Permitting and Emissions Regulations 21

The official listing of attainment status designations is in 40 CFR 81 Subpart
C-Section 107 Attainment Status Designations. This subpart of the federal regulations
lists attainment areas by state and air quality control region. These regulations can be
accessed through the online resources described above. The U.S. EPA also operates a
Web page called the Green Book that lists nonattainment areas for criteria pollutants
(http://www.epa.gov/oar/oaqps/greenbk). This Web site offers a variety of ways
(by state, county, or pollutant) to search area attainment designations.
2.2 Facility Classification

A facility’s classification is determined by three factors: common owner or operator,
adjacent facilities, and the same industrial classification. For a municipal facility, the
operation of a wastewater treatment plant may be under the direction of a public
works director who may also oversee other municipal facilities. A regional authority
may have responsibilities only for the wastewater treatment operations even if the
treatment facility serves people in multiple communities. An operator of a privately
operated plant would be responsible only for the operations at that plant. It is pos-
sible for the solids-handling facility to be privatized even if the rest of the WWTP was
run by a municipal or regional authority. In this case, the owner/operator of the
solids-processing facility would have responsibility only for emissions associated
with that process.
If a regional authority has responsibility for more than one WWTP and associated
solids processing, the treatment plants would be considered separate facilities as long
as they are not adjacent to one another. A public roadway passing between the two
facilities is not sufficient to treat the facilities as separate operations. For example, a
regional authority may have several regional WWTPs that are separated geographi-
cally. The operation of the WWTPs would be considered separate facilities. If, however,
the solids-processing facility for all the regional plants was located adjacent to one of
the WWTP, then that WWTP and the solids-processing facility would be considered
one facility, as they are under common ownership and are adjacent to one another.
The CAA Amendments of 1990 also group facilities by major industrial classifi-
cation. Sanitary Services are part of the U.S. Department of Labor Standard Industrial
Classification (SIC) Major Group 4900 (the DOL main page for accessing the SIC is
http://www.osha.gov/pls/imis/sic_manual.html). The subgroup (Industrial Group
4950) includes collection systems and refuse systems. Thus, a municipality or
regional authority that operates a wastewater treatment plant and a solid waste man-
agement facility on adjacent properties must consider both operations as part of the
same facility.
