PLAINTIFF'S EXHIBIT A A/C Pipe Producers Association Board of Directors Sf Internal Correspondence FROM June 1984;. News Article on U.S. Environmental Protection Agency (EPA) Research on Lining A/C SUBJECT Pipe Reference: JFW correspondence, U.S. Environmental Protection Agency - Research on Lining A/C Pipe, February 16,1984 ACTION REQUIRED: Review for Information The enclosed article appeared in the June 6, 1984 issue of Toxic Materials News. It describes the report distributed in the above reference. Unfortunately, the title suggests that cement mortar linings are "needed" to control fiber release from A/C pipe. This is not correct. The Agency's Municipal Environmental Research Laboratory also has demonstrated that a number of water treatment/stabilization strategies are effective in preventing fiber release. If you have any questions, please do not hesitate to call. JFW/bwm cc: A. H. Kahn, Esq. copies to: Board of Directors International Affairs Committee L. Ambler F. Layton L. Taylor L. Cejudo J. M.

The EPA Municipal. Environmental-Research Lab in Cincinnati, Ohio, found that cement-* mortar linings are ."useful for .rehabilitating' structurally sound pipe" used by the We3tonr Wis.," Watery Utility.".............. ` [' The other two tested, techniques" -- flushing and using zinc chioride to encapusulate the asbestos-- failed to control fiber contaminationJ EPA said that the zinc phosphide treatment failed due to the presense, of polyphosphates, which are added to water to sequester iron and manganese. Flushing .the pipes actually increased asbestos concentrations because higher water pressures needed to flush the system enhanced fiber, release from old pipes.

CHEMICAL CONTAMINATION" CLOSES SEATTLE'S 'KITE-FLYING MECCA' V\ The kite-flying days may be over for Seattle residents who frequented the city's popular Gas Works Park on Lake Union. Susan Stillman describes the park as "a real kite-flying mecca," but Mayor Charles Royer closed the park to pro tect the public from potential cancer risks after testing revealed that the park's soil contains residues of several carcinogenic substances. Analysis by the U.S. Environmental Protection Agency revealed that the soil in the park contains polynuclear aromatic and polyaromatic hydrocarbon com pounds. Chemical vapors were measured by EPA workers at up to 1,000 parts per million. .The pollution is due to the Seattle Gas Co., which produced gas at the site between 1930 and the mid-1950s. Pollutants are also from a tar company and a benzene-manufacturing plant which operated at the same time. The.park itself was built by filling in a portion of Lake Union with coal waste products. Locals reacted to the closing of the park, opened in 1976, with dismay. "You're kidding ... I think it's a tremendous loss," said Phil Bohn. But after seeing EPA workers in protective suits testing the park, residents are abiding by Mayor Royer's decision to close the park until more information Is available on the risk of using the park. CSMA ASKS HOUSE PANEL TO SUPPORT FOIA PROTECTIONS FOR CBI DATA The Chemical Specialties Manufacturers Assn, is supporting a Senate bill that would impose new restrictions releasing data held by the government through Freedom of Information Act requests when the data contains confidential business information. CSMA President Ralph Engle May 30 urged a House government subcom mittee to adopt S.774, which would give a company an opportunity to challenge an FOIA request for CBI data held by the government. Engle noted that, due to environmental laws like the Toxic Substances Con- trol Act, companies must submit trade secret data to the government even though current FOIA rules do not provide adequate CBI data protections.
