Section 61-9.503.E.46 - Frequency of monitoring
(a) Sewage sludge.
(1) The frequency of monitoring for beryllium shall be as required in subpart C of 40 CFR part 61, and for mercury as required in subpart E of 40 CFR part 61.
(2) The frequency of monitoring for arsenic, cadmium, chromium, lead, and nickel in sewage sludge fed to a sewage sludge incinerator shall be the frequency in Table 1 of section503.46. Facilities which generate less than 290 metric tons of sludge per year and dispose of the sludge once per year or less, may request a reduction in monitoring to a frequency of once per year. The Department will review these requests on a case-by-case basis.

TABLE 1 OF Section 503.46--FREQUENCY OF MONITORING--INCINERATION

Amount of sewage sludge* (metric tons per 365 day period)

Frequency

Greater than zero but less than 1,500.

Once per quarter (four times per year)

Equal to or greater than 1,500 but less than 15,000.

Once per 60 days (six times per year)

(b) Total hydrocarbons, oxygen concentration, information to determine moisture content, and combustion temperatures. The total hydrocarbons concentration and oxygen concentration in the exit gas from a sewage sludge incinerator stack, the information used to measure moisture content in the exit gas, and the combustion temperatures for the sewage sludge incinerator shall be monitored continuously.
(c) Air pollution control device operating parameters. The frequency of monitoring for the sewage sludge incinerator air pollution control device operating parameters shall be specified by the Department.--For sewage sludge incinerators subject to the requirements in subpart O of 40 CFR part 60, the frequency of monitoring for the appropriate air pollution control device operating parameters shall be the frequency of monitoring in subpart O of 40 CFR part 60. For all other sewage sludge incinerators, the appropriate air pollution control device operating parameters shall be monitored at least daily.
