From: Michael J. Bajorek, Interim Director of Public Works and Utilities
Prepared by: Leon Holt, Utilities Pretreatment Manager
Approved by: William B. Coleman, Jr., Town Manager
Approved by: Benjamin T. Shivar, Assistant Town Manager
The North Carolina Department of Environment and Natural Resources (DENR) and the US Environmental Protection Agency (USEPA) require modifications of local sewer use ordinances (SUO) from time to time. Recently, and in light of federal pretreatment program changes, DENR is mandating revisions to local pretreatment programs statewide. These changes primarily affect new federal pretreatment streamlining regulations. All of the changes proposed have been carefully reviewed by the Town’s legal staff. Listed below are changes or modifications to the Town’s pretreatment program relative to the DENR and USEPA requirements:
Fiscal Impact: None
Staff Recommendation: Staff recommends Council adopt these required changes. DENR has reviewed and approved these changes as proposed by staff.

Discharge. Any discharge at a flow rate or concentration which has a reasonable
potential to cause Interference or Pass-Through, or in any other way violates
the POTW’s regulations, local limits, or Industrial User Permit conditions.
This can include but is not limited to spills and other accidental discharges;
discharges of a non-routine, episodic nature; a non-customary batch discharge;
or any other discharges that could cause a violation of the prohibited discharge
standards contained in section 36-173 of this division.
Sec. 36-173. Prohibited discharge standards.
Unless specifically provided otherwise, the prohibited discharge standards set forth in this section shall apply to all users of the POTW, including significant industrial users and users subject to national, state or local pretreatment standards or requirements.
(1) General prohibitions. No user shall discharge wastewater into the POTW, directly or indirectly, which causes interference or pass-through.
(2) Specific prohibitions. No user shall discharge wastewater into the POTW that contains, or has the characteristics of, the following:
a. Pollutants which create a fire or explosive hazard in the POTW, including, but not limited to, wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit (60 degrees Celsius) using the test methods specified in 40 CFR 261.21, as amended from time to time.
b. Solid or viscous substances which may cause obstruction of the flow in a sanitary sewer or the POTW resulting in interference. This includes, but is not limited to, grease, garbage with particles greater than one-half inch (1/2") in any dimension, animal guts or tissues, paunch manure, bones, hair, hides or fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, waste paper, and wood.

the POTW, collection system, or equipment. Any pH above 12.5 is considered
hazardous under 40 CFR 261.22.
(3) Storage of substances/action by director. Pollutants, substances, wastewater, or other wastes prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the POTW. All floor drains located in process or materials storage areas must discharge to the user's pretreatment facility before connecting with the POTW. When the director determines that a user is contributing or discharging to the POTW any pollutant or wastewater which causes interference or pass-through or is contributing or discharging any of the pollutants, substances or wastewater that violate the prohibitions set forth in (2) above, the director may:
a. Advise the user of the potential impact of the contribution on the POTW in accordance with section 36-179 of this division; and
b. Take
appropriate action, in accordance with section 36-1758 of
this division, requiring such user to protect the POTW and sewer collection
system from interference, pass-through, blockages, and structural or mechanical
failure.
(5) Industrial waste survey and local limits. An industrial waste survey is required prior to a user discharging wastewater containing in excess of the following average discharge limits. Industrial waste survey information will be used to develop user-specific local limits when necessary to ensure that the POTW's maximum allowable headworks loading is not exceeded for particular pollutants of concern.
Industrial
Waste Survey information will be used to develop user-specific local limits when
necessary to ensure that the POTW's maximum allowable headworks loading are not
exceeded for particular pollutants of concern. User-specific local limits for
appropriate pollutants of concern shall be included in wastewater permits. The

(9) Pretreatment of wastewater.
a. Pretreatment facilities. Users shall provide wastewater treatment as necessary to comply with this division and wastewater permits issued under section 36-175(b) of this division, and users shall achieve compliance with all national categorical pretreatment standards, local limits, and the prohibitions set out in section 36-173 of this division within the time limitations specified by the EPA, the state, or the director, whichever is more stringent. Any facilities necessary for compliance (pretreatment facilities) shall be provided, operated, and maintained at the user's expense. Detailed plans showing the user's pretreatment facilities and operating procedures shall be submitted to the town for review, and shall be approved by the director before construction of the facility. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the town under the provisions of this division. Any subsequent changes in the pretreatment facility or its method of operation shall be reported to, and be approved by, the director prior to the user's initiation of the changes.
b. Additional pretreatment measures.
1. Whenever the director deems it necessary, the director may require users to restrict their discharge during peak flow periods; designate that certain wastewater be discharged only into specific sewers; relocate and/or consolidate points of discharge; separate sewage wastestreams from industrial wastestreams; and require such other conditions as may be necessary to protect the POTW or to determine the user's compliance with the requirements of this division.
2. The director may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow control facility to ensure equalization of flow. The director may issue a wastewater discharge permit solely for flow equalization.
3. 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 and oil, or sand, except that such interceptors shall not be required for residential users. All interception units shall be of a type and capacity approved by the director and shall be so located as to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned and repaired regularly, as needed, by the user at the user's expense. See also section 36-183 for additional requirements.
4. Users with the potential to discharge flammable substances may be required to install and maintain one or more approved combustible gas detection meters.
(10)
Accidental discharge/slug control plan.
At least once every two years the director shall evaluate whether each
significant industrial user needs an accidental discharge/slug control plan. The
director may require any user to develop, submit for approval, and implement
such a plan. Alternatively, the director may develop such a plan for any user.
An accidental discharge/slug control plan shall address, at a minimum, the
following: The Director shall evaluate whether each significant
industrial user needs a plan or other action to control and prevent slug
discharges and accidental discharges as defined in section 36-172, Definitions.
All SIUs must be evaluated within one year of being designated as SIU. The
Director may require any user to develop, submit for approval, and implement
such a plan or other specific action. Alternatively, the Director may develop
such a plan for any user. All SIUs are required to notify the POTW immediately
of any changes at its facility affecting the potential for spills and other
accidental discharge, discharge of non-routine, episodic nature, a non-customary
batch discharge, or a slug load. Also see section 36-176(e)(f).
An accidental discharge/slug control plan shall address, at a minimum, the following:
Sec. 36-174. Fees.
(a) Purpose. It is the purpose of this division to provide for the recovery from users of the town's wastewater disposal system of costs of the POTW and for the implementation of the program provided for herein. The applicable charges or fees shall be set forth in the town's schedule of charges and fees.
(b) User charges. A user charge shall be levied on, and paid by, all users.
(1) The user charge shall reflect, at a minimum, the cost to the town of debt service, and operation and maintenance costs (including, but not limited to, replacement costs) of the POTW.
(2) Each user shall pay its proportionate share of cost based on the volume of the user's flow.
(3) The town manager shall review annually the sewage contributions of users, the total costs of debt service, and operation and maintenance costs of the POTW (including, but not limited to, replacement costs) and shall make recommendations to the town council for adjustments in the schedule of charges and fees as necessary.

(g) Reports from unpermitted users. All users not required to obtain a wastewater discharge permit shall provide appropriate reports to the director as the director may require.
(h)Notice
of violation/repeat sampling and reporting.
If sampling performed by a user indicates noncompliance or any other violation,
the user must notify the director within 24 hours of becoming aware of the
violation. The user shall also immediately repeat the sampling and analysis and
submit the results of the repeat analysis to the director within 30 days after
becoming aware of the violation. If allowed by the Director, Tthe
user is not required to resample:
1.
iIf the director monitors at the user's facility at least
once a month,
2.
or iIf the director samples between the user's initial
sampling and the time when the user receives the results of this sampling.
(i) Control Authority repeat sampling in lieu of permittee self-monitoring. If the director does not require user to perform any self-monitoring and the POTW sampling of the user indicates a violation, the Director shall repeat the sampling and obtain the results of the repeat analysis within thirty (30) days after becoming aware of the violations, unless one of the following occurs:
1. The Director monitors at the user’s facility at least once a month; or
2. The Director samples the user between their initial sampling and when the POTW receives the results of this initial sampling; or
3. The Director requires the user to perform sampling and submit the results to the Director with the 30 day deadline of the POTW becoming aware of the violation.
(i)(j)
Notification of discharge of hazardous waste.
(j)(k)
Analytical requirements. All pollutant analyses, including sampling
techniques, to be submitted as part of a wastewater discharge permit application
or report shall be performed in accordance with the techniques prescribed in 40
CFR 136, unless otherwise specified in an applicable categorical pretreatment
standard. If 40 CFR 136 does not contain sampling or analytical techniques for
the pollutant in question, sampling and analyses must be performed in accordance
with procedures approved by the EPA.
(k)(l)Grab
and composite
Ssample
collection.
(1) Except as
indicated in subsection (k)(2) below, the user must collect wastewater samples
using flow proportional composite collection techniques. In the event the
director determines that flow proportional sampling is not feasible, the
director may authorize the use of time proportional sampling or minimum of four
grab samples where the user demonstrates that this will provide a representative
sample of the effluent being discharged. In addition, grab samples may be
required to show compliance with instantaneous discharge limits.
(2) Samples for
oil and grease, temperature, pH, cyanide, phenols, sulfides, and volatile
organic compounds must be obtained using grab sampling techniques.
(i) All wastewater samples must be representative of the user’s discharge. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of a user to keep its monitoring facility in good working order shall not be grounds for the user to claim that sample results are unrepresentative of its discharge.
(ii) Grab Samples must be used for temperature, pH, cyanide, total phenols, oil and grease, sulfide, volatile organic compounds, and any other pollutants as required by 40 CFR 136. The POTW shall determine the number of grabs necessary to be representative of the User’s discharge. See 40 CFR 403.12(g)(5) for additional grab sample number requirements for BMR and 90 Day Compliance Reports. Additionally, the [POTW Director] may allow collection of multiple grabs during a 24 hour period which are composited prior to analysis as allowed under 40 CFR 136.
(iii) Composite Samples: All wastewater composite samples shall be collected with a minimum of hourly aliquots or grabs for each hour that there is a discharge. All wastewater composite samples shall be collected using flow proportional composite collection techniques, unless time-proportional composite sampling or grab sampling is authorized by the [POTW Director]. When authorizing time-proportional composites or grabs, the samples must be representative and the decision to allow the alternative sampling must be documented.
(l)(m)Timing.
Written reports to the director shall be deemed to have been submitted on the
date postmarked. For reports which are not deposited, postage prepaid, into a
mail facility serviced by the United States Postal Service, the date of receipt
of the report by the director shall govern.
(m)(n)Recordkeeping.
Users subject to the reporting requirements of this division shall retain, and
make available for inspection and copying, all records of information obtained
pursuant to any monitoring activities required by this division and any
additional records of information obtained pursuant to monitoring activities
undertaken by the user independent of such requirements. Records shall include:
(1) The date, exact place, method, and time of sampling;
(2) The name of the person(s) taking the samples;
(3) The dates analyses were performed;
(4) Identification of the person(s) who performed the analyses;
(5) The analytical techniques or methods used; and
(6) The results of such analyses.
These records shall remain available for a period of at least three (3) years. This period shall be automatically extended for the duration of any litigation concerning the user or the town, or where the user has been specifically notified of a longer retention period by the director.
(o) Electronic Reporting. The Director may develop procedures for receipt of electronic reports for any reporting requirements of this ordinance. Such procedures shall comply with 40 CFR Part 3. These procedures shall be enforceable under section 36-179.
