§584-A. -- enactment
The ambient air quality standards set forth in this section, which are expressed in terms of 25` centigrade and 760 millimeters of mercury pressure, shall apply in all air quality regions: [1971, c. 570, (NEW).]
1. Particulate matter. For purposes of statutory interpretation, rules, licensing determinations, policy guidance and all other actions by the department or the board relating to the control of particulate matter, any reference to an ambient air quality standard is interpreted to refer to the national ambient air quality standard for particulate matter established pursuant to Section 109 of the federal Clean Air Act as amended, 42 United States Code, Section 7409.
A.
[2009, c. 121, §15 (RP).]
B.
[2009, c. 121, §15 (RP).]
[ 2009, c. 121, §15 (RPR) .]
2. Sulfur dioxide.
A. Sulfur dioxide concentration for any 3-hour period at any location shall not exceed 1150 micrograms per cubic meter, except once per year. [1987, c. 242, (AMD).]
B. Sulfur dioxide concentration for any 24-hour period at any location shall not exceed 230 micrograms per cubic meter, except once per year. [1987, c. 242, (AMD).]
C. The annual arithmetic mean of the 24-hour average sulfur dioxide concentrations at any location shall not exceed 57 micrograms per cubic meter. [1971, c. 570, (NEW).]
[ 1987, c. 242, (AMD) .]
3. Carbon monoxide.
A. Carbon monoxide concentration for any 8-hour period at any location shall not exceed 10 milligrams per cubic meter, except once per year. [1971, c. 570, (NEW).]
B. Carbon monoxide concentration for any 1-hour period at any location shall not exceed 40 milligrams per cubic meter, except once per year. [1971, c. 570, (NEW).]
[ 1971, c. 570, (NEW) .]
4. Photochemical oxidant.
[ 1995, c. 306, §1 (RP) .]
4-A. Ozone. For purposes of statutory interpretation, rules, regulations, licensing determinations, policy guidance and all other actions by the department or the board relating to the control of ozone precursors for the purpose of controlling ozone or photochemical oxidant, any reference to an ambient air quality standard is interpreted to refer to the national ambient air quality standard for ozone established pursuant to Section 109 of the federal Clean Air Act as amended, 42 United States Code, Section 7409.
[ 1995, c. 306, §2 (NEW) .]
5. Hydrocarbon.
[ 1995, c. 642, §7 (RP) .]
6. Nitrogen dioxide. The annual arithmetic mean of the 24-hour average nitrogen dioxide concentration at any location shall not exceed 100 micrograms per cubic meter.
[ 1971, c. 570, (NEW) .]
7. Lead. The maximum 24-hour lead concentration at any location shall be 1.5 micrograms per cubic meter, which standard may be exceeded once per year.
[ 1981, c. 157, (NEW) .]
8. Chromium.
A. Until the time that an analytical procedure for measuring hexavalent chromium in the ambient air is approved:
(1) The maximum 24-hour total chromium concentration at any location shall not exceed 0.3 micrograms per cubic meter; and
(2) The annual geometric mean of the total chromium concentrations at any location shall not exceed 0.05 micrograms per cubic meter. [1983, c. 359, §1 (NEW).]
B. Subsequent to the establishment of an acceptable analytical procedure for measuring hexavalent chromium in the ambient air:
(1) The maximum 24-hour ambient air quality impact of hexavalent chromium from a potential source of hexavalent chromium air emissions, as defined in section 611, subsection 2, shall not exceed the minimum detection limit of that procedure, or 1.0 nanogram per cubic meter, whichever is greater. [1983, c. 359, §1 (NEW).]
[ 1983, c. 359, §1 (NEW) .]
9. Perchloroethylene. The maximum annual concentration of perchloroethylene at any location may not exceed 0.01 micrograms per cubic meter.
[ 1991, c. 646, (NEW) .]
10. Toluene. The ambient air quality standards for toluene are as follows.
A. The maximum concentration of toluene at any location may not exceed 15,000 micrograms per cubic meter. [1991, c. 646, (NEW).]
B. The maximum concentration of toluene for any 24-hour period at any location may not exceed 260 micrograms per cubic meter. [1991, c. 646, (NEW).]
C. The maximum annual concentration of toluene at any location may not exceed 180 micrograms per cubic meter. [1991, c. 646, (NEW).]
