NOW, THEREFORE, BE IT RESOLVED that the following administrative regulations and policies be, and the same are hereby adopted: 1. The following materials shall be excluded from the sewer- age system: a. Gasoline, cleaning solvent, fuel, oil, etc. These are highly inflammable coupounds and serious damage due to explosions of these liquids or their vapors have occurred within sewerage systems. b. Ashes, sand, cinders, rocks, etc. These inorganic compounds add excessive solid loadings ors the sewerage system, causing unnecessary cleaning and maintenance. c. Tar, plastics and other water insoluble vicous materials. These compounds do not break down by bacterial action, and add to the solid loading of a sewerage system. d. Mineral oils, lubricating oils, etc., do not decompose in the normal course of sludge digestion. They cause potential fire hazards throughout the sewerage system, cause excessive cleaning and impose an unnecessary solid loading upon the sludge system. e. Feathers, hair, rags, fibrous paper products, paper towels, etc. These materials cause excessive maintenance throughout the sewerage system. Feathers and hair do not readily digest in sludge digestion processes and create excessive matting on top of the decomposing sludge. f. Metal broken glass, shavings, etc. These materials will readily plug up sewer lines, pumps and appurtenant equipment. g. Unshredded gargage. Large pieces of unshredded garbage cause sewer lines and pumps to clog and excessive mainten- ance will occur. Garbage ground in domestic and industrial grinders to a size of 1/4 inch or less is satisfactory. h. Wastes which contain or result in the production of toxic, corrosive, explosive and malodorous gases. -1- 2. The provisions of the following sections and the values herein set forth shall not be regarded or construed as regulating or limiting the quantity or characteristics of any specific wastes which may be received into the sewerage system but shall serve as a guide in the administration of Section 26.27 and Sections 26.27.1 through 26.27.7 of the Chula Vista City Code, regulating the use of the public sewerage system for the purpose of determining, in general, the acceptability of waste for admission into the sewerage system. In considering the following sewerage characteristics, the dilution effect of the sewerage at the point of discharge or any affected part of the system and whether or not unusual attention or expense would be required to handle such material in the sewerage system shall be taken into consideration. a. The admission into the public sanitary sewers of any water or waste having an average daily flow greater than two (2) percent of the average daily flow at the sewerage treatment plant shall be subject to review. b. Sea water and salt water brines containing more than ten (10) percent salt should be excluded if their dis- charge interferes with the operation of the sewerage system. Large volumes of sea water cause excessive generation of malodorous gases due to the salt content. The salt content is not desirous if fertilizer is pro- duced or water is reclaimed from the sewage into which the discharge is made. Storm drains should receive this water. c. The temperature of industrial waste discharged into the sewerage system should not be above 140° F. d. Industrial wastes having a grease and oil concentra- tion in excess of 200 ppm. will be considered individually. If the sewerage system can safely receive said wastes, industrial wastes having a higher grease and oil concen- tration could be allowed. e. The pH of industrial wastes shall average between 5.5 to 9.0 daily. The maximum variation on a temporary basis during any twenty-four hour period shall not be less than 5.0 or greater than 10.0. f. Industry discharging toxic wastes into the sewerage system will be considered individually. Limitations as to the discharge of water containing toxic substances shall take into account the total amount of such sub- stances which can safely be received at the sewerage treatment plant or at the point of final discharge, whichever is affected. g. Industrial wastes containing radioactive compounds will be considered individually. h. Industrial wastes having a biochemical oxygen demand (BOD) in excess of 400 ppm. will be considered individually. If the sewerage system can safely receive said wastes, wastes having a higher BOD can be allowed. i. Industrial wastes having a of 500 ppm. will be considered age system can safely receive a higher suspended solids can -2- suspended solids in excess individually. If the se~,aer- said wastes, wastes having be allowed. .~.~ j. Where warranted, installation of an appropriate man- hole for purposes of sampling the final industrial waste discharge may be required. 3.
