41. The property or business owner shall submit to the Fir..e Chief calculations which show the concentration of the worst-case spill from the most toxic and/or hazardous material released at the point of discharge to the atmosphere. The discharge calculation shall show the percentage of the "Immediately Dangerous to Life and Health (IDLH) concen- tration limit that is being released, to show the maximum exposure level that could possi- bly be discharged from this facility. If this level is unacceptable in terms of risk to the public's health and safety, a scrubber for the ventilation system shall be installed, subject to the review and approval of the Fire Chief and Director of Building Inspection. 42. All hazardous materials including solids, liquids, and gases, in either the pure, processed, or waste state, shall be used and stored inside the building covered by this development plan approval. 43. NFPA placards indicating the relative hazard of the facility shall be posted at all times at the entrances to this building. The placards shall be posted in a location that is clearly visible by firefighters. 44. The property owner agrees to adhere to the stipulation that there be "no-voluntary- release" of hazardous wastes into the atmosphere or sanitary sewer, and accepts the fol- lowing terms: a. Fume hoods shall not be used for the routine evaporation of volatile materials. b. Waste containing toxic chemicals, as determined by the City, shall not be disposed of in the sanitary sewer system. c. When engaged in dishwashing or equipment cleaning activities when there is reason to believe that contamination with toxic or radioactive substances has occurred, pre- washing of the dishes or equipment to remove substantially all of the toxic or radio- active material, and the disposal of this waste stream as toxic waste, shall be carried out. d. The disposal of any radioactive materials in the sanitary sewer system shall be avoided. Any radioactive material which is disposed in the sanitary sewer system shall not result in any measurable increase in radioactivity in the wastewater stream. The City recommends that the material be stored for a period equal to or greater than 20 half-lives, to assure that less than one-millionth of the original quantity of radioactivity is present. When long-lived isotopes, e.g., 3 H, ~4C, etc., are present in waste-water, no drain disposal is allowed. All radioactive materials must be dis- posed of by a licensed, reputable firm specializing in such operations. No releases of radioactive materials shall take place into the atmosphere.
