370 Other Supplies The 1975 budget figure for this item is $20, 000. We are asking for 20, 000 for 1977. We will make a strong effort to reduce our expenditures in this category. - This is the account for maintenance items to maintain and operate the entire Plant. Some examples of the items procurred under this account are. Grease for pumps & motors, packing for all our various pumps, paint for buildings and machinery, nuts and bolts, pipe fittings; cleaning solvent, welding supplies, gaskets, lumber, etc. 371 Chemicals The 1976 budget figure for this line item is $470, 000. Our request for 1977 is $242, 000. This is a rather sizeable item and, we feel, warrants some discussion. An important part of the recent Plant expansion program were the facilities included to remove Phosphorus from the Plant effluent. The Phosphorus removal facilities were designed to use lime. However, early during the Plant construction phase it became evident that the lime method but quite expensive. As we became aware of the magnitude of the chemical expense facing us, we launched a rather extensive program to investigate Alternate Chemical methods. Our Laboratory people under the early guidance of Ten -Ech Environment Consultants carried out this study. We are currently in the process of changing from the Lime Method to the Ferric Chloride, under the guidance of our Laboratory people. Our budget request for 1977 is based on the success of this change over. If we make this switch successfully it will result in a savings of about $720, 000. This would be possible had we not launched this investigation back in 1971. We tabulate below various combinations of Chemical cost figures and follow this tabulation with some explanations.
