accordance with 30 TEXAS ADMINISTRATIVE CODE §312.143.
3-1
3.3 CLEANING SCHEDULES
• Grease traps/interceptors shall be cleaned as often as necessary to ensure that sediment and
floating materials do not accumulate to impair the efficiency of the grease trap/interceptor;
to ensure the discharge is in compliance with local discharge limits; and to ensure no visible
grease is observed in discharge.
• The POTW has the ability to inspect and evaluate grease traps and grease interceptors at any
time.
• Grease traps/interceptors subject to these standards shall be completely evacuated a
minimum of every ninety (90) days, or more frequently when:
o twenty-five (25) percent or more of the wetted height of the grease
trap/interceptor, as measured from the bottom of the device to the invert of the
outlet pipe, contains floating materials, sediment, oils or greases; or
o the discharge exceeds BOD, COD, TSS, FOG, pH, or other pollutant levels
established by the POTW; or
o if there is a history of non-compliance.
• Any person who owns or operates a grease trap/interceptor may submit to the POTW a
request in writing for an exception to the ninety (90) day pumping frequency of their grease
trap/interceptor. The POTW may grant an extension for required cleaning frequency on a
case -by -case basis when:
o the grease trap/interceptor owner/operator has demonstrated the specific
trap/interceptor will produce an effluent, based on defensible analytical results,
in consistent compliance with established local discharge limits such as BOD,
TSS, FOG, or other parameters as determined by the POTW, or
o less than twenty-five (25) percent of the wetted height of the grease
trap/interceptor, as measured from the bottom of the device to the invert of the
outlet pipe, contains floating materials, sediment, oils or greases.

3.4 MANIFEST REQUIREMENTS
• Each pump -out of a grease trap/interceptor must be accompanied by a manifest to be used
for record keeping purposes.
• Persons who generate, collect and transport grease waste shall maintain a record of each
individual collection and deposit. Such records shall be in the form of a manifest. The manifest
shall include:
o name, address, telephone, and commission registration number of transporter;
o name, signature, address, and phone number of the person who generated the
waste and the date collected;
o type and amount(s) of waste collected or transported;
o name and signature(s) of responsible person(s) collecting, transporting, and
depositing the waste;
o date and place where the waste was deposited;
o identification (permit or site registration number, location, and operator) of the
facility where the waste was deposited;
o name and signature of facility on -site representative acknowledging receipt of
the waste and the amount of waste received;
o the volume of the grease waste received; and
o a consecutive numerical tracking number to assist transporters, waste
generators, and regulating authorities in tracking the volume of grease
transported.
■ Manifests shall be divided into five parts and records shall be maintained as follows.
o One part of the manifest shall have the generator and transporter information
completed and be given to the generator at the time of waste pickup.
o The remaining four parts of the manifest shall have all required information
completely filled out and signed by the appropriate party before distribution of
the manifest.
o One part of the manifest shall go to the receiving facility.
3-3
o One part shall go to the transporter, who shall retain a copy of all manifests
showing the collection and disposition of waste.
o One copy of the manifest shall be returned by the transporter to the person
who generated the wastes within 15 days after the waste is received at the
disposal or processing facility.
o One part of the manifest shall go to the local authority.
■ Copies of manifests returned to the waste generator shall be retained for five years and be
readily available for review by the POTW.
3.5 ALTERNATIVE TREATMENT
■ A person commits an offense if the person introduces, or causes, permits, or suffers the
introduction of any surfactant, solvent or emulsifier into a grease trap. Surfactants, solvents,
and emulsifiers are materials which allow the grease to pass from the trap into the collection
system, and include but are not limited to enzymes, soap, diesel, kerosene, terpene, and other
solvents.
■ It is an affirmative defense to an enforcement of Section 3.6.1 that the use of surfactants or
soaps is incidental to normal kitchen hygiene operations.
■ Bioremediation media may be used with the POTW's approval if the person has proved to the
satisfaction of the POTW that laboratory testing which is appropriate for the type of grease
trap to be used has verified that:
o The media is a pure live bacterial product which is not inactivated by the use of
domestic or commercial disinfectants and detergents, strong alkalis, acids,
and/or water temperatures of 160F (71C).
o The use of the media does not reduce the buoyancy of the grease layer in the
grease trap and does not increase the potential for oil and grease to be
discharged to the sanitary sewer.
o The use of the bioremediation media does not cause foaming in the sanitary
sewer.
o The BOD, COD, and TSS discharged to the sanitary sewer after use of the media
does not exceed the BOD, COD, and TSS which would be discharged if the
3-4
product were not being used and the grease trap was being properly
maintained. pH levels must be between 6 and 9.
o All testing designed to satisfy the criteria set forth in Section 3.6.3 shall be
scientifically sound and statistically valid. All tests to determine oil and grease,
TSS, BOD, COD, pH, and other pollutant levels shall use appropriate tests which
have been approved by the Environmental Protection Agency and the Texas
Commission on Environmental Quality and which are defined in Title 40, Code of
Federal Regulations, Part 136 or Title 30, TEXAS ADMINISTRATIVE CODE §319.11.
Testing shall be open to inspection by the POTW and shall meet the POTW's
approval.

4. SCHEDULE OF PENALTIES
• If the POTW determines that a generator is responsible for a blockage of a collection system
line the generator shall receive a certified letter for the first violation with five days to comply,
$1,000 for the second violation, and $1,500 for the third violation within a two-year period.
Continuous violations shall result in an increase in penalty by $500 and may also result in
termination of services.
Any person violating any of the provisions of the Ordinance shall be subject to a certified
written warning for the first violation with five days to comply, a $1,000 civil penalty for the
second violation, a $1,500 civil penalty for the third violation, and a $2,000 civil penalty for
the fourth violation within a two-year period. Consistent violations will result in a $500
increase in civil penalty and may result in termination of service.
