Section 1200-03-16-.15 - SEWAGE TREATMENT PLANT INCINERATORS(1) Applicability. The provisions of this rule shall apply to each incinerator commenced on or after April 21, 1976, which burns the sludge produced by municipal sewage treatment facilities.(2) Standards for particulate matter and opacity. On and after the date on which the performance test required to be conducted by paragraph .01(5) of this chapter is completed, no owner or operator of any sewage sludge incinerator subject to the provisions of this rule shall discharge or cause the discharge into the atmosphere of: (a) Particulate matter at a rate in excess of 0.65 g/kg dry sludge input (1.30 lb/ton dry sludge input).(b) Any gases which exhibit twenty (20) percent opacity or greater.(3) Monitoring of operations. The owner or operator of any sludge incinerator subject to the provisions of this rule shall: (a) Install, calibrate, maintain, and operate a flow measuring device which can be used to determine either the mass or volume of sludge charged to the incinerator. The flow measuring device shall have an accuracy of +5 percent over its operating range.(b) Provide access to the sludge charged so that a well-mixed representative grab sample of the sludge can be obtained.(4) Test methods and procedures:(a) For determining the concentration of particulate matter and associated moisture content, the sampling time for each run shall be at least sixty (60) minutes and the sampling rate shall be at least 0.015 dscm/min (0.53 dscf/min), except that shorter sampling times, when necessitated by process variables or other factors may be approved by the Technical Secretary.(b) Dry sludge charging rate shall be determined as follows: 1. Determine the mass (Sm) or volume (Sv) of sludge charged to the incinerator during each run using a flow measuring device meeting the requirements of subparagraph (3)(a) of this rule. If total input during a run is measured by a flow measuring device, such readings shall be used. Otherwise, record the flow measuring device readings at five (5) minute intervals during a run. Determine the quantity charged during each interval by averaging the flow rates at the beginning and end of the interval and then multiplying the average for each interval by the time for each interval. Then add the quantity for each interval to determine the total quantity charged during the entire run, (Sm) or (Sv).2. Collect samples of the sludge charged to the incinerator in non-porous collecting jars at the beginning of each run and at approximately one (1) hour intervals thereafter until the test ends, and determine for each sample the dry sludge content (total solids residue) in accordance with the method specified in "244 G. Method for Solid and Semisolid Samples," Standard Methods for the Examination of Water and Wastewater, Thirteenth Edition, American Public Health Association, Inc., New York, N.Y., 1971, pp. 539-41, except that: (i) Evaporating dishes shall be ignited to at least 103° C rather than the 550° C specified in step 3(a)(1).(ii) Determination of volatile residue, step 3(b) may be deleted.(iii) The quantity of dry sludge per unit sludge charged shall be determined in terms of either Rdv (metric units; mg dry sludge/liter sludge charged or English units: lb/ft3) or Rdm (metric units: mg dry sludge/mg sludge charged or English units: lb/lb).3. Determine the quantity of dry sludge per unit sludge charged in terms of either Rdv or Rdm. (i) If the volume of sludge charged is used: Sd = (60x10-3) RdvSv / T (Metric Units)
or
Sd = (8.021) RdvSv / T (English Units)
where:
Sd = average dry sludge charging rate during the run, kg/hr (English units: lb/hr).
Rdv = average quantity of dry sludge per unit volume of sludge charged to the incinerator, mg/l (English units: lb/ft3).
Sv = sludge charged to the incinerator during the run, m3 (English units: gal).
T = duration of run, min (English units: min).
60x10-3 = metric units conversion factor, 1-kg-min/m3-mg-hr.
8.021 = English units conversion factor, ft3-min/gal/hr.
(ii) If the mass of sludge charged is used: Sd = (60 Rdm Sm (Metric or English Units) / T
where:
Sd = average dry sludge charging rate during the run, kg/hr ( English units; lb/hr).
Rdm= average ratio of quantity of dry sludge to quantity of sludge charged to the incinerator, mg/mg (English units: lb/lb).
Sm = sludge charged during the run, kg (English units: lb).
T = duration of run, min (Metric or English units).
60 = conversion factor, min/hr (Metric or English units).
(c) Particulate emission rate shall be determined by: Caw = CsQs (Metric or English Units) where:
Caw = particulate matter mass emissions, mg/3hr (English units: lb/hr).
Cs = particulate matter concentration, mg/m3 (English units: lb/dscf).
Qs = volumetric stack gas flow rate, dscm/hr (English units; dscf/hr).
Qs and Cs shall be determined using Method 2 and 5, respectively.
(d) To check compliance, particulate emissions shall be determined as follows: Click to view Image
where:
Cds = particulate emission discharge, g/kg dry sludge (English units: lb/ton dry sludge).
10-3 = Metric conversion factor, g/mg.
2000 = English conversion factor, lb/ton.
