Sec. 503.45  Management practices.

    (a)(1) An instrument that continuously measures and records the 
total hydrocarbons concentration in the sewage sludge incinerator stack 
exit gas shall be installed, calibrated, operated, and maintained for a 
sewage sludge incinerator.
    (2) The total hydrocarbons instrument shall employ a flame 
ionization detector; shall have a heated sampling line maintained at a 
temperature of 150 degrees Celsius or higher at all times; and shall be 
calibrated at least once every 24-hour operating period using propane.
    (b) An instrument that continuously measures and records the oxygen 
concentration in the sewage sludge incinerator stack exit gas shall be 
installed, calibrated, operated, and maintained for a sewage sludge 
incinerator.
    (c) An instrument that continuously measures and records information 
used to determine the moisture content in the sewage sludge incinerator 
stack exit gas shall be installed, calibrated, operated, and maintained 
for a sewage sludge incinerator.
    (d) An instrument that continuously measures and records combustion 
temperatures shall be installed, calibrated, operated, and maintained 
for a sewage sludge incinerator.
    (e) Operation of a sewage sludge incinerator shall not cause the 
operating combustion temperature for the sewage sludge incinerator to 
exceed the performance test combustion temperature by more than 20 
percent.
    (f) An air pollution control device shall be appropriate for the 
type of sewage sludge incinerator and the operating parameters for the 
air pollution control device shall be adequate to indicate proper 
performance of the air pollution control device. For sewage sludge 
incinerators subject to the requirements in subpart O of 40 CFR part 60, 
operation of the air pollution control device shall not violate the 
requirements for the air pollution control device in subpart O of 40 CFR 
part 60. For all other sewage sludge incinerators, operation of the air 
pollution control device shall not cause a significant exceedance of the 
average value

for the air pollution control device operating parameters from the 
performance test required by Sec. 503.43 (c)(3) and (d)(5).
    (g) Sewage sludge shall not be fired in a sewage sludge incinerator 
if it is likely to adversely affect a threatened or endangered species 
listed under section 4 of the Endangered Species Act or its designated 
critical habitat.
    (h) The instruments required in Sec. 503.45(a)-(d) shall be 
appropriate for the type of sewage sludge incinerator.
