(a) Users
shall provide wastewater treatment as necessary to comply with this
division and shall achieve compliance with all categorical pretreatment
standards, local limits, authority local limits and/or pretreatment
requirements including other measures implemented by Gulf Coast Waste
Disposal Authority, and prohibitions set forth in this division within
the timeframe specified by EPA, the state, or the director, whichever
is more stringent.
(b) Pretreatment
facilities necessary for compliance must be provided, operated, inspected,
and maintained at the user’s expense.
(c) Detailed
plans describing pretreatment facilities and their operating procedures
shall be submitted to the director for review and shall be acceptable
by the director prior to construction of the facilities. The review
of such plans and/or operating procedures shall in no way relieve
the user from the responsibility of modifying such facilities as necessary
to produce a discharge acceptable to the control authority under the
conditions of this division.
(d) Subsequent
significant changes in the pretreatment facilities or methods of operation
must be reported to and be acceptable to the control authority prior
to the initiation of the changes.
(e) The
director may require users, at the user’s expense, to restrict
their discharge during peak flow periods, discharge certain wastewater
only into specifically designated sewers, relocate and/or consolidate
points of discharge, separate sewage wastestreams from process wastestreams,
and initiate such other conditions as may be necessary to protect
the POTW(s) and determine the user’s compliance with the requirements
and objectives of this division.
(f) The
director may require any user discharging to the POTW(s) to install
and maintain, on their property and at their expense, a suitable storage
and flow control facility to ensure equalization of flow or compliance
prior to discharge.
(g) Grease,
oil, and sand interceptors shall be provided by the user when, in
the opinion of the director, they are necessary for the proper handling
of wastewater containing excessive amounts of grease, oil, or sand,
except that such interceptors shall not be required for property solely
used for residential purposes. All interceptors shall be of type and
capacity approved by the city’s building and inspection department
and shall be so located so as to be easily accessible for cleaning
and inspection.
(h) Such
interceptors shall be inspected, cleaned, and repaired regularly,
as needed, by the user at the user’s expense.
(i) Users
with the potential to discharge flammable substances may be required
to install and maintain an approved combustible meter.
(Ordinance 2011-01, sec. 1, adopted 1/11/11)
(a) At
least once every two (2) years, the director shall evaluate whether
each significant industrial user needs an accidental discharge/slug
control plan.
(b) Within
one (1) year of being designated as a significant industrial user,
the director will determine whether the new significant industrial
user needs a plan or other action to control slug discharges.
(c) When
conditions may exist that reasonably could result in an accidental
or slug discharge, the director may require any user to develop, submit
for approval, and implement an accidental discharge/slug plan or take
other such actions that may be required to control slug discharges.
These requirements may be incorporated into the user’s permit.
Review and approval of the plan shall not relieve the user from any
responsibility associated with an accidental/slug discharge.
(d) The
accidental discharge/slug control plan shall address, at a minimum,
the following:
(1) Description of discharge practices, including non-routine batch discharges;
(2) Description of stored chemicals;
(3) Procedures for immediately notifying the director of any accidental or slug discharges, as required by section
13-2-265 of this division.
(4) Procedures to prevent adverse impact from any accidental or slug
discharge, including, but not limited to, inspection and maintenance
of storage areas, handling and transfer of materials, loading and
unloading operations, control of plant site runoff, worker training,
monitoring, building of containment structures or equipment, measures
for containing toxic organic pollutants, including solvents, and plans
and equipment for emergency response.
(e) Each
user, deemed necessary by the director, shall provide and maintain
at the user’s expense such facilities determined to be necessary
to provide protection from accidental or slug discharges. Design specifications
for these facilities must be submitted to the director for review
and approval. Review and approval of such specifications shall not
relieve the user from the responsibility of modifying the facility
to meet the requirements of this division.
(f) When
deemed necessary by the director because of a reasonable risk of an
accidental or slug discharge, a notice shall be permanently posted
in conspicuous places on the user’s premises advising employees
who to call in the event of a slug or accidental discharge. Employers
shall instruct all employees who may cause or discover a discharge
concerning emergency notification procedures.
