Engineering/Construction ISSUE: The Grit Line will be $17,000.00 rather than $10,000.00 for the proposed Grit Handling Facility. BACKGROUND: The District Board approved a $10,000.00 expenditure for the District to construct a Grit Line during dry weather. After receiving quotations for various items of work, we have determined that the Grit Line will cost $7,000.00 more than originally estimated. The increase is due to added special pipe coatings, added valves and increased core drilling through existing concrete tank walls. A request to the State Water Resource Control Board has been made for grant funding for this work. RECOMMENDATION: Authorize an additional $7,000.00 for a total of $17,000.00 on Grit Line Project No. 3574.

Barker INITIATING DEPT./DIV. Engineering/Construction ISSUE: Since the Contractor, Power-Anderson, Inc, has satisfactory completed construction of the project, the project is ready for acceptance by the District. While performing the work required by the Contract, the Contractor performed extra work exceeding the estimated contingency. BACKGROUND: On June 4, 1981, District entered into an agreement with Power- Anderson, Inc. for the Natural Gas Line Relocation, Project No. 3516. The Contractor satisfactorily completed all construction work on August 6, 1981, including all change order and punch list items. The Contractor performed $7,479.60 in extra work while performing the Contract. The actual extra work was 14 percent rather than the estimated 10 percent for contingency. The additional 4 percent was due to the underground abandoned pipe and utilities not shown on the plans because the Treatment Plant does not have as-built drawings. RECOMMENDATION: The following Board actions are recommended: 1. Authorize an additional $2,604.60 for Account No. 51010.3516 to cover the extra work. 2. Accept contract work for Project No. 3516. 3. Authorize filing Notice of Completion with the Contra Costa County Recorder. 4. Authorize final payment to the Contractor 35 days after the Notice is filed provided no claims are received.

McCoy INITIATING DEPTjDIV. Engineering Collection System SUBMITTED BY ISSUE: The Regional Board has required that all dischargers in the San Francisco Bay Region develop pretreatment programs which will reflect the new Federal pretreatment guidelines. BACKGROUND: In 1974, this District adopted an Industrial Waste Ordinance which is still in effect. In September, 1980, the Regional Board adopted Board Order No. 80-44 which established new pretreatment regulations for 30 bay area sewering agencies. Each of the affected agencies is required to develop a Pretreatment Ordinance to reflect the requirements contained in EPAls General Pretreatment Regulations. The existing CCCSD Industrial Waste Ordinance has been completely reorganized and updated in addition incorporating the required changes. Some of the major additions or modifications are high-lighted below: 1. Industrial users are required to comply with applicable Federal Pretreatment Standards as the Standards are pro- mulgated. 2. A requirement is included for each industrial user to develop a compliance schedule where additional equipment or measures are required to meet applicable Pretreatment Standards. 3. Specific language has been added to effectively eliminate the discharge of pollutants to the treatment plant which may present an imminent or substantial endangerment to the health or welfare of persons,to the environment, or cause inter- ference with the operation of the treatment plant. 4. A procedure is included for updating of the Pretreatment Ordinance to comply with evolving Federal Law. 5. The District will randomly sample and analyze effluent from industrial users and conduct inspection activities. 6. The existing limitations or concentrations of heavy metals, hydrocarbons and phenols are modified to more appropriately reflect the limitations which other bay area agencies have establ ished. 7. A requirement for the installation of facilities to protect against accidental discharge of prohibited materials is included. Page 1 of 2 REVIEWED AND RECOMMENDED FOR BOARD ACTION TING DEPT./DIV. //n4 -2- 8. The requirement for submission of periodic compliance reports by industrial users to the District is increased from once a year to twice a year. 9. Penalties for non-compl iance have been reduced from $6000 per day to a maximum of $1000 per day. Copies of the draft pretreatment ordinance and notice of public hear- ing have been sent to each of the industries currently included in the District's source control program, the Regional Water Quality Control Board, the City of Concord, the Bay Area League of Industrial Associations and the Naval Facilities Engineering Command (Concord Weapons Station) for comments. Appropriate legal notices have been published in the newspaper. Any comments received to date have been incorporated into the attached document and/or are attached to this position paper. District counsel has also reviewed and commented on the draft ordinance. In accordance with the Board's action on August 6, 1981, this public hearing is being conducted to provide interested and affected persons the opportunity to provide comment on the new ordinance. If no significant public comments are presented, the Board of Directors should now consider adoption of the Pretreatment Ordinance in the current form. If significant public or Board issues are raised, the Pretreatment Ordinance should be referred back to staff for possible revision with ftnal adoption to be considered at a later date. RECOMMENDATION: Conduct public hearing and receive comments. Consider final adoption of Pretreatment Ordinance unless significant comments are presented warranting additional staff review.

Ansl'med C<~;: ....:""'CT'.'-""'" '"""",',,,",,' FACT SHEET .RETREATMENT (SOURCE CONTROL) f ,RAM FOR THE CENTRAL CONTRA COSTA SANITARY DISTRICT (CCCSD) INTRODUCTION: The Environmental Protection Agency (EPA) of the Federal Govern- ment requires the implementation of a pretreatment program as a condition for grant funding of wastewater treatment facilities and for obtaining a permit to discharge treated liquid wastes into surface waters (CCCSD discharges to Suisuin Bay). PROGRAM GOALS: The District's pretreatment program requires industries having significant levels of .certain pollutants in their wastewater to reduce the amount of pollutants, eliminate the pollutants or alter the nature of the pollutant properties to a less harmful state prior to discharging the wastewater into the public sewer system. The basic intent of the program is to prevent the introduction of pollutants which will: (1) interfere with the operation of the treatment plant or collection system; or (2) contaminate the resulting treatment process sludge; or (3) pass through the system inadequately treated into receiving waters; or (4) constitute a hazard to humans or animal life. POLLUTANTS INVOLVED IN PROGRAM: CCCSD's Industria1"Pretreatment Program prohibits the discharge of excessive concentrations of toxic or hazardous pollutants such as metals (copper, lead, mercury, etc) and certain chemicals as well as low pH (acidic) or high temperature wastewater. Radioactive wastewater and unpolluted water are examples of prohibited discharges. The Districts pretreatment ordinance includes a complete listing of restricted or prohibited discharges. C.C.C.S.D.'s EXISTING PROGRAM: The Central Contra Costa Sanitary District has had a pretreatment program in effect since April, 1975. Each new industrial user or existing industrial user who signi- ficantly modifies its operation is required to complete a questionaire. From the questionaire, the District classifies the industry as to the potential for toxic or hazardous pollutants being contained in its process wastewater. ...,.:'-<;..~"_:,"", .,.- Industries with the potential of having toxic or hazardous pollutants in their wastewater are required to obtain an annual waste- water discharge permit. The permit may require pretreatment of the wastewater by the industry prior to discharge. Every industry in- cluded in the permit program is required to monitor their wastewater and to provide an analysis of their discharge for District evaluation. Continued discharge approval is dependent upon compliance with speci- fied discharge standards contained in the annual permit. The District's current industrial waste ordinance (No. 99) contains the existing regulations and limitations for this program. Recent changes in the Federal regulations have made it necessary for the District to update its ordinance. C.C.C.S.D. 's PROPOSED PROGRAM: Procedures contained in the existing pretreatment program as identi- fied in the previous section will be continued. There will be an in- crease in the detailed evaluation of written materials submitted and field reviews of company operations. District personnel will sample and analyze wastewater discharges from industries on a routine basis. Presently there is no monitoring by the District. A formal procedure wiil be developed for review of the need for grease interceptors for restaurants. A yearly inspection of existing restaurants will be done with the intent of eliminating grease buildups in the public sewer system before stoppages occur. Unique commercial businesses will be identified and reviewed in the field. Discharge permits will be issued as necessary. The installa- tion of pretreatment facilities will be required if toxic discharges are found. PROPOSED REVISED ORDINANCE; The District's current industrial waste ordinance has been re- written to include new Federal legislation such as requirements for industries to comply with Federal Categorical Pretreatment Standards and EPA's requirements for enforcement authority. Provisions for appropriate updating of the ordinance to include additional restrict- ive, procedural and funding language is also included. Once the re- vised ordinance has been accepted by the District Board of Directors, final approval is required from the Regional Water Quality Control Board. PROGRAM FUNDING; The District will establish a user fee schedule in the near future to provide the funding necessary to administer the required Pretreatment Program. It is anticipated that industrial dischargers will be charged an annual permit fee to cover the cost of site inspections, review of sampling procedure and chemical analysis, as well as enforcement and miscellaneous administrative type expenses. ORDINANCE NO. 147 SOURCE CONTROL (PRETREATMENT) ORDINANCE Section 8-401. General Provisions. A. Purpose and Policy. This Ordinance sets forth uniform requirements for contributors to the wastewater collection and treatment system of the Central Contra Costa Sanitary District (hereafter District) and enables the District to comply with all applicable State and Federal laws required by the Clean Water Act of 1977 and the General Pretreatment Regulations (40 CFR Part 403) on file at the District office.

A toxic pollutant shall include but not be limited to those pollutants for which effluent standards will be established. A list of toxic pollutants is on file at the District office. -5- 5. Any noxious or malodorous liquids, gases, or solids which either singly or by interaction with other wastes are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for maintenance and repair. 6. Any substance which may cause the Treatment Plant's effluent or any other product of the Treatment Plant such as residues, sludges, or scums, to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case, shall a substance discharged to the District's Facilities cause the Plant to be in non-compliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act on fi Ie at the District office. 7. Any substance which will cause the Treatment Plant to violate its NPDES Permit or the receiving water quality standards. 8. Any wastewater with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions. 9. Any wastewater having a temperature which will inhibit biological activity in the Treatment Plant resulting in interference, but in no case wastewater with a temperature at the introduction into the Plant which exceeds 400C (I04oF) unless the Treatment Plant is designed to accommodate such temperature or with a temperature at the point of discharge to the District's collection system which exceeds 650C (150oF). 10. Any pollutants, including oxygen demanding pollutants (BOD, etc.) released at a flow rate and/or pollutant concentration which a user knows or has reason to know will cause interference to the Treatment Plant. In no case shall a slug load have a flow rate or contain concentration or qualities of pollutants that exceed for any time period longer than fifteen (J 5) minutes more than five (5) times the average twenty-four (24) hour concentration, quantities, or flow during normal operation.

Any septic tank sludge unless a permit is issued by the District. 16. Any holding tank waste unless a permit is issued by the District. B. Federal Categorical Pretreatment Standards. Upon the promulgation of the Federal Categorical Pretreatment Standards for a particular industrial subcategory, the Federal Standard, if more stringent than limitations imposed under this Ordinance for sources in that subcategory, shall immediately supersede the limitations imposed under this Ordinance. The General Manager shall notify all affected users of the applicable reporting requirements under Section 8-404.B and 8-404.C of this Ordinance. C. Modification of Federal Categorical Pretreatment Standards. Where the District's wastewater treatment system achieves consistent removal of pollutants limited by Federal Pretreatment Standards, the District may apply to the Regional Water Quality Control Board for modification of specific limits in the Federal Pretreatment Standards. Samples shall be taken in accordance with the following: (I) Influent and effluent operational data shall be representative of yearly and seasonal conditions to which the Treatment Plant is subjected for each pollutant for which a discharge limit revision is proposed; (2) The data shall be representative of the quality and quantity of normal effluent and influent flow of the system; (3) The data shall be obtained through a composite sample taken on each of three (3) consecutive days during each season. Each composite sample will contain a minimum of twelve (12) discrete samples taken at equal time intervals over the twenty-four- (24) hour period and proportional to the flow. More than the minimum number of discrete samples may be required where necessary to determine Consistent Removal; (4) Where a composite sample is not an appropriate sampling technique, a grab sample shall be taken. Grab samples will be required, for example, where the parameters being evaluated are those, such as cyanide and phenol, which may not be held for any extended period because of biological, chemical or physical interactions which take place after sample collection and affect the results. A grab sample is an individual sample collected over a period of time not exceeding fifteen (15) minutes. Once prior approval is obtained from the Regional Water Quality Control Board, the District may then modify pollutant discharge limits in the Federal Pretreatment Standards. The Industrial User shall be responsible for the cost of sampling, analysis, and reporting. D. Specific Pollutant Limitations. No person shall discharge wastewater containing in excess of: 2.00 mg/I arsenic 1.00 mg/I cadmium 5.00 mg/I copper 5.00 mg/I cyanide 2.00 mg/I lead 0.05 mg/I mercury 5.00 mg/I nickel 1.00 mg/I silver 2.00 mg/I total chromium 5.00 mg/I zinc 0.50 mg/I total identifiable chlorinated hydrocarbons 10.00 mg/I phenolic compounds which cannot be removed by the District's waste- water treatment processes -7- E. State Requirements. State requirements and limitations on discharges shall apply in any case where they are more stringent than Federal requirements and limitations or those in this Ordinance. F. District's Right of Revision. The District reserves the right to establish by Ordinance more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary to comply with the objectives presented in Section 8-401.A of this Ordinance. G. Excessive Discharge. No user shall ever increase the use of process water or, in any way, attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in the Federal Categorical Pretreatment Standards, or in any other pollutant-specific limitation developed by the District or State. H. Accidental Discharges. Each user shall provide protection from accidental discharge of prohibited materials or other substances regulated by this Ordinance. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the owner or user's own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the District for review, and shall be approved by the District before construction of the facility. All existing users shall complete such a plan by January I, 1983. No user who commences contribution to the District faci lities after the effective date of this Ordinance shall be permitted to introduce pollutants into the system until accidental discharge procedures have been approved by the District. Review and approval of such plans and operating procedures shall not relieve the industrial user from the responsibility to modify the user's facility as necessary to meet the requirements of this Ordinance. In the case of an accidental discharge, it is the responsibility of the user to immediately telephone and notify the District office of the incident. The notification shall include location of discharge, type of waste, concentration and volume, and corrective actions. I. Written Notice. Within five (5) days following an accidental discharge. the user shall submit to the General Manager a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the District F aci lities, fish ki lis, or any other damages to person or property; nor shall such notification relieve the user of any fines, civil penalties, or other liability which may be imposed by this article or other applicable law. 2. Notice to Employees. A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees of the user whom to call in the event of a -8- dangerous discharge. Employers shall insure that all employees who may cause or suffer such a dangerous discharge to occur are advised of the emergency notification procedure. Section 8-403. Fees. A. Purpose. It is the purpose of this Chapter to provide for the recovery of costs from users of the District's wastewater disposal system for the implementation of the program established herein. The applicable charges or fees shall be set forth in the District's Schedule of Charges and Fees. B. Charges and Fees. The District may adopt charges and fees to compensate the District for its activities which may include: I. Setting up and operating the District's Pretreatment Program; 2.
