ITEM: 5

SUBJECT: Executive Officer's Report

DISCUSSION:

Capacity Problems at the Woodbridge Sanitary District, San Joaquin County
The Woodbridge Sanitary District operates a domestic wastewater treatment system in Woodbridge, San Joaquin County. During an annual inspection, Regional Board staff learned the District was planning to revert control of three wastewater ponds to a former owner. On 30 June 2000, the Regional Board required the District to prepare a water balance evaluating the hydraulic capacity of the system with and without the ponds. The water balance was submitted and it showed the treatment system lacked adequate storage capacity without the ponds. The District was required to prepare a Winter Contingency Plan and a Workplan describing the District's approach to meet the capacity requirements for domestic wastewater treatment systems. The Winter Contingency Plan was submitted and approved by Regional Board staff. The District is continuing to prepare the Workplan to address the long term storage requirements. At the request of the District, staff attended the District's 14 February 2001 public meeting to discuss the storage requirements and the importance of completing the capacity improvements by 1 November 2001.

Mountain House Development, San Joaquin County
Mountain House is a new planned community to be built west of Tracy in San Joaquin County. On 29 March 2001, Trimark Communities, developer of Mountain House, submitted 11 Notices of Intent (NOI) to comply with the General Dewatering and Low Threat Discharges NPDES permit for various dewatering projects necessary for construction of the community infrastructure. The NOIs propose to blend ground water containing high concentrations of total dissolved solids with water from Byron Bethany Irrigation District and discharge to the Delta Mendota Canal. Staff must determine if coverage under the General Permit is appropriate or if an individual permit, which would take several months to develop, is necessary. If an individual permit needs to be issued, the delay in construction onset would be costly for Trimark.

Cleanup and Abatement Order, City of Riverbank Wastewater Treatment Plant, Stanislaus County
On 5 March 2001, the City of Riverbank reported that freeboard in all ponds at the City's Wastewater Treatment Plant was significantly less than required, and that it was in danger of spilling wastewater. Because of this current problem, as well as a levee failure last summer that released over 20 million gallons of treated effluent and a subsequent engineer's report questioning the stability of the levees, the Executive Officer issued a Cleanup and Abatement Order requiring the Discharger to develop and implement a Contingency Plan to prevent a release and long-term measures to improve the levees, improve percolation capacity, and reduce winter inflow and infiltration.

CL Complaint, Calfed Bank, Amador County
On 9 January 2001, the Exectuve Officer issued Administrative Civil Liability (ACL) Complaint No. 5-01-501 to Calfed Bank for $5,000. The Bank acquired land near Ione in Amador County when it acquired Glendale Savings Bank. A mining company had previously conducted exploratory mining activities and created a mine tailings pile. Wastes discharged from the tailings to surface waters. The Bank prepared a work plan for cleaning up the tailings but failed to submit a report of waste discharge to obtain an NPDES permit in violation of Water Code section 13376 and 13385. The Board received one comment letter objecting to the amount of and legal basis for the ACL. The Executive Officer determined that, based on the factors required to be considered in Water Code section 13385(e), the amount of and legal basis for the ACL was sufficient.

Submittal of $10,000 ACL Payment, Hatler Industrial Park, Tuolumne County
On 16 June 2000, the Board issued Administrative Civil Liability (ACL) Order No. 5-00-167 to Sidney H. Hatler, Stewart E. Hatler, Vernon P. Hatler, and Richard D. Young (Hatler) for failure to submit a completed Report of Waste Discharge. Hatler petitioned the ACL to the State Board on 17 July 2000. On 25 August 2000, the State Board dismissed the petition because the petitioner failed to raise substantial issues appropriate to justify a review of the case. Staff forwarded a notice to Hatler on 14 September 2000 ordering payment of the fine by 25 September 2000. After Discharger's failure to submit payment in a timely manner, staff asked the Sacramento County Superior Court to enter a Judgment to Collect. Staff then served the Judgment to the Discharger, and the full $10,000 payment was received on 17 March 2001.

Multiple Wastewater Spills, Groveland Community Services District, Tuolumne County
Within the past year, the Discharger has reported six spills of raw sewage from their collection system and one spill of secondary treated disinfected effluent from their reclamation system to surface water drainages. The estimated total volume of the raw sewage spills was over 20,000 gallons and the estimated volume of the treated effluent spill was over 35,000 gallons. The spills were all to watercourses that are tributaries of Pine Mountain Lake, and were the result of insufficient monitoring and/or maintenance of the collection and reclamation system. Staff has received complaints from three members of the local community, one of whom requested that the Board impose a connection ban. Staff is in the process of preparing an enforcement action. (JRM)

Submittal of $8,864 ACLC payment, Amador County Public Works Department
On 13 October 2000, the Executive Officer issued a $30,000 ACLC to Amador County for spills of approximately 81,000 gallons of wastewater from several of its lift stations. After meeting with the County, the Executive Officer agreed to settle the ACLC for the actual cost savings incurred by the County from not installing adequate safeguard or warning devices at the lift stations. On 25 January 2001, the County submitted a payment of $8,864 to settle the ACLC. (WSW)

Failed Leachfield at Safari Mobile Home Park, Calaveras County
The domestic wastewater from Safari Mobile Home Park is discharged to a leachfield adjacent to the Avery Middle School. The leachfield property is unfenced area and accessible to the public. For the past 15 years, staff of both the Regional Board and the Calaveras County Environmental Health Department have conducted inspections of the leachfield. Numerous samples have been taken, and the analytical data confirms that effluent is surfacing from the leachfield and running down a roadside ditch.

In 1989, the Board issued a Cleanup and Abatement Order to Safari Mobile Home Park, requiring the owner to employ whatever means were necessary to prevent the surfacing of wastewater. Subsequent inspections indicated that adequate measures had not been taken. Therefore, the Regional Board adopted a Cease and Desist Order in 1995, which again ordered the owner of the park to either cease discharge to the leachfield or employ whatever necessary to prevent surfacing of sewage. Subsequent inspections have shown that the Discharger is violating the C&D. In January 2000, the Discharger and Calaveras County Water District (CCWD) reached an agreement to connect the park up to the CCWD sewer system. However, as of March 2001, the mobile home park has not yet been connected, and effluent continues to surface from the leachfield. On 13 March 2001, the Executive Officer requested that the Discharger submit a RWD pursuant to Water Code Section 13267. Staff will evaluate this information and propose appropriate enforcement actions. (JSK)

Staff Investigates Gray Water Discharges from Shasta Lake Houseboats, Shasta County
Shasta Lake is part of the Whiskeytown-Shasta-Trinity National Recreation Area (NRA) established by Congress in 1965. One goal of the NRA is to provide public recreation including boating. The U.S. Department of Agriculture, Forest Service administers the NRA and has established a permitting system to limit the number of houseboats on Shasta Lake to 450 commercial and 648 private vessels. The Basin Plan currently prohibits the discharge of toilet wastes from houseboats to Shasta Lake, but not gray water. Houseboats may be equipped with hot tubs; showers; kitchen, bathroom, and wet bar sinks; dishwashers; and washing machines. The Harbors and Navigation Code describes wastewater from these drains as gray water.

Within the Central Valley Region, staff has determined that gray water is retained on houseboats operating on many inland surface water bodies including Lake Oroville which has a capacity of 3.5 million acre feet. However, on Shasta Lake, the Forest Service has permitted gray water discharges contending that the dilution of the waste in the 4.5 million acre foot reservoir precludes serious threats to public health. Houseboat gray water is uncontrolled; therefore discharges may occur adjacent to marina docks, swimming areas, and may enter a houseboat's non-potable water supply for use in showers and sinks. Shasta Lake is also a source for drinking water for several of the resorts and surrounding communities. A June 1998 Gray Water Technical Paper prepared by DHS reported that household gray water has characteristics similar to raw sewage. This summer, staff will continue to investigate the characteristics of houseboat gray water and the potential impacts these discharges have on the beneficial uses of Shasta Lake. Staff intends to bring this issue to the Board at the September meeting. (KLC)

Trichloroethene near Dudley and Petty Site, Corning, Tehama County
Trichloroethene (TCE) has been detected in several domestic wells east of the former Dudley and Petty Truck Stop site in south Corning. This site caused extensive diesel fuel contamination in ground water, but the source of TCE is currently unknown. Dudley and Petty declared Chapter 7 bankruptcy in 1991. Therefore $627,000 has been allocated to the City of Corning from the Cleanup and Abatement Account for site investigation and cleanup. Also $40,000 has been allocated to the Regional Board to supply wellhead filtration to nearby residences with wells contaminated with TCE. If the source of the TCE is found, investigation and cleanup costs will likely exceed allocated funds. Currently Regional and State Board staff are working with the City of Corning in drafting an invitation to bid for the City to investigate TCE sources. Results of this focused work scope may be used to request assistance from the Department of Toxic Substances Control or the U.S. EPA in removing the contamination from groundwater. (EJR)

Dry Cleaner Closed
TEAM Enterprises, Inc., owns a former dry cleaning facility in Madera. TEAM provided technical reports detailing recent hydrogeologic investigations at the site. TEAM reported PCE has not been used and/or stored at the subject site for over 10 years. Initial passive soil gas surveys indicated the presence of PCE. TEAM sampled its pipes in the building and found no detectable PCE. Analytical results for soil samples found no detectable PCE in samples collected from 1, 5, and 10 feet below ground surface in eight Geoprobe borings. After evaluating the provided information, a no further action letter was issued to TEAM Enterprises, Inc. (AM)

Pipeline Spill to Aqueduct
In 1987, a pipeline owned by Unocal adjacent to the California Aqueduct was discovered to have released crude oil to soils directly adjacent to the Aqueduct. In 1997, a failure in the Aqueduct's concrete panels occurred in the area of the contaminated soil resulting in the release of crude oil into the Aqueduct. Changes in ownership (Unocal to Tosco) of the pipeline have resulted in slow progress being made with respect to remediating the contaminated soil and groundwater. Staff held a meeting with both TOSCO and DWR aimed at developing a reasonable remediation plan and timeline for completing the work in this sensitive location. Staff is closely monitoring progress with the agreed-upon action plan. (AM)

Pond Closure/Dairy Project Continues
Fresno staff continues to work with dairyman Rob Hilarides regarding completion of construction of a clay cap system designed to address closure of one set of former olive brine wastewater disposal ponds purchased from the City of Lindsay. He is proposing to construct a 10,000 cow dairy operation on top of the closed pond site. Mr. Hilarides, along with several other proponents, are currently involved in preparation of an EIR regarding several dairy projects proposed in Tulare County. (SRG)

Illegal Oilfield Discharges
Fresno staff is working closely with the California Department of Oil, Gas, and Geothermal Resources in pursuing an increased number of complaints of unpermitted discharges of wastewater, some containing crude oil, to land and ephemeral streams in Kern County. The ephemeral streams are considered Waters of the U.S. and the unpermitted discharges are in violation of the federal CWA. Increased oil prices appear to have led to increased production resulting in upsets and overflows by several operators including Crimson Resources, Bracken Oil, Oakland Petroleum, Nuevo Energy, and Hank Hall. (SRG)

Brine Disposal Sites
Fresno staff is actively pursuing site characterization at three small former olive curing facilities in Tulare County and an animal rendering/hide curing facility in Kings County that have or had highly saline wastewater discharges to unlined ponds. Initial results indicate that they have all impacted groundwater. (SRG)

Headway Being Made In Reducing Landfill WDR Backlog
Fresno staff are making headway in reducing the backlog of old landfill WDRs. At the beginning of the fiscal year, there were 11 backlogged WDRs for landfills in the southern valley. Four WDR updates have been approved by the Board, and two are on the April agenda. Four of the remaining five are tentatively scheduled for the June Board meeting. Draft WDRs for the Bakersfield Metropolitan (Bena) Landfill, are complete except for reflecting a demonstration by the Discharger that its proposed liner design will meet the performance standard for containment structures required by Title 27. If the demonstration is submitted in time, the Bena WDRs will also be submitted for the June Board meeting. (REH)

Gasoline Release at Oakhurst Shell Impacts Offsite Water Supply Wells, Madera County
Oakhurst Shell replaced two 10,000-gallon gasoline USTs in 1997. MTBE has been as high as 490,000 g/l and TPHg as high as 250,000 g/l in the shallow aquifer. Last December 23 wells within 1,200 feet of the site were sampled. These wells top the deep fractured bedrock aquifer in the area and five contained MTBE. Two of the wells contain MTBE just below the MCL of 13 g/l. Remediation of the shallow soil should commence within 6 months. Investigation of the deep aquifer should commence within 8 weeks with remediation commencing within 8 months following the investigation.

El Dorado Mobile Home Park Spills Wastewater, Kings County
On 13 February, power and equipment failures due to a rainstorm resulted in the discharge of approximately 5,000 gallons of untreated wastewater from the WWTF to an emergency storage pond. The Discharger restored power and repaired equipment within eight hours of the initial failure. The Discharger disinfected the effluent in the emergency pond by hand broadcasting calcium hypochlorite onto affected areas. Board staff anticipates no further action. (ARP)

Lamont Public Utilities District Has Multiple Spills, Kern County
On 26 February, the Lamont WWTF collection system overflowed at a manhole because of a grease blockage in a sewer line. The line was cleared and the area disinfected with sodium hypochlorite and washed back into the manhole. On 21 and 22 February and 19 March the WWTF spilled 2,000 gallons, 4,000 gallons and 1,000 gallons, respectively due to operation and maintenance errors. No wastewater left the WWTF area. The spills resulted from valves being left open and poor operations during WWTF modifications. The District has committed to establishing protocols requiring increased observation of effluent discharge rates and will train operators accordingly. Staff is considering appropriate informal enforcement. (ARP)

Franklin County Water District Lacks Disposal Capacity, Merced County
On 6 February, the District submitted a letter indicating that the existing disposal ponds are at capacity and additional disposal area is needed to accommodate discharge flows for the remainder of the year. The District proposed to use a newly acquired area for an interim disposal pond. A Board letter requires the District to submit specific information about the proposed discharges and how it intends to resolve capacity problems. (ARP)

SK Foods Threatens to Begin Fourth Processing Season In Violation, Kings County
WDRs govern SK Foods discharge of tomato processing wastewater to 160 acres of property owned by the City of Lemoore, and to the Westlake Canal. The Discharger has chronically violated the WDRs, including threatening to effect the beneficial uses of Westlake Canal, a warm water fishery and a water of the State. Staff issued a conditional waiver for land disposal at an alternate location during the 2000 processing season. Unfortunately, conditions were not met and nuisance conditions developed. SK Foods has proposed a similar method of disposal at still another site for the 2001 processing season. As happened last year, the disposal proposal when submitted will not allow sufficient time for staff to process the requirements prior to the 2001 processing season. Staff is drafting a CDO to be considered by the Board. (JDR)

Groundwater Pollution in the City of Reedley, Fresno County
Groundwater data submitted by the City of Reedley indicates groundwater in and around the WWTF is exceeding MCLs for nitrates and ECs. The City has not yet fully characterized the horizontal and vertical extent of groundwater pollution underlying the WWTF. (JDR)

Sewer-line Cleanings and Video Inspections Scheduled Within Yosemite Valley
The NPS will conduct sewer-line cleanings and video inspections of approximately 15 miles of sewer lines and manholes within Yosemite Valley. In accordance with a CAO, the NPS submitted all documents required for the March 2001 project. The documents describe the plans and procedures that will be completed during the project to prevent and, if necessary, clean up resulting sewerage spills. (JDR)

City of Lemoore Requests Canals Not Be Designated As Warm Water Fisheries
The City of Lemoore recently requested that Blakely and Westlake Canals not be considered "Waters of the State" and designated as warm water fisheries. The Discharger's request is based on the fact that the canals are on, and the water is utilized on and drains to, Westlake Farms property. The City has seasonally caused violations of minimum dissolved oxygen limits and caused a fish kill, so removing designation would be advantageous to it. (JDR)

City of Lindsay Addresses Illegal Dairy Discharge, Tulare County
Lindsay discharges 0.45 mgd of citrus wastewater to land for reclamation and leases it for farming of alfalfa. Pressure problems associated with the discharge of the wastewater resulted in the City finding two pipelines running from an adjacent dairy to the land. The City severed the lines along with their relations with the farmer who allegedly plumbed the discharge from the dairy. Neither the nutrient nor hydraulic loading of the dairy is addressed in WDRs and may have contributed to on-site soil and groundwater degradation. Staff is considering appropriate enforcement actions. (JDR)

City of Lindsay Experiences Sewage Spill Due To Brown-Out, Tulare County
On 19 March Lindsay experienced a Southern California Edison rolling "black-out." During the event, the main trunk line filled and then spilled approximately 1,000 to 1,500 gallons into the emergency overflow pond. When power was restored, the City drained the spilled wastewater back into the headworks for treatment. The WWTF is currently under construction and does not have a back-up power source on-line. (JDR)

E&J Gallo's Fresno Winery Caused Groundwater Pollution, Fresno County
E&J Gallo monitors groundwater in seven wells throughout its Fresno Winery's 1.5-square-mile waste application area. Past application of ion exchange rinse water polluted groundwater with total dissolved solids and sulfate. Stillage disposal and pomace composting operations may also have contributed to groundwater pollution for nitrates. E&J Gallo's monitoring well network does not adequately monitor groundwater. Last fall, after stillage and composting operations created nuisance conditions of odor and flies, E&J Gallo corrected the problems and hired a UC Davis researcher to investigate stillage treatment options. A work plan for installing additional monitoring wells has been requested. (DAS)

Frito-Lay's Vadose Zone Monitoring Reveals Pollution Potential, Kern County
Frito-Lay operates a snack food manufacturing facility that discharges up to 1.3 mgd of food-processing waste to 330 acres planted in fodder crops. WDRs require monitoring of vadose zone water quality in lieu of groundwater, based on predicted waste management. Nitrogen loadings range from 200 to almost 500 lbs/acre/year. In 2000, lysimeter data from five fields showed vadose nitrate-nitrogen concentrations ranging from 12 to 98 mg/L for waste application fields and less than 0.1 mg/L for a control field that had not received waste. Frito-Lay's 2000 Annual Report predicted nitrate-nitrogen concentrations in percolate would range from 0 to 10.9 mg/L. The vadose zone data indicates that the model did not predict actual field conditions and revised Frito-Lay's monitoring and reporting program to include groundwater monitoring. (JRL)

Dischargers Oppose Implementation of the State Board Biosolids General Order
The State Board recently adopted a General Order for land application of biosolids. Biosolids dischargers regulated by the Central Valley Region's 1995 General Order (95-140) and by site-specific orders were asked to submit NOIs to apply for coverage under the State Board Order. The dischargers were notified of the Board's obligation to rescind Order No. 95-140. Most dischargers with site-specific orders oppose having those orders rescinded and being regulated by the State Board General Order. The dischargers' concerns include increased fees and paperwork, and an impending court decision that may overturn the State Board Order, thus leaving the dischargers without a permit. Staff's goal is to have all sites that apply biosolids operate in accordance with current standards and policies of the Board, whether under the State Board General Order or existing site-specific orders. (JRL)

USA Petroleum on Verge of Satisfying Enforcement Order , Fresno County
A UST site at 5968 E. Kings Canyon Road, Fresno, has been under a cleanup and abatement order for nearly a decade. Vapor extraction destroyed 217,000 pounds of hydrocarbons. Results of groundwater monitoring and sampling events establish that the contaminant plume has been decreasing. After the final confirmation round now pending, the case will likely be closed and the order rescinded. (DAM)

Chevron Resumes Cleanup, Fresno County
A former UST site of Chevron's at 1160 Fresno St., Fresno, has been under investigation for over a decade for significant pollution from a gasoline fuel leak. Chevron ceased remediation in July 1996, as it believed the remediation system was entraining an offsite, non-Chevron gasoline source. The Chevron position cannot be supported technically and last December we directed Chevron to continue groundwater monitoring, provide a workplan to further evaluate the release to groundwater, and provide a work plan to conduct further soil remediation activities at the site. Chevron continues to monitor the groundwater and recently submitted the requested work plan to evaluate the site for further soil remediation activities. (DAM)

Proposed Animal Waste Regulations
US EPA is proposing to revise the NPDES permit regulations and the effluent limitations guidelines for animal feeding operations (AFOs). On December 15, Administrator Browner signed the proposed revisions and started a 120-day public comment period. March 26th, US EPA extended the public comment period to 30 July. US EPA has held public meetings throughout the country to present the proposed regulations. Staff has attended and observed that most commenters do not believe the proposed regulations are practical for application at AFOs.

Staff is preparing comments on the proposed regulations. These comments will be provided to the State Board for submission to US EPA on behalf of the state and regional boards. The comments as currently written indicate that staff does not believe that the proposed regulations can be effectively implemented because they do not adequately protect groundwater, fail to address many discharges of animal wastes to surface water, and impose record keeping requirements that will divert staff resources away from inspection and enforcement activities. (JLM, DWW)

Animal Disease Potential Increases
As a result of the recent concern for Hoof and Mouth Disease in cattle in other parts of the world, Board staff is looking at what we must do to minimize the spread of the Disease should it reach California. Staff will participate in CAL EPA's Emergency Response Multi-Agency Coordinating Group (ERMAC) to develop a response plan to address environmental and public health concerns that will arise should Hoof and Mouth be detected in animals in California. Staff from the Confined Animal Facility Regulatory Unit attended a workshop by the U C Cooperative Extension on biosecurity concerning BSE (mad cow disease) and Hoof and Mouth Disease in Fresno on 12 April. Staff is also collaborating with the California Department of Food and Agriculture (CDFA) to establish a set of procedures that should be followed when conducting inspections of confined animal facilities. In addition, CDFA will conduct training for representatives from several organizations who will then train staff at their respective organizations. Paul Sousa of our Sacramento office will attend and then provide training for other Regional Board staff. (DWW)

San Joaquin River In-season Monitoring for Pesticides
As part of San Joaquin River In-Season Monitoring Plan, staff and students from the San Joaquin TMDL Unit will conduct monitoring of OP pesticides in San Joaquin River Watershed starting April 11, 2001. This monitoring plan includes sampling of 12 tributaries during the irrigation season, April to August 2001. All samples will be analyzed by enzyme-linked immunosorbant assay (ELISA) and will be confirmed using a gas chromatograph/ mass spectroscopy. (SAG, ELR)

Update on the San Joaquin River Salinity and Boron TMDL
Staff is developing a technical Total Maximum Daily Load (TMDL) for Salinity and Boron in the Lower San Joaquin River. Staff has completed an administrative draft Problem Statement and Numeric Target Analysis and is currently developing the Source Analysis, Loading Capacity, and Load Allocation components of the TMDL. The technical TMDL, which includes all of the above-mentioned components, is due to be submitted to the USEPA by June of 2001. Staff will be holding a public workshop in May to present information on the Lower San Joaquin River Salinity and Boron TMDL. The workshop will be a follow up to a previous workshop held on March 1st and is intended to disseminate information to the public and to provide an opportunity for additional public input to the TMDL development process. The workshop will address some of the comments received during the last workshop and will also include detailed discussions of the TMDL Source Analysis and Load Allocations being developed. (EIO)

Update on the San Joaquin River Selenium TMDL
Staff is developing a technical Total Maximum Daily Load (TMDL) for Selenium in the Lower San Joaquin River. Staff has completed a draft TMDL Report that is undergoing internal review. The implementation component of this TMDL has already been incorporated into the Regional Board's Basin Plan through the Basin Plan Amendment for the Control of Agricultural Subsurface Drainage in 1996 and the issuance of Waste Discharge Requirements (WDRs) for the Grassland Bypass Project. These WDRs are scheduled for updated in July. Load allocations in this TMDL will be incorporated into these WDR. Staff will be holding a public workshop in May to present information on this TMDL. (MJM, LFG)

Dissolved Oxygen TMDL
Staff briefed the San Joaquin River Dissolved Oxygen Steering Committee on the required elements for an implementation plan on 21 March. The Dissolved Oxygen Committee has been working to develop the information needed by the Regional Board for a technical TMDL. The load limits and control measures identified in this technical TMDL will be incorporated into the Regional Board's Basin Plan so all the elements of an implementation plan must be identified. (LFG, CGF)

'Beyond the Drain' Conference Held
On 27 March, several staff attended the 'Beyond the Drain' conference that was sponsored by the Department of Water Resources, San Francisco Estuary Project, U.S. Bureau of Reclamation, U.S. Environmental Protection Agency, and the Water Education Foundation. The purpose of the conference was to review the efforts that have been undertaken to improve the management of agricultural drainage in the San Joaquin Valley, with an emphasis on in-valley solutions. Speakers and panels represented numerous state, federal and local agencies. Farmers, consultants, scientists, planners, agency representatives, elected officials, and the general public, attended the conference. Les Grober provided an update on the current status of efforts to manage salt and boron from agricultural drainage. Dennis Westcot served on a panel discussion and answered questions regarding future drainage management. (DWW, LFG)

Proposed Ranking of Prop 13 Proposals
Over 350 proposals were submitted to the State Board to be considered for funding under two Prop 13 sub-accounts: Nonpoint Source Pollution (NPSP) Control and Watershed Protection. Fifty-nine of those proposals were for projects within the Central Valley. On 28 and 29 March, staff participated in the statewide ranking process for proposals submitted under the two sub-accounts. The process resulted in two lists of projects recommended for funding that will be considered for adoption by the State Board during May. Those lists include seven projects in Region 5: four watershed protection projects ($568,000 of the $9.2-million available) and three NPSP Control projects ($1.6-million of the $9.7-million available). A second Prop 13 Request For Proposals will be released in May and it is anticipated that the amount of statewide funding available in each sub-account will double. (JEC)

Increased Monitoring in the San Joaquin River Basin
Since October, staff has expanded its surface water monitoring efforts in the San Joaquin River Basin. Increases include analyses of general minerals, trace elements, nutrients, toxicity, and pesticides in the San Joaquin River and in tributaries representing discharges from major watersheds on both the east and west sides of the basin. The expanded monitoring is in response to additional funding provided by the statewide Surface Water Ambient Monitoring Program (SWAMP) and is conducted at a monthly minimum with increases during storm events and the irrigation season. Also included in the monitoring effort is baseline water quality data collected in the Mountain House Creek watershed (rural ag land slated for development of a city of 55,000 within two years) and bioassessment and habitat assessment in selected water bodies. Monitoring locations and constituents to be analyzed are being coordinated with state, federal and local agency efforts to eliminate duplication and increase the effectiveness of the program. (JEC)

OP Pesticide Focus Group Update
The Organophosphate (OP) Pesticide Focus Group is a working group of the Sacramento River Watershed Program (SRWP) that has been meeting monthly since June 1999 to address the OP pesticide problems in the Sacramento River Watershed. Specifically, the group is focusing on creating a management strategy for diazinon in the Sacramento and Feather Rivers in order to provide some of the technical information needed for the development of Total Maximum Daily Loads (TMDLs) required for the rivers. It is anticipated that the management plan developed will have implications extending to other organophosphates and watersheds. The Focus Group has completed a diazinon loading study, a diazinon targets report, and a report on management practices that may reduce diazinon loading to the Watershed. The Focus Group has completed a draft management strategy that will be distributed for peer review on April 15th and will be finalized in July 2001. (MRM)

SRWP OP Pesticide Focus Group Outreach Projects
The Sacramento River Watershed Program's (SRWP) Organophosphate (OP) Pesticide Focus Group has funded two outreach projects. The first project consisted of 19 presentations given to over 1,500 Agricultural Commissioners, growers, and pest control advisors (PCAs) in the Sacramento River Watershed. The talks provided information on the Sacramento River Watershed, the SRWP, pesticide issues in the Sacramento River Watershed, regulatory issues, the OP Pesticide Focus Group, and potential management measures to reduce OP pesticides in surface waters. The presentations have been completed and a final report is being prepared.

The second outreach project focused on Pest Control Advisors and Nontraditional Outreach. The project focuses on identifying grower groups who are not reached through traditional outreach efforts and conducting small meetings with representative landowners of those groups. The meetings provide information on the SRWP, OP pesticide issues, the current level of adoption of management measures that reduce OP pesticide runoff, and new pesticide management measures that could potentially be adopted by those communities. This project also targets 15 PCA's in the Sacramento River watershed for one-on-one meetings to complete a survey identifying barriers to changing management practices to reduce OP pesticide runoff, responsiveness of their clients to change and awareness of water quality and pesticide issues, and actions to improve water quality. A final report on the success of the project will be available in June. (MRM)

SRWP OP Pesticide Focus Group Implementation Projects
The California Dried Plum Board has been awarded a Clean Water Act 319 grant to establish orchard demonstration sites in the Sacramento River Watershed. The project will be coordinated through the OP Pesticide Focus Group and will establish demonstration sites in dried plum and peach orchards in Butte County starting in the fall of 2001. Effectiveness of the practices in reducing OP pesticide runoff, and consequent effects on aquatic life beneficial uses, will be concurrently evaluated in companion chemical and biological monitoring projects. The project is intended to implement the Sacramento River Watershed Program (SRWP) management strategy in the watershed and to determine the best methods of mitigating OP pesticide runoff from agriculture. A variety of other pesticide reduction programs are currently underway. A goal of this project is to serve as a focal point for coordinating and increasing the efficiency of these other efforts relative to pesticide runoff in the Sacramento River Watershed.

This past fall, bioassessment samples were collected at sites within the project area and will continue to be collected twice a year (fall and spring) for the duration of the project. Chemical monitoring was conducted and flow measurements taken this past winter to collect preliminary information on the sub-watershed before the start of the project this fall. (KB)

West side Sacramento Valley NPDES Dischargers Ceriodaphnia Toxicity Study
Several NPDES permit holders located on the west side of the Sacramento Valley have observed Ceriodaphnia chronic toxicity (low reproduction) during routine whole effluent toxicity (WET) testing. Because these wastewater treatment plants all use groundwater as their supply source, Regional Board staff surmised that the cause of the Ceriodaphnia chronic toxicity might be common among them. Thus, in January 1998 the Regional Board, Sierra Foothill Laboratory (SFL), UC Davis, and a group of west side dischargers initiated a collaborative study to determine the cause. The dischargers participating in the study include the City of Williams, Yolo County Integrated Waste Management, the City of Woodland, the UC Davis Wastewater Treatment Plant, and the City of Davis.

Preliminary results (first 8 months) indicated that the cause of the Ceriodaphnia chronic toxicity was not common among the participating dischargers. Additional studies are underway to identify the individual causes.

Chronic Ceriodaphnia toxicity was observed most often in the City of Williams and Yolo County effluents. Filtering the sample alleviated the toxicity observed in the City of Williams effluent. In addition, studies comparing the pre and post-chlorination/de-chlorination indicated that the toxicant might be a disinfection by-product. Further investigation implicated low-level total cyanide as the toxicant. The disinfection process produces cyanide when the effluent contains organic nitrogen. Future studies on the City of Williams effluent will include nitrification/de-nitrification prior to disinfection.
Toxicity in the Yolo County effluent did not persist long enough for follow-up studies to successfully identify a cause. Future study will need to be designed specifically for Yolo County.

In general, few incidents of Ceriodaphnia chronic toxicity were detected in the UC Davis, City of Davis, and City of Woodland effluents. In addition, since this study began, UC Davis built a new wastewater treatment plant and the City of Davis plant was upgraded to secondary treatment. Consequently, further investigation on these effluents is not necessary. (KLL)

Clean Water Act Section 303(d) List Update
In 1998, the Regional Board adopted a Clean Water Act Section 303(d) list of impaired surface waters, which identifies over 150 waterbody/pollutant combinations. The State Water Resources Control Board has begun the process to update the 303(d) list for California. The Regional Boards are being asked to solicit information and data from the public on the status of each Region's surface water bodies. Regional Board staff will evaluate the information and the Regional Board will provide recommended changes to the 303(d) list to the State Board. The time period for solicitation of information will end on May 15, 2001. Regional Board staff held 303(d) list update workshops in Fresno and Sacramento in March. Two members of the public participated in the Fresno workshop and 8 people participated in the Sacramento workshop. A third workshop will be held in Redding on April 6. It is anticipated that the staff report with recommended changes to the 303(d) list will be available for public review in August and the Regional Board will consider changes to the 303(d) list at the January 2002 Board meeting.
