ISSUE
Wastewater Discharge Permit Contracts for Class I Industrial Users (permit contract) must be approved
by the Board of Directors.
BACKGROUND
Acme's pretreated landfill leachate has been accepted by Central San since the early 1990s and through
permit contracts since 1994. A permit contract was used to protect Central San and to preserve the right to
modify the discharge conditions or stop receiving the treated leachate. Central San chose to receive the
leachate after encouragement from the Regional Water Quality Control Board (RWQCB) because Central
San's acceptance of the leachate under strict conditions provided the best regional environmental
solution.
During the term of the current permit contract, Acme has operated the Leachate Treatment Plant (LTP) in
compliance with the conditions of the permit contract except for one limit violation for cyanide, one limit
violation for Total Suspended Solids (TSS) daily maximum, one limit violation for TSS monthly average
limit, and one violation for Polychlorinated Biphenyls (PCB) prohibition when PCB Aroclors were detected.
These limit violations were documented prior to June 2016. Notices of Violation (NOV) were issued for all

of these limit violations. Acme responded to the PCB citations for discharge limit violations identifying
concerns about the quality of the analytical data. Evaluation of the PCB congener data for the same
sampling event did not identify a comparable increase in PCB congeners. The cyanide limit violation was
investigated and a source was not identified. Acme was also cited using Warning Notices for four
instances when monitoring requirements were not met: Chemical Oxygen Demand samples exceeded
hold time twice, the Environmental Protection Agency (EPA) Method 625 sample diluted which impacted
the quality of data reported, and the Whole Effluent Toxicity sample was not analyzed using
the appropriate method. Central San will monitor the effluent mercury data submitted by Acme to ensure a
trend does not develop.
The proposed permit contract maintains the protections in the previous permit contract, addresses certain
changes requested by Acme representatives to reduce their compliance costs, and includes modifications
in response to the input received from the United States EPA contractors during a recent Pretreatment
Compliance Audit that included a review of the permit contract issued to Acme. Central San staff believes
that these changes are acceptable and do not significantly increase the risk to our facilities from the Acme
discharge.
As with the previous permit contract, the proposed permit contract includes conditions that allow Central
San to change the leachate monitoring parameters or effluent limits to protect Central San facilities and
operations, or to meet new regulatory requirements. Central San also has the right to suspend or terminate
the leachate discharge if acceptance of the treated leachate affects Central San's ability to meet National
Pollutant Discharge Elimination System limits, results in Central San's treatment plant being classified as a
hazardous waste treatment facility, or affects Central San's ability to reclaim water.
Staff has concluded that approval of this contract is exempt from the California Environmental Quality Act
(CEQA). Central San CEQA Guidelines Section 15308 provides an exemption where a regulatory agency
which is authorized by state or local ordinance to assure the maintenance or protection of the environment
takes action to affect such a purpose. The execution of a permit contract with Acme is intended to maintain
and protect the waters and other aspects of the environment. Approval of this contract will establish the
Board of Directors' independent finding that this contract is exempt from CEQA.
ALT ERNAT IVES/CONSIDERAT IONS
Two alternatives to the proposed permit contract were considered: 1) discontinue accepting the treated
leachate; or 2) authorize the discharge of treated leachate through Central San's existing Class I I
Industrial User Permit Program instead of a special permit. Neither alternative is preferred over the
proposed permit contract. Acme has limited options to properly dispose of the landfill leachate generated.
The permit contract gives Central San more ability to customize the requirements over the Class I I
Industrial User Permit.
FINANCIAL IMPACTS
No adverse financial impacts are anticipated from entering into this contractual agreement with Acme.
Environmental Compliance, Laboratory, and legal costs will be recovered as billable activities. Treatment
Plant and Collection System costs will be recovered through the sewer service charge authorized in the
permit contract.
COMMITTEE RECOMMENDATION
Staff reviewed the proposed changes to the permit contract at the November 27, 2017 Real Estate,
Environmental & Planning Committee meeting. The Committee identified/did not identify general support
for recommended changes and maintenance of the other permit contract elements.
