However, sewer construction fnnds have not yet been transferred to the above acconnts to cover additional construction costs and District 1aror costs. The additional construction costs were incurred as a result of nnfores2eab1e circumstances (please refer to the attached Position Paper VI OB 1, dated November 1, 1979).

DOLAN General Manager-Chief Engineer DATE May 8, 1980 SUBJECT AUTHORIZATION OF $1,252 FOR THE PURCHASE OF A PORTABLE COMBINATION COMBUSTIBLE, TOXIC GAS AND OXYGEN DEFICIENCY ALARM METER, AND ONE MSA H2S SUPERSIZE GAS MASK TYPE OF ACTION Equipment Request D. G. Niles INITIATING DEPT./DIV. Plant Operations Department SUBMITTED BY Issue: A need has developed for a safety meter for measuring TLV in PPM of H2S concentration, and an appropriate respirator to be used with this meter. Background: In the Solids Conditioning Building and other areas in the plant which are not oxygen deficient, we occasionally have a low-level concentration of H2S from the drain systems. Currently we have no accurate method of determining the concen- tration levels of H2S. The Dynamation Combo 33 unit will afford a reliable method of H2Sconcentration measurement and employee protection from this gas. Recommendation: Authorization of $1,252 for the purchase of a portable combination combustible, toxic gas oxygen deficiency alarm meter, and one MSA H2S supersize gas mask. \ REVIEWED AND RECOMMENDED FOR BOARD ACTION ENG. e~ DGN ."" .:;~,. ,- I",,',",.',' (.!~. c~s: f ~ oa-:. ,', , t,. tbuiJet:: ....

'" ~ G""t N E-rt A L : The COMBO will continuously protect workers in t11'1derground or enclosed areas against combusti- ble, toxic. or oxygen deficient atmospheres. Small and light enough to be worn on the belt, the COMBO can travel with the worker and warn of pockets of gas that might be missed by aspiration testing at the e..ntrance. Attention getting alarm tones and colored indicator lights both warn and distinguish between combustible, toxic, or oxygen deficient conditions. A twin solid state catalytic sensor system detects combustible and toxic gases. It needs no compen- sation for temperature, humidity, or electronic changes. Both combustible and toxic gases are detected continuously. Because of the stability of the twin sensor system, a meter is not required for normal alarm operation or calibration. The inex- pensive sensors last up to 3 years in normal use and plug into the unit for replacement. A chemical electrolytic cell with temperature compensation measures 02 levels. and has up to one year or life before replacement. If needed, this cell may be easily calibrated with the test switch, 02 light, and an internal adjustment. 'The cell is easily changed as it plugs into the circuit board. Because of the unit's unique design, the 02 cell will operate at temperatures as low as 00 F. DESCRIPTION: The COM BOelectronics are all solid state and packaged in a high impact plastic case. The case ;s opened with a release latch on the bottom and hinged on the top. A rubber gasket seals the case at the parting line. The rechargable battery pack C3;1 be changed by opening the case, and replacing the discharged pack with a new one. A porous plastic screen in the sensors' compartment lets the air through, but not water or dirt. The only controls are an ON switch and TEST switch. Three LEO (light emitting diode) alarm lights indicate the type of gas present; red - combustible; yellow - 02 deficient; orange - toxic. A green LEO acts as a pilot light and battery charge indicator. If the batteries need recharging, the green light shuts off and the alarm horn sounds. The instrument may be operated continuously when plugged into the battery charger. OPERATION: The ON switch is moved to,the operate position and the green LED illuminates. The unit requires a few minutes for the combustible and toxic sensors to warm up. During this time the combustible and toxic alarm lights flash without the audio alarm sounding. The horn and 02 cell's calibration may Se checl<ed by depressing the test switch. When .. . ._".-'~~=I ready to use. No aspiration is required because natural diffusion of the heated sensors supplies sufficient air flow. . For testing underground prior to entering, the(- aspirator accessory may be attached to the unit. The hose is placed into the manhole and an air sample is drawn from the area with the aspirator bulb. An alternative method of checking the air prior to entering is to lower the COMBO into the hole and listen for an alarm. FACTORY SET ALARM LEVELS: The COMBO is calibrated to alarm as follows= C'ombustible -Red Light -20% LEL Methane Toxic -Orange Light -10ppm H2S Oxygen Level -Yellow Light' -less than 19.5% 02 SPECIFICATIONS: Sensors: Combustibllt and Toxic: Replaceabllt solid-slate cat~y1ic type. <>2: Replaceable chemiCal cell.

DOLAN General Manager-Chief Engineer DATE May 15, 1980 SUBJECT SEWER SERVICE FOR THE CONSTRUCTION SERVICES BUILDING TYPE OF ACTION APPROVE PLANS AND PROJECT MANUAL DSP 3360 SUBMITTED BY Jay McCoy INITIATING DEPT./DIV. Engineering/Collection Syst. Estimates have been prepared for three methods of sewering the proposed Construction Services Building. The cost of extension of gravity service 1,000 feet to the south to the CCCSD system is estimated at $57,000. The cost of extension of gravity service 300 feet to the west to the Mt. View system including payment of connection fees and 50 years' of service charges is estimated at $62,000. The cost of a pump system to connect to the treat- ment facilities to the east including 50 years' maintenance and power costs, is estimated at $34,000 with no allowance for inflation. 20 percent of the $57,000 gravity alternative ($11,400) can be attributed to the new office building. The remaining $46,600 can be compared to the $34,000 cost for pumping. Keeping in mind that maintenance and power costs will inflate in the coming years and that the basic service policy of this District is the provision of gravity service, the gravity sewer extension to the CCCSD system is appropriate. Mt. View's former concern over minimizing the expenditure of public funds seems to have disappeared. Mt. View does want to come to an agreement on modifications of our common boundary in the vicinity of the proposed building. This agreement can be achieved at staff level. The political aspect of providing sewer service is being solved. Recommendation: Approve plans and project manual and authorize advertising for bids for DSP 3360, Construction Services Building Sewer. INITI T7 Jit;V. REVIEWED AND RECOMMENDED FOR BOARD ACTION e.t.
