Code of Colorado Regulations · Regulation Number 1

EMISSION CONTROL FOR PARTICULATE MATTER, SMOKE, CARBON MONOXIDE, AND SULFUR OXIDES 5 CCR 1001-3

This regulation addresses emission control for particulate matter, smoke, carbon monoxide, and sulfur oxides. The detail is in the listed sections, which cover applicability and general provisions, smoke and opacity requirements, particulate-matter requirements, continuous emission monitoring, iron and steel plant operations, sulfur dioxide emission regulations, and restrictions on the use of oil as a backup fuel. The regulation also includes appendices on a method for measuring opacity from fugitive particulate emission sources and a method of measuring off-property transport of fugitive particulate emissions.

I.A.1.

Regulation Number 1 applies to all sources in Colorado—both new and existing—whether or not they have a permit. Unless a specific provision says it applies only to attainment, attainment/maintenance, or nonattainment areas, the rule applies statewide (unclassifiable areas count as attainment). If this regulation conflicts with another regulation of the commission, the stricter limit applies, except that a specific limit for a particular source takes precedence over a general limit that is inconsistent.

I.B.5.

Plain-language summary:

Haul roads are roads used by commercial, industrial, or government operations to haul materials, where the general public does not have a right to use them.

I.B.6.

Intermittent Sources are stationary air pollution sources that don't run continuously long enough to allow opacity readings using EPA Method 9. This is a definition only; it does not impose any requirements.

I.B.9.

"Welfare" in this regulation means effects on public welfare, which include (but are not limited to) impacts on soils, water, crops, vegetation, man-made materials, animals, wildlife, weather, visibility, climate, property damage and deterioration, transportation hazards, economic values, and personal comfort and well-being.
