Current through Vol. 24-21, December 1, 2024

Section R. 336.1101 - Definitions; A

Rule 101. As used in these rules:

(a) "Act" means 1994 PA 451, MCL 324.5501 to 324.5542.

(b) "Actual emissions" means the average rate, in tons per year, at which the process or process equipment actually emitted the air contaminant during the preceding 2-year period and which was representative of the normal operation of the process or process equipment. A different time period may be used if the time period can be demonstrated to be more representative of normal operation. Actual emissions shall be calculated using the process's or process equipment's actual operating hours, production rates, and types of materials processed, stored, or combusted during the selected time period. The department may presume that the actual emissions for a process or process equipment shall equal the allowable emissions for such process or process equipment if the allowable emissions are identified in the demonstration for an approved state implementation plan. For any process or process equipment that has not begun normal operations, actual emissions shall equal the allowable emissions. The term "actual emissions" is not applicable in parts 6 and 7 of these rules.

(c) "Adhesion prime" means a coating that is applied to a polyolefin part to promote the adhesion of a subsequent coating. An adhesion prime is clearly identified as an adhesion prime or adhesion promoter on its accompanying material safety data sheet.

(d) "Affected states" means all states that are contiguous to the state of Michigan and whose air quality may be affected by a proposed operating permit, operating permit modification, or operating permit renewal or that are within 50 miles of the stationary source for which a permit action is proposed.

(e) "Air-cleaning device" means air pollution control equipment.

(f) "Air contaminant" means a dust, fume, gas, mist, odor, smoke, vapor, or any combination thereof.

(g) "Air-dried coating" means a coating that is dried by the use of air or forced warm air at temperatures up to 90 degrees Celsius (194 degrees Fahrenheit).

(h) "Air pollution" has the same meaning as defined in section 5501 of the act.

(i) "Air pollution control equipment" means any method, process, or equipment that removes, reduces, or renders less noxious air contaminants discharged into the atmosphere.

(j) "Air quality standard" means the concentration and duration of an air contaminant specified by the department or by the national ambient air quality standards as contained in the provisions of 40 C.F.R. part 50, adopted by reference in R 336.1902, whichever is more restrictive, as the maximum acceptable concentration and duration of that contaminant in the ambient air.

(k) "Allowable emissions" means the emission rate calculated using the maximum rated capacity of the process or process equipment, unless there are legally enforceable limits that restrict the operating rate or the hours of operation, or both, and the most stringent of the following:

(i) Any applicable standards pursuant to the clean air act.

(ii) Any applicable emission limit specified in these rules, including a limit that has a future compliance date.

(iii) Any applicable emission rate specified as a legally enforceable permit condition or voluntary agreement, performance contract, stipulation, or order of the department, including a rate that has a future compliance date.

(l) "Alternate opacity" means that standard for density of emission which is greater than the standard specified in R 336.1301(1) and which is established by the department for a specific process or process equipment in accordance with the provisions of R 336.1301(4).

(m) "Alternative method," with respect to source sampling, means a method or set of procedures for obtaining source samples which is not a reference test method or an equivalent method and which has been demonstrated, to the department's satisfaction, to, in specific cases, produce results adequate for a performance test.

(n) "Ambient air" means that part of the atmosphere outside of buildings to which the general public has access.

(o) "Applicable requirement" means any of the following as they apply to process or process equipment, including requirements that have been approved as administrative rules under the act pursuant to the administrative procedures act, 1969 PA 306, MCL 24.201 to 24.328 or promulgated by the United States environmental protection agency through final rulemaking at the time of issuance of a permit under the act and which will become effective during the permit term:

(i) A standard or other requirement provided for in the Michigan state implementation plan, as approved or promulgated by the United States environmental protection agency through rulemaking under title I of the clean air act, that implements the relevant requirements of the clean air act, including any revisions to that plan promulgated in 40 C.F.R. part 52.

(ii) A standard or requirement enacted as a part of the act or promulgated in administrative rules pursuant to the act.

(iii) A term or condition of any permit issued pursuant to the act or regulations approved or promulgated through rulemaking under title I of the clean air act, including parts C or D.

(iv) A term or condition of an order entered pursuant to the act that is necessary to ensure or demonstrate compliance with any other applicable requirement.

(v) A term or condition of a permit issued by the United States environmental protection agency pursuant to title I, subpart C, of the clean air act.

(vi) A term or condition of any permit issued pursuant to the Wayne county air pollution control ordinance, adopted pursuant to the home rule charter for Wayne county, resolution no. 85-305, as amended by resolution no. 89-213.

(vii) A term or condition of an order entered pursuant to the Wayne county air pollution control ordinance, adopted pursuant to the home rule charter for Wayne county, resolution no. 85-305, as amended by resolution no. 89-213, that is necessary to ensure or demonstrate compliance with any other applicable requirement.

(viii) A standard or other requirement under the clean air act, including any of the following:

(A) A standard for the performance of new stationary sources or other requirement under section 111 of the clean air act, including section 111(d).

(B) A standard for hazardous air pollutants or other requirement under section 112 of the clean air act, including any requirement concerning accident prevention under section 112(r)(7).

(C) A standard or other requirement of the acid rain program under title IV of the clean air act or the regulations promulgated thereunder.

(D) A requirement for enhanced monitoring established pursuant to section 114(a)(3) or 504(b) of the clean air act.

(E) A standard or other requirement governing solid waste incineration under section 129 of the clean air act.

(F) A standard or other requirement for consumer and commercial products under section 183(e) of the clean air act.

(G) A standard or other requirement for tank vessels under section 183(f) of the clean air act.

(H) A standard or other requirement of the regulations promulgated to protect stratospheric ozone under title VI of the clean air act, unless the administrator of the United States environmental protection agency has determined that the standard or requirement need not be contained in a renewable operating permit required under title V of the clean air act.

(I) A national ambient air quality standard or increment or visibility requirement under the clean air act, title I, part C, but only as it would apply to temporary sources. Any applicable requirement which results solely from the requirements of the act, the rules promulgated under the act, or the home rule charter for Wayne county, resolution no. 85-305, as amended by resolution no. 89-213, is not enforceable under the clean air act.

(p) "Applicant" means a person who owns or operates a stationary source and who files an application for a permit with the department.
