lbs./hr. shall be accomplished by the use of the equation: 

log E =1og 3 .59 + .62 log P 

P equal to or less than 30 tons/hr. and interpolation and extrapolation of the data for

Where: E _ "emission" in pounds per hour. 

P = Process weight rate in tons per hour. 
12 

(e)(3) For the purpose of this regulation, process weight per hour is the total weight of 

all materials introduced into any specific process that may cause any "emission" of "particulate 

matter." Solid fuels charged will be considered as part of the process weight, but liquid and 

gaseous fuels and combustion air will not. For a cyclical or batch operation, the process weight 

per hour will be derived by dividing the total process weight by the number of hours in one 

complete operation from the beginning of any given process to the completion thereof, excluding 

any time during which the equipment is idle . For a continuous operation, the process weight per 

hour will be derived by dividing the process weight for a typical period of time by the length of 

that period of time. 

(e)(4) Where the nature of any process or operation or the design of any equipment is 

such as to permit more than one interpretation of this regulation, the interpretation that results in 

the minimum value for "allowable emission" shall apply. 

(e)(5) For purposes of the regulation, the total process weight from all similar process 

units at a plant or "premises" shall be used for determining the maximum "allowable emission" 

or "particulate matter" that passes through a "stack" or "stacks." 

(e)(6) For the purposes of this regulation, when any material undergoes a series of 

operations which are capable of emitting "particulate matter" and which employ any combination 

of machines, equipment, or other devices used for processing the material either continuously or 

in batches, the total process weight for the series of operations shall be the weight of materials 

introduced to the series as a whole. Any material which is the product of any operation in the 

series shall not be counted as part of the process weight for any other operation in the series .]

Sec. 6. 

Section 22a-174-22 of the Regulations of Connecticut State Agencies is amended by revising 

subdivision (21) of subsection (a) as follows : 

(21) "Waste combustor" means an incinerator as defined in subsection [22a-174-18(c)] 22a-

.174-18 (a) of the Regulations of Connecticut State Agencies, a resources recovery facility as 

defined in section 22a-207 of the Connecticut General Statutes, or a sewage sludge incinerator. 

The term does not include a flare or an industrial fume incinerator. 

STATEMENT OF PURPOSE : 

Section 1 of this amendment revises R.C.S .A. section 22a-174-18 to : 1) specify the form and 

averaging time of the existing opacity standards for stationary sources; 2) add particulate matter 

standards appropriate to fuel-burning equipment using certain fossil fuels; 3) add particulate 

matter emissions standards and requirements for stationary reciprocating internal combustion 

engines; 4) add exemptions from the visible emissions standards for certain sources during 

certain periods of operation, including sources subject to federal New Source Performance 

Standards for opacity and smoke generating units used for training purposes by a branch of the 

U.S . military; 5) add an exemption from the section for municipal waste combustors to recognize 

of the promulgation of R.C.S .A. section 22a-174-38, which includes opacity and particulate 

matter standards for these sources; and 6) conform the overall format and language to current 

practices. 

Section 2 of this amendment adds a provision to subsection (c) of R.C.S .A. section 22a-174-38 

regarding the calculation of emission levels for reciprocating grate waste tire-fired incinerators . 

Section 3 of this amendment clarifies the use of emission reduction credits in the NOx trading 

program established by subsection (d) of R.C.S.A. section 22a-174-38 and changes the reporting 

date for submission of the annual NOx trading report. 

Section 4 of this amendment deletes opacity from the list of pollutants in R.C.S.A. section 22a- 174-38(k)(10) for which owners or operators must keep records of annual performance tests. In 

accordance with EPA guidelines for municipal waste combustors, only an initial performance 

test is required for opacity. Subsequent to the initial performance test, compliance with the 

opacity limit is measured using data from continuous emissions monitoring equipment. 

Sections 5 and 6 of this amendment correct internal citations within R.C.S.A. sections 22a-174- 19(f) and 22a-174-22(a)(21) consistent with the adoption of Section 1 of this amendment.
