POTWs that serve a population of 10,000 people or greater submit the monthly average carbon monoxide concentrations in the exit gas to the permitting authority on February 19 of each year.
