Proposed Part 257 Air Quality Standards and Classifications

Part 257, Subparts 257-2 through 257-10, list the New York State Air Quality Standards (SAQS) promulgated by the Department over several decades. A number of these SAQS are outdated and have been superseded by Federal air quality standards and are proposed to be repealed or revised.

The following subparts, which have been superseded by stricter Federal regulations, will be repealed:

257-3 – Air Quality Standards - Particulates

257-3.3 Standards for Suspended Particulates. The 24-hour suspended particulate (PM10 particles) standard is outdated and will be repealed.

The Federal annual PM10 standard was repealed in 2006 but NYS still lists an annual standard in Subpart 257-3 and will be repealed.

257-4 – Air Quality Standards – Carbon Monoxide

257-5 – Air Quality Standards – Photochemical Oxidants

257-6 – Air Quality Standards – Hydrocarbons (non-methane)

257-7 – Air Quality Standards – Nitrogen Dioxide (NO2)

257-9 – Air Quality Standards – Beryllium

The State Ambient Air Quality Standards for Fluorides and Hydrogen Sulfide, 212- 8 and 212-10 respectively, were revised to allow for improved monitoring methods.

Written comments on the proposed rule may be submitted until 5 p.m. on September 23, 2019.
