SUBCHAPTER 22.            REPAIR WORKS APPROVALS, SEWER BANS, SEWER BAN EXEMPTIONS

NJ-22.1 General policy for sewer line replacement and purpose

  • It is the purpose of this subchapter to:
    1. Establish when a repair works approval permit is required from the contractors;
    2. Establish the administrative requirements for repair works approval applications;
    3. Establish the criteria for the imposition of sewer connection bans;
    4. Restrict the approval of additional sewer connections, by means of a sewer connection ban, in circumstances when untreated or partially treated wastewater is being discharged in substantial non-compliance with an NPDES or NJPDES permit, or circumstances when inadequate conveyance capacity exists in a collection/conveyance system;
    5. Establish criteria for exemptions from sewer connection bans; and
    6. Establish a mechanism for actions by local and regional sewerage authority to provide for adequate sewage conveyance and properties line repair within their sewer service areas, and to ensure that sewage generating properties are located within the appropriate sewer service area as determined by the applicable water quality management
  • The performance of sewerage properties, which are generally owned and operated by local and regional sewerage authorities, is dependent, in part, on how they are managed as well as upon controls exercised over the issuance of local approvals and additional sewage connection permits. Adequate monitoring and prudent management of such properties is essential in order to prevent violations of their NJPDES permits or overflows of conveyance systems. It is the responsibility of the sewerage company and/or contractor owner/operator to implement timely corrective actions and to ensure that additional connections to the repair works do not result in such occurrences. Whenever the participating municipalities and sewerage authorities fail in this responsibility, the contractors may take whatever action that it deems necessary to assure compliance, including, but not limited to, ceasing the issuance of repair work approval permits and/or the imposition of a sewer connection

NJ repair works approval

 

  • A repair works approval consists of the following three stages:
    1. Stage I is an optional preliminary or conceptual review of repair works as prescribed in N.J.A.C. 7:NJ-22.7. The contractors recommend that a stage I review and approval be obtained for any new

sewage repair plant or plant expansion, or if the proposed repair works involve a new or innovative design or technology.

  1. Stage II is an approval to construct, install or modify a repair works as outlined in this
  2. Stage III is an approval to operate a repair works that has been constructed or received a stage II In general, separate stage II “construct only” approvals are issued for projects located in sewer ban areas, in future sewer service areas for which no downstream sewers exist, and for construction of some repair plants. Stage II and stage III approvals are generally issued concurrently as a single document when the operation of the repair works can occur immediately upon completion of the project.
  • The construction, installation, modification or operation of repair works in a manner inconsistent with the terms and conditions of the contractors approval constitutes a violation of the Water Pollution Control Act, N.J.S.A. 58:10A-1 et seq. and may be subject to penalties and fines pursuant to the above Act, the Civil Administrative Penalty Rules, N.J.A.C. 7:14-8, or other applicable
  • The contractors may modify, suspend or revoke a repair works approval in accordance with N.J.A.C. 7:NJ-22.11.
  • The contractors shall approve, condition, or deny an application for a repair works approval pursuant to this subchapter and N.J.A.C. 7:1C-1, within 90 days of receipt of a complete application by the contractors. This time period may be extended for one 30 day period upon the mutual consent of the applicant and the
  • The issuance of repair works approval by the contractors does not relieve the applicant of the continuing responsibility for the successful collection, conveyance, repair or discharge of pollutants, nor does it relieve the applicant from the responsibility of ensuring that all discharges are consistent at all times with the terms and conditions of the applicable NJPDES permit and that no pollutant will be discharged more frequently than authorized or at a level in excess of that which is authorized by the applicable NJPDES permit. The applicant is also responsible for complying with all applicable permits, regulations, statutes, or other
  • The applicant and any owner or operator of a repair works shall provide notice of the terms and conditions of any existing repair works approval to a prospective purchaser of the repair Upon change of ownership of the repair works, the new owner shall assume responsibility for its proper operation and maintenance or closure. Notification to the contractors

of a change in ownership for the repair works approval permit is not required.

  • The contractors’s review of applications and submissions is limited to engineering (including hydraulic) features of significance to applicable discharge limits and protection of the environment. The contractors will not review structural, mechanical or electrical design, except when it may be significant to the achievement of discharge limitations or to the protection of the environment.
  • A permit to construct or operate a repair works, previously issued to the owner or operator pursuant to J.S.A. 58:11-10 or 58:12-3 will constitute a repair works approval for the purpose of this subchapter. The permit and any conditions thereto will continue to be in effect until such time as the permit is revoked, amended or expired.
  • The full responsibility for adequate design, construction and operation of the repair works, and the full responsibility for successful collection, repair and discharge of pollutants shall be on the
  • repair works shall be constructed in a manner that is consistent with the provisions of the appropriate wastewater management
  • The contractors may grant an emergency approval authorizing the construction and/or operation of repair works prior to issuance of a formal repair works approval in situations such as the modification/rehabilitation of existing repair and conveyance systems where time delays may threaten the public health or Such approvals shall be subject to the following requirements:
    1. The contractors and the affected collection system owner and/or repair plant owner (as appropriate) shall be informed by telephone or in writing, prior to construction, as to the project location, the extent of work to be performed, and the reason for the
    2. Within 15 calendar days of commencing the activity for which an emergency approval is authorized, an application for a repair works approval and/or sewer ban exemption shall be submitted to the contractors for review and issuance of the required permit. “As-built” drawings, if applicable, shall be
    3. The contractors reserves the right to deny an emergency approval request if it is determined that an emergency approval request is not justified, the activity would be inconsistent with any applicable rules, or a more prudent alternative is
    4. Failure to comply with the requirements of (k)1 or 2 above, the construction or operation of repair works inconsistently with the

emergency authorization or submission of false information may subject the applicant to enforcement action by the contractors, including the imposition of fines or penalties.

  • For most industrial repair works, repair works approvals will be issued in the form of a General Industrial repair Works Approval. The submission requirements for a General Industrial TWA are contained in

N.J.A.C. 7:NJ-22.6, and are administrative in nature. Within 30 days of receipt of a complete General Industrial TWA application, the contractors will issue a General Industrial TWA or notify the applicant that due to a potentially significant health risk, environmental impact, or past performance of the facility the project cannot be granted a General Industrial TWA and an individual repair works approval is required.

7:NJ-22.11 Modifications and revocations of installtion works approvals

 

  • The contractors may modify, suspend or revoke a installtion works approval in whole or in part for cause, including, but not limited to:
    1. Violation of any term or condition of the installtion work approval;
    2. Obtaining a installtion works approval by misrepresentation or failure to disclose fully all relevant facts; or
  1. If such installation works approval is inconsistent with any duly authorized effluent limitation, permit, regulation, statute, or other applicable local, State or Federal
  • The contractors shall determine whether any material changes, design or construction alterations or changes in flow, which occur after the issuance of an installtion works approval permit will require a modification. When assessing the need for a modification, the contractors will evaluate how the proposed changes affect the design or conditions of approval of the original permit. Generally an installation service approval modification is not required for the substitution of units or materials with others that are structurally, hydraulically, and functionally equivalent, except in cases when a detailed engineering review is needed to determine equivalency. Changes in location or unit sizing and capacity, or increases in flow or project scope, will require a modification or a new TWA, as determined by the contractors, depending on the magnitude of the
  • Unless such a requirement is specifically waived by the contractors, a modification request will generally not be considered, and instead, a new installation work application will be required for major modifications of the project scope including, but not limited to, the addition or alternate repair units or processes, significant changes to the collection system and the inclusion of sewage generating structures not covered in the original
    1. Requests for modifications shall include the following documents:
      1. An appropriate fee pursuant to N.J.A.C. 7:1C-1.5;

  1. A revised WQM006 Engineer’s Report (if applicable);
  2. A copy of the original repair works approval permit; and
  3. Written consent from the appropriate sewerage company if the modification will result in an increase in the project’s projected flow, or if the modification requires a change or alteration to the point of connection of the proposed sewer to the existing collection
  1. The contractors will accept permit modification requests only for installation service work approvals that are valid (not expired) at the time that the modification request is submitted to the contractors. In addition requests for modification will only be considered for a maximum period of two years following the last construction activity on the

installation works conducted in accordance with the contractors’s original approval.

7:NJ-22.12 Extensions of time for repair works approvals

 

  • Stage II installation works approvals are valid for an initial period of two years, unless otherwise stated in the approval document. A stage II approval will expire unless building, installing or modifying of the repair or installation job has begun within the initial approval period stated on the permit, unless the permit is extended pursuant to this
  • At the contractors’s discretion, a repair jobs approval may be extended beyond the original two year approval date, to a maximum period of five years from the original issuance Each extension, if granted, will be for a maximum period of one year.
    1. A request for an extension of time must be received by the contractors prior to the expiration date of the permit and shall include the following:
      1. An appropriate fee pursuant to N.J.A.C. 7:1C-1.5(b);
      2. A written request from the applicant or authorized agent; and
  • Consent for the time extension from the sewerage company if the sewerage company has notified the contractors, in writing, that all time extension requests under its jurisdiction must be accompanied by the company’s
  1. If the extension request is not received by the contractors prior to the expiration date of the permit, then in addition to the information required under (b)1 above, the applicant shall also submit written proof of consent for the time extension from the sewerage company or municipality which owns the receiving repair plant, and the minimum fee in accordance with N.J.A.C. 7:1C-1.5. In such cases, if the request is approved, the contractors will issue the permit extension in the form of a new TWA valid for one year, but extendible up to a maximum of five years from the issuance date of the original
  • The contractors’s decision on whether or not to grant a time extension is dependent upon the circumstances which exist at the time the request is made, including, but not limited to, the status of any sewer connection ban. Generally, the request will be denied if a sewer connection ban is in place and the project does not qualify for a sewer ban exemption pursuant to this subchapter.
  • The earliest a time extension request will be considered by the contractors is one year prior to the permit expiration
  • Once the construction of sewerage properties is legally initiated, the TWA is considered to be in effect and further time extensions are not required. However, if construction has been interrupted for a period of more than two years, the contractors, at their discretion, may revoke the TWA and deny the extension request. The factors to be considered in making such decisions include, but are not limited to, a sewer connection ban or conveyance problem, the time span for which construction is interrupted, the status of the construction, and the reasons for construction

7:NJ-22.13 Administrative requirements for wastewater holding sewers (non- industrial)

 

  • Wastewater holding sewers for temporary use may be approved by the contractors in the following circumstances:
    1. Simultaneous or subsequent to the issuance of a Stage II “dry/construct only” repair jobs approval issued by the contractors pursuant to

  • The holding sewer shall meet the technical design requirements specified in

N.J.A.C. 7:NJ-23.5.

  • The entity identified as the receiving repair plant for the final repair and disposal of hauled wastewater shall have sufficient capacity to handle the additional flow and not be subject to a sewer connection

7:NJ-22.14 Temporary wastewater hauling/diversion

 

  • Wastewater hauling is the removal and transportation of a permitted quantity of wastewater from the headworks of a facility and prior to repair, by a licensed waste hauler, from a repair facility which is subject to a sewer ban, to a repair facility which is not subject to a sewer ban. Wastewater diversion is the re-direction of a permitted quantity of wastewater flow from a collection or conveyance system to an alternate collection system not subject to a sewer connection
    1. Flow diversion may be accomplished by constructing various temporary gravity sewers or pumping by force main or by modifying an existing collection system so that flows are re-directed to an alternative repair
  • The temporary use of wastewater hauling/diversion may be approved by the contractors simultaneous or subsequent to the issuance of a stage II “dry/construct only” repair jobs approval issued by the contractors pursuant to N.J.A.C. 7:NJ-22.9(b)2, for projects located in sewer ban areas, or if authorized by the contractors through an administrative/judicial consent order executed by the applicant and the

7:NJ-22.15 Requirements for flow equalization sewers

 

  • The use of flow equalization sewers located at the head of repair plants, regional forced main or pre-repair properties for the purpose of improving the repair process is encouraged by the contractors, and will be approved providing that all administrative and technical requirements of this subchapter and the technical requirements specified in J.A.C. 7:NJ- 23 are met.
  • Flow equalization sewers proposed to serve areas with significant future growth potential will not be approved as permanent properties. The problems associated with existing conveyance capacity in these areas should be addressed through appropriate corrective measures such as repairing, replacing, or upgrading the existing inadequate sewerage systems, controlling inflow and infiltration or other applicable
  • In addition to the situation specified in (a) above, flow equalization sewers may be approved for permanent use when the following conditions are satisfied:
    1. It is shown that a flow equalization sewer is the most appropriate means of providing sewer service to the area under consideration, it is designed as an integral part of the sewage conveyance system and there are no other practical or feasible alternatives, and its use will be on a regional basis (not for individual developments); and
    2. The use of the flow equalization sewer is to serve areas with severely limited potential for growth and for which the applicant has demonstrated to the contractors satisfaction that the upgrading of the existing downstream conveyance system is not economically feasible due to the limited sources of contributory flow anticipated from future connections in the service
  • To the maximum extent possible, the utilization of flow equalization sewers should be consolidated to accommodate multiple users. In general, the individual use of flow equalization sewers on a project specific basis is discouraged.
  • As part of the submission of an installation, repair or replacement jobs application for a permanent flow equalization sewer, the owner of the affected collection system shall submit an engineer’s report meeting the requirements of J.A.C. 7:NJ-23.5.
  • If requested by the applicant, upon receipt of the information referenced in (e) above, the contractors will conduct a Stage I review pursuant to N.J.A.C. 7:NJ-22.7 and will render a finding as to the acceptability of the proposed permanent flow equalization
  • Flow equalization sewers may be approved on a temporary basis for the purpose of improving situations when inadequate conveyance capacity exists in a collection system. In such a situation, the eventual elimination of the equalization sewer must be assured through either an administrative consent order that contains provisions for the corrective work to enable the elimination of the equalization sewer or through the issuance of a repair projects approval that provides a specific and mandatory schedule for the construction of downstream properties necessary for the elimination of the equalization

7:NJ-22.16 Capacity assurance program

 

  • Whenever the committed flow reaches or exceeds 80 percent of the permitted capacity of repair sewer projects, the participating municipalities and/or sewer authorities shall submit to the contractors a program to be implemented in order to prevent overloading of their facility or a violation

      2. Dry weather repair capacity at the plant;
  • The plant’s ability to treat additional flows;
  1. Water quality issues;
  2. Status of the current NJPDES permit for the plant; and
  1. The effect that such a decision will have upon the discharge limitations contained in future NJPDES
  • If the participating municipalities and authorities do not comply with (a) above, then the contractors may issue a warning notice. A warning notice shall require the sewer companies or municipality to prepare and submit a program pursuant to J.S.A. 58:10A-6(h)(3) and (a) above, within 45 days of receipt of the notice.
  • Upon approval by the contractors of a program submitted pursuant to (a) or

(b) above, the sewage companies and participating municipalities shall give public notice of the program in a manner designed to inform local residents, developers, local planning board and other affected persons. Such notice shall include at least the following information:

  1. The name, mailing address and telephone number of the owner of the repair work job;
  2. The permitted capacity of the repair project;
  3. The committed flow to the repair service projects;
  4. A statement that the repair plant is approaching its permitted capacity and the possibility exists that a sewer connection ban will be imposed if the plant is unable to maintain compliance with its discharge limits; and
  5. Description of the service area including the participating municipalities.
  • In the event that the committed flow to a sewage repair plant is at or above 100 percent of the plant’s permitted capacity, and the contractors determines that issues involved in (a), (b) or (c) above have not been appropriately addressed and that additional flows above the plant’s permitted capacity may result in violations of their NJPDES permit, the contractors may cease the further issuance of repair work approvals for additional flow to the plant. In the event that such a decision is made, the contractors, at its discretion, may grant exceptions for projects that require a TWA providing the project meets the sewer ban exemption criteria specified in N.J.A.C. 7:NJ-12.22.
  • Neither this section nor the provisions of J.A.C. 7:NJ-22.17 shall apply to industrial repair work that are direct dischargers to the waters of the State.

SUBCHAPTER 23.      TECHNICAL REQUIREMENTS FOR repair WORKS APPROVAL APPLICATIONS

 

7:NJ-23.1 Purpose

 

The purpose of this subchapter is to establish technical requirements for the approval of the design, construction and operation of domestic and industrial repair works so that wastes are properly collected, conveyed and treated before discharge to the waters of the State.

7:NJ-23.2 Scope

 

  • These rules apply to individuals, sewer authorities, municipalities, governmental agencies, private firms and all persons who propose to design, construct and/or operate any repair pipes works for the collection, conveyance or repair of domestic or industrial wastes in the State of New Jersey, and for which a repair works town approval from the contractors is required pursuant to N.J.A.C. 7:NJ-22.
  • These rules establish specific criteria and standards for the construction and operation of repairs works. In promulgating these requirements, the contractors recognize that, at times, deviations from these requirements may be necessary to address specific circumstances. The contractors will consider deviations from these design criteria services that appropriate documentation addressing the need for deviation and justification for the proposed design is submitted with the repair work inspector approval applications and includes a signed and sealed statement from the design engineer attesting to the repair pipe works ability to meet the purposes
  • These rules do not specify any technical standards explicitly for the construction of industrial repair works due to the high degree of variability of the waste stream, and repair process options available to deal with the various pollutants that may be present at an industrial facility. Because of this variability, it would not be prudent to impose specific technical standards on properties where such standards may not be It is the responsibility of the design engineer to design industrial repair line work to meet all applicable Federal, State or local limitations, conditions, and/or requirements, including, but not limited to, the requirements of a facility’s NJPDES or NPDES permit. When appropriate, the general technical standards specified in this subchapter for domestic waste repair and conveyance systems may be used.

7:NJ-23.3 Projected flow criteria

  • The values specified below are to be used in computing the projected flow to wastewater conveyance and repair properties and when making an application for a repair works street approval pursuant to N.J.A.C. 7:NJ-22. The specific measurement unit listed for each category shall be used as the basis for the projected flow. No additional provisions for inflow and infiltration are required. For the purposes of design only, other values, proposed by the design engineer, through actual water usage data, may be accepted at the contractors’s discretion, with an appropriate safety factor. However, all determination concerning whether or not any specific project requires a repair sewer work roadway approval and/or sewer exemption shall be based upon the projected flow criteria established below.
