SEC. 5A-7. CITY AIR POLLUTION STANDARDS.

(a) No person may cause, suffer, allow, or permit the emission of lead or its compounds (measured as elemental lead) so as to cause or contribute to an exceedence of the ambient air quality standard for lead. The ambient air quality standard for lead and its compounds, measured as elemental lead by a reference method based on appendix G of 40 CFR 50, or by an equivalent method, is 1.5 micrograms per cubic meter, maximum arithmetic mean averaged over 30 calendar days. The data used to obtain the arithmetic mean averaged over 30 calendar days shall consist of individual 24-hour concentrations obtained on a regular sampling schedule and shall contain a minimum of 15 validated samples.

(b) No person or persons may cause, suffer, allow, or permit emissions of lead from any source or sources on a property or from multiple sources operated on contiguous properties to exceed any of the following net ground level concentrations:

(1) 8.3 micrograms of lead per cubic meter of air averaged over one hour; or

(2) 6.5 micrograms of lead per cubic meter of air averaged over three hours; or

(3) 5.2 micrograms of lead per cubic meter of air averaged over five hours.

(c) Odors (emission standard). A stationary source may not emit beyond its property line an odor, the strength of which equals or exceeds two odor units, as measured by the director on a Barnaby-Cheney Scentometer or equivalent odor-testing device.

(d) The director shall prescribe by rule such additional regulations as he determines are necessary to implement this section and may provide by rule for temporary suspension of the application of the air pollution standards prescribed by this section to a source that is operating under unusual conditions or circumstances that prevent compliance.
