Ramon Burton July 12, 1985 Page 3 PACE Laboratories, Inc. is currently dealing with several companies in the metal finishing and electro plating industry which are required to instdll pretreala:ent equipment to treat their wastewater streams prior to discharge in the sanitary sewer system. Several of these firms utilize caustic in their treatment process. We are in the process of contacting these firms to determine if sodium hydroxide sludge could be used in their treatment processes. To make this waste exchange concept a reality we also need to discuss the PIPCA requirements for transportation of the sludge to a local industry and the ability of the industry to receive the sludge as a raw product rather than a hazardous wastestream. Packaging of the sodium hydroxide sludge would be necessary if the sludge was sent off site to a hazardous ~aste disposal facility and most probably, if the sludge was sent to another industry in the waste exchange concept. However, the packaging would not be necessary if the sludge were treated on-site by Waltek, Inc. Freon Waste - Our inventory showed a total of 33 55 gallons drums containing freon waste. The majority of these drums were 1/4 to 3/4 full. All drums were closed head 17 E steel drums. Several of these drums would probably require repackaging prior to off-site shipment. Attached to this report is our laboratory analysis of the freon waste. We have also completed a Waste Research and Reclamation Spent Materials Survey form which sl~ould be reviewed, signed and forwarded to Mr. Gene Jameson at Waste Research & Reclamation Company along with a copy of our laboratory report. Itydrofluoric Acid/Nitric Acid Waste - It is our understanding that Waltek, Inc. only generates approximately 1 55 gallon drum of this ~vastestream annually. Approximatly one drum of the waste is currently on-site. Again, the only hazardous property of t~is wastestream is its currositivity (see our attached laboratory report). It is recommended that tl~is wastestream be neutralized on-site and discharged to either the Anoka SaniCary Sewer System or your drain field. Prior to neutralization ~-nd discl~arge, permission wil) have to be obtained from either the City )i' Anoka or tne HPCA ~.~ith respect to discl)arging tills wastewater stream ~o the drain field, or sewer system. IJur report of laboratory analysis is attached for the shell waste, .jrinding residue, and wheelabrator residue. Our analyses have shown these three ~astestreams to be non-hazardous. As such, we have completed ~nd attaci)ed to this report the IqPCA, "Request for Co-Disposal of ~lon-Hazardous Industrial Waste" forms. Tl~ese forms should be reviewd by ',-~altek, Inc. and if acceptable signed. You v~ill also need to obtain the ~i~n.'~tur~ of tl~e sanitary landfill operator ',-~t~ere the waste ~ould be .~ii.~i;,..~l i'o,' di sposal. '.)nce ~:~e'.;t.' ~i.]na tures i~,~ve becel obtained
