FACT SHEET

National Emission Standards for Hazardous Air Pollutants: Publicly Owned Treatment Works

- Final Rule Corrections

TODAY'S ACTION...

! The Environmental Protection Agency (EPA) is correcting the October 1999 promulgated rule.
These corrections do not change the emission control requirements or the impact of the rule.

! The action corrects grammatical, typographic, formatting, and cross-reference errors.

SUMMARY OF THE CORRECTIONS TO THE EPA'S PUBLICLY OWNED

TREATMENT WORKS RULE

! The action corrects an error in §63.1589 (a) where we incorrectly cross-reference

performance standards (i.e., §63.1586 (b)) instead of the intended equipment standard
provisions (i.e., §63.1586 (a)).

! The amendments correct typographic and formatting errors.

BACKGROUND

! The EPA promulgated National Emission Standards for Hazardous Air Pollutants (NESHAP)
for Publicly Owned Treatment Works (POTW) on October 26, 1999 (see 64 FR 57572).

! Emissions of HAP from POTW facilities occur during the treatment of wastewater received
from residential and commercial sources and industrial sources.

! In developing these NESHAP, the EPA established two source "subcategories":

(1) the industrial POTW treatment plants subcategory, which comprises the wastewater
treatment portion of POTW used by industry to treat their specific industrial waste streams to
meet other regulations under the Clean Air Act (e.g., benzene waste operations NESHAP,
hazardous organic NESHAP); and (2) the non-industrial POTW treatment plants subcategory,
which comprises the wastewater treatment portion of all other POTW that are major sources.
