Local limits are wastewater limitations that apply to commercial
and industrial facilities that discharge to a publicly
owned treatment works
(POTW). Local limits are developed to meet the pretreatment program
objectives and site-specific needs of the local POTW and the
receiving stream.
Local limits control the pollutants in the wastewater discharges
from commercial and industrial facilities and apply at the
"end-of-pipe" from the facility. The regulations under 40 CFR
§403.5(d) give
the POTW the authority to enforce its local limits.
Who Needs to Develop Local Limits?
The following POTWs are required by 40 CFR
§403.5(c) to
develop local limits:
-
POTWs required to implement an approved pretreatment program
need to develop local limits, or demonstrate that they are not
necessary
-
other POTWs where wastewater discharges from commercial and
industrial facilities have caused interference or
pass
through, and
such violation is likely to recur
This requirement is contained in the POTW’s Texas
Pollutant Discharge Elimination System (TPDES) permit.
