SAN FERNANDO VALLEY BASIN(GWQMP-SFVB)

MEETING MINUTESJANUARY 22, 1985

The bimonthly meeting of the Interagency CoordinatingCommittee (ICC) was held at 9:30 a.m. on Tuesday, January 22, 1985,in Room 1571 of the Los Angeles Department of Water and PowerGeneral Office Building. The attendance list and meeting agendaare attached (see Attachments 1 and 2). The minutes of theNovember 20, 1984 meeting were approved without comments.

Tom Gibson (LADWP) presented a slide program describingthe activities and recommendations of the Groundwater QualityStudy of the San Fernando Valley Basin and the status of theimplementation of those recommendations. This program, whichcontains 38 slides, will be made available to member agencies assoon as a standard script is prepared. The slide showing theTCE/PCE levels in the SFVB wells will be updated.

Following this presentation, reports were heard fromeach chairperson of the six ICC subcommittees and have beensummarized below. Minutes of all the ICC subcommittee meetingsare available on request.

Public Education - Miriam Gensemer

A public education work plan is being developed by thePublic Affairs Division (LADWP) with input from the subcommittee.A groundwater quality brochure, which is in draft form, may bedeveloped into one or more brochures depending on the audiencethat the committee chooses to target. John Jacks (CDM) suggestedthat a bilingual program of brochures and handouts would be practi-cal and effective. Discussions within the subcommittee includedmore involvement of other agencies in the hazardous waste educa-tion program.

M. Gensemer (SCAG) reported on the State DOHS workshopon hazardous wastes held on December 13, 1984. The talks dealtprimarily with residential hazardous waste programs in Los Angeles.The Seattle program was particularly promising as a model for theSouthern California area. She said that the same workshop held(in Berkeley drew a larger audience compared to the one inLos Angeles. Jose Ochoa (County DOHS) briefly mentioned the cur-rent hazardous waste collection program in the Riverside/OrangeCounty area. -::

Regulation of Private Disposal Systems - Robert Van Ark

0000186

Robert Van Ark (LA Bur/Eng) reported that no progresshas been made since the last ICC meeting on the ordinance requiringhookup to sewers. R. Van Ark urged the management of the Bureausof Sanitation and Engineering to follow up and encourage thedevelopment of this ordinance. At present the subcommittee's workand ideas about the proposed ordinance is in the City Attorney'sOffice for their use. The Crescenta Valley County Water Districthas reported that over 80% have voluntarily hooked up to the sewersystem. Everyone in that water district should be hooked up byDecember 1985. A large map of the SFVB was presented and used todefine the scope or areas included in the GWQMP-SFVB program.

R. Van Ark reported that he is aware of areas within thescope area that are not represented in the ICC. The Cities ofLa Canada/Flintridge are part of the Verdugo Basin and presently arenot on sewere system. However, M. Blevins (LADWP) pointed out thatparts of these cities are in the Raymond Hill Basin and drainageappears to flow away from the Verdugo Basin. L. McReynolds suggestedthat these cities should be contacted to discuss their situation andinvited to the next ICC meeting.

The KCBS's request for the names of 12 industries thatwere identified as illegal waste disposers was also discussed.KCBS's intention appeared to be targeted at regulatory agenciesto determine why these violators were not fined or cited.

Augmented Enforcement - James King

Jim King (LADWP) reviewed the problems of the enforce-ment penallties for the ordinance to require sewer hookup, thetypes of penalties that should be applied to violators, and thegeneral overview of the ordinance.

J. King also reported on the status of regualtions forunderground storage tanks.

R. Van Ark pointed out that both the areas of sewerhookups and and underground storage tanks are addressed by othersubcommittees and that this subcommittee was duplicating theirefforts. L. McReynolds suggested that the Augmented EnforcementSubcommittee combine with one of the other subcommittees and thendropped from the agenda.

Regulation of Storage tanks, Sumps andPipelines - Johnathan Hall (for William Lebeck)

The committee is still exploring the best possiblemethod of monitoring storage tanks. The committee is in agreementthat monitoring wells should only be used when no other method isfeasible. Various types of monitoring devices were discussed.

- 3 - 0000186

The State regulations on underground storage tanks willinclude broadened guidelines for monitoring requirements, althoughthere appears to be no conflict with local authority/ provided thatlocal authority has passed an ordinance.

The Los Angeles Fire Department (LAFD) has rejected aproposal by the State Fire Marshall's Technical Committee forPipeline Safety to broaden requirements for leak detectionreporting for pipeline failures.

The LAFD has recie_ved the first draft of the MasterInventory List of underground tanks storing hazardous materialsin Los Angeles City and County. J. Hall estimated that there areapproximately 7,000 underground tanks within Los Angeles County.The LAFD is currently trying to define the scope and structure ofits Hazardous Materials Unit,.

Small Quantity Generators Hazardous Waste DisposalProgram - Mai Toy/Miriam GenjTemer

M. Gensemer (SCAG) clarified one point in the slidepresentation made at the beginning of the meeting. The SmallQuantity Hazardous Waste Disposal Program is a single studyconducted by SCAG in cooperation with the Bur/San rather thantwo separate studies.

She reported on the development of a central collectionservice/transfer station that would recieve materials from theNorth Hollywood area. Although it will be quite some time beforethe transfer station is constructed, SCAG will begin with acollection program and an education program for small businesses.Progress to date includes an ;p&M manual for the transfer serviceand a design for the collection service. The annual projectedvolume from the target area is 220,000 gallons.

Siting of the transfer static has been difficultbecause of the desired 2,000-foot buffer zone. SCAG reportsidentifying the potential zones for siting were distributed atthe meeting. The DWP Valley Generating Station was ranked as themost suitable site for the collection and transfer of hazardouswastes. Municipally owned lands were preferred because of thehigh cost of privately owned lands. R. Fabrikant noted thatsince this will be the first municipally owned hazardous wastedisposal site, the level of liability must be clearly defined.

J. Ochoa (County DOHS) asked whether this transferstation would be for commercial use only. M. Gensemer's responsewas that since the household hazardous waste study concluded thatresidential waste was more of a health and safety problem ratherthan a potential groundwaer contamination problem, the use of thetransfer station would be limited to small conunericial generators.

Regulation of Landfills, Groundwater Monitoring andAquifer Management - Mel Blevins

Mel Blevins (LADWP) reported the installation of fourmonitoring wells in the area of the Sheldon-Arleta landfill whichwill be used to determine the effect of spreading at the TujungaSpreading Grounds on the nearby landfill.

Wells are being drilled upgradient and downgradient ofvarious other landfills in the SFVB to monitor the effects oflandfills on groundwater quality.

Three exploratory wells have been drilled downgradientof the Hewitt landfill to evaluate the water quality in the areasproposed for a new LADWP production well field. Data from thesewells will be used to determined if any preventive measures willbe necessary to preserve the groundwater quality in this area,(see Attachment 3).

Aquifer Management

L. McReynolds updated the ICC on the activities of theNorth Hollywood #24 and #5 wells. The results of the well packersindicate that it is an effective means of confining TCE/PCEcontaminated zones (see Attachment 4) .

Other items discussed include the status of Superfundmoney and EPA guidance, the progress of Camp Dresser and McKee(EPA consultants) on their remedial study for the SFVB GroundwaterBasin, and a process for TCE/PCE removal by ultraviolet-ozoneprocess.

Other Business

There were no further items of business to discuss.The meeting adjourned at 11:40 a.m. The next meeting of the ICCwas scheduled for Tuesday, March 19, 1985, at 9:30 a.m. inRoom 1571 of the LADWP General Office Building.
