25 Pa. Code § 92a.12 - Treatment requirements
(a)
Specific treatment requirements and effluent limitations for each discharge
must be established based on the more stringent of the following:
(1) Requirements specified in Chapters 16,
77, 87-90, 93, 95, 96 and 102.
(2)
The applicable treatment requirements and effluent limitations to which a
discharge is subject under this chapter and the Federal Act .
(3) The treatment requirements and effluent
limitations of this title.
(b) When interstate or international agencies
under an interstate compact or international agreement establish applicable
effluent limitations or standards for dischargers of this Commonwealth to
surface waters that are more stringent than those required by this title, the
more stringent standards and limitations apply.
(c) If the Department has confirmed the
presence or critical habitat of endangered or threatened species under Federal
or State law or regulation, the Department will limit discharges to these
waters to ensure protection of these species and critical habitat.
(d) New or changed water quality standards or
treatment requirements may result from revisions to Chapters 16, 77, 87-90,
92a, 93, 95, 96 or 102, or other plans or determinations approved by the
Department . Upon notice from the Department , a permittee of an affected
facility shall promptly take the steps necessary to plan, obtain a permit or
other approval, and construct facilities or undertake other actions that are
necessary to comply with the new water quality standards or treatment
requirements.
(e) Within 180 days
of the receipt of the notice, the permittee shall submit to the Department
either a report establishing that its existing facilities are capable of
meeting the new water quality standards or treatment requirements, or a
schedule setting forth the nature and date of completion of steps that are
necessary to plan, obtain a permit or other approval, and construct facilities
or undertake other actions that are necessary to comply with the new water
quality standards or treatment requirements. The permittee shall comply with
the schedule approved by the Department .
(f) Whenever a point of projected withdrawal
for a new potable water supply not previously considered is identified by the
Department , the Department will notify a discharger if more stringent effluent
limitations are needed to protect the point of withdrawal. The discharger shall
meet the more stringent effluent limitations in accordance with a schedule
approved by the Department . The Department will issue orders directing
dischargers to achieve compliance or will impose permit modifications with
compliance schedules, when necessary.
