RAY CITY MANAGER FROM: F. ROBERT CARR PUBLIC WORKS DIRECTOR SUBJECT: DISINFECTION EQUIPMENT REPAIRS (WASTEWATER TREATMENT PLANT) DATE: February 14, 1995 BACKGROUND: Over the past 18 to 24 months, three of the existing eight ultraviolet disinfection modules at the Wastewater Treatment Plant have failed. These modules were installed initially when the plant was constructed in 1988. Under normal operating conditions, four of the units operate continuously with two units working only when flows increase through the plant. Failure of the units has been largely caused by the cable leads shorting. Instrumentation including the lamp indicator boards and mother boards have also sustained damage. With increasing growth in the community and associated increases in wastewater flow to the plant, the operation of these units is important to ensure the plant discharge continues to meet required disinfection standards. PROJECT COSTS: Costs to replace and /or repair the inoperable units have been assembled. Infilco Degremont, Inc., Richmond, Virginia, is the sole builder and supplier of parts for these units and has provided costs for replacement parts and repairs. Infilco supplied the original parts when the plant was constructed. Costs for labor to install the required parts and for replacement of the electric cables has been provided by Haynes Equipment Company, Inc., Oklahoma City. Haynes Equipment is considered a sole - source repair company for instrumentation at the plant. They installed the original plant equipment and have been providing maintenance since initial plant start-up and are familiar with all the components requiring replacement. Page 2 Wastewater Disinfection Equipment Repairs The total cost of parts is $2,057.02 from Infilco Degremont (see attached proposal). Costs of labor /replacement from Haynes Equipment is $2,634.58 (see attached proposal). Based on these individual proposals, the total project cost is expected to be $4,691.60. FUNDING: The Wastewater Treatment FY 94 -95 Budget includes $6,500 in Operating Supplies (61 -530- 5220) for these expenses. RECOMMENDATION: Staff recommends Authority approval of a sole- source purchase of repair and replacement parts and installation labor for the ultraviolet disinfection modules at the Wastewater Treatment Plant in the amount of $2,057.02 for parts from Infilco Degremont, Inc., Richmond, Virginia and $2,634.58 for labor and replacement materials from Haynes Equipment Company, Inc., Oklahoma City, Oklahoma.

Their company had a long history going back to the 1930's. Previously, it was known as Ultraviolet Purification Systems (UVPS). IDI is the sole licensee for the Katadyn/UVPS Ultraviolet Disinfection Equipment in the United States, Canada, and throughout the world. Infilco Degremont was established as International Filter Company in November 1894. This name was later shortened to Infilco and, in 1974, Degremont S.A. acquired the company and created IDI. Degremont is one of the largest water and wastewater treatment equipment companies in the world, so we have access to a great deal of technology, experience and information. In order to support our UV customers in the field, we have a well established full -line inventory of lamps, jackets ballasts, circuit boards and gland seal assemblies in our Richmond, Virginia, warehouse. When you place your UV parts order with IDI, we can ship from our shelf stock without delay and long - waiting periods.

PUBLIC WORKS DIRECTOR SUBJECT: AIR MONITOR PURCHASE DATE: February 14, 1995 BACKGROUND: As part of the City of Owasso confined space entry program, the Public Works Wastewater Collections Division has been utilizing a Gas -Tek Air Monitor for approximately eight (8) years. This unit provides for the constant testing of air quality while men are working in a confined space (i.e., sewage lift station, water valve vault or manhole). The air monitor tests for the amount of oxygen, hydrogen sulfide, carbon monoxide, and combustible gases in the atmosphere. Testing is a requirement by the Office of Safety and Health Administration (OSHA) for confined space entry. Over the past ninety (90) days, the air monitor has failed on three occasions. According to the manufacturer, the Gas -Tek air monitor already has been used three years-past its life expectancy. These failures prevent the men from working in the confined space. Loaner units have been borrowed from the City of Tulsa two times during this period so that we could continue to perform normal duties while repairs were being made. Staff believes however, that we need to have our own monitor, rather than relying on the graces of our friends in Tulsa. REPAIR COSTS: On October 25, 1994, we sent in the existing monitor for repairs. At that time, sensors were replaced for $542.00 and the unit was returned to us in 5 weeks. Unfortunately, additional parts failed the next time we went to use the monitor. It was estimated that it would cost $135.00 to repair the unit once again. Staff began to evaluate the option of replacing the unit with a new model at that time. REPLACEMENT PRICES: Prices for a replacement air monitor were solicited. Boren Safety Products of Tulsa, Oklahoma has two different models available. Lumidor Safety Products of Miramar, Florida has one model available. Page 2 Air Monitor Purchase Both manufacturers use an electro - chemical type of sensor. The sensors are manufactured in a way which provides accurate measurements of gas levels on a consistent level; however, each time the sensor is exposed to the type of gas it is designed to test, the life of the sensor is diminished. Repeated exposure to hazardous atmospheres determines the life expectancy of the sensor. Both Boren Safety Products and Lumidor claim the life expectancy of the hydrogen sulfide and carbon monoxide sensors to be 12 to 18 months. The oxygen and combustible gases sensors can last up to 24 months. Sensors on all three models can be serviced in the field, greatly reducing down time. A self- diagnostic calibration kit is available with each model. These kits enable field personnel to introduce a specific amount of air with known quantities of contaminates into the unit to check the accuracy of sensors. The field personnel can then determine whether the monitor would achieve the proper calibration and reading. Calibration is checked prior to determining the condition and safety of the confined space about to be entered. COSTS COMPARISON: To evaluate overall monitor costs, expenses of replacing sensors at regular intervals needs to be considered. A tabulation of both monitor and sensor costs are shown below: Monitor Cost Supplier Product Price Price of Self Test Kit Total Price Limited Warranty Boren Omni -4000 $1,870 $395 $2,265 1 year Boren Crow -Con Triple Plus $1,850 $445 $2,295 1 year Lumidor Micro -Max $1,795 $385 $2,180 2 year Sensor Cost Hydrogen Carbon Total Prorated Product Oxygen Combustibles Sulfide Dioxide Price Yearly Replace- ment Cost Omni -4000 $165 $335 $260 $295 $1,055 $805 Crow -Con Triple Plus $125 $295 $260 $295 $ 975 $765 Lumidor Micro-Max $133 $210 $295 $295 $ 933 $762 Page 3 Air Monitor Purchase Additional Information Product Dust Proof Water Resistant Floats Omni -4000 No No No Crow -Con Triple Plus Yes Yes Yes Lumidor Micro -Max Yes Yes No Monitor costs include the self - diagnostic calibration kit for each unit. These kits are not interchangeable between suppliers and monitors. Sensors are required to be replaced as operating conditions vary (from 12 -24 months). each type of sensor was evaluated and a prorated yearly cost to replace all the sensors was calculated. Both the air monitor cost and sensor replacement costs were lowest from Lumidor Safety Products. The Lumidor Micro -Max monitor with self - diagnostic calibration kit costs $2,170.00 with a 2 -year limited warranty. The sensor yearly replacement cost is $762.00, but expenditure for replacement is not anticipated for another 12 -18 months. Replacements will be included in future operating budgets. FUNDING: Purchase of this equipment was not anticipated in the FY 94 -95 Budget, but the monitor is essential to safe entry into confined spaces. Funds for the purchase will be determined based on re- prioritization of needs within the existing Water and Wastewater Division budgets. RECOMMENDATION: Staff recommends the Authority approve the purchase of a Micro -Max Monitor and self test ' kit from Lumidor Safety Products, Miramar, Florida in the amount of $2,170. ATTACHMENTS: 1.

I have three prices on three different air monitors. The first one is a Micro Max gas monitor by Lumidor Safety Products. The price is $1,795.00. An additional cost of $385.00 for a calibration kit will be added. The total cost will be $2,180.00. The next one is an Omni -4000 by the ENMET Corporation;` at a price of $1,870.00. An additional cost of $395.00 for a calibration kit will be added on. The third one is a Triple Plus gas monitor by CEA Instruments, Inc. at a price of $1,850.00. An additional cost of $445.00 for a calibration kit will be added on. I have reviewed all three air monitors and believe that the Micro- Max monitor by Lumidor Safety of Miramar, Florida is the one we should purchase. It is least expensive, is more economical to maintain and carries a longer warranty than the others. MEMORANDUM TO: HONORABLE MAYOR AND CITY COUNCIL CITY OF OWASSO FROM: SHERRY BISHOP FINANCE DIRECTOR SUBJECT: OPWA SALES TAX FUND BUDGET AMENDMENT IAND TRANSFER DATE: February 17, 1995 BACKGROUND: All proceeds of the third penny of sale tax are restricted by ordinance to be used only for debt ervice or capital improvements. Throughout the year, the third penny is deposited in the OPWA Sales Tax Fund and the debt service on the OPWA 1988 Revenue Bonds is paid monthly from that account. When enough money has accumulated in the Sales Tax Fund to assure the monthly debt service payments for the rest of the fiscal year, then any additional money in the Sales Tax Fund is considered "excess." "Excess" money in the Sales Tax Fund may be transferred to the city's Capital Improvements Fund for appropriation to projects. With the receipt of the February sales tax check, the balance of the Sales Tax Fund is $290,427. Debt service payments to be made for the remainder of the fiscal year (March through June) total $200,412. That leaves an "excess" of $90,015 that may be transferred to the Capital Improvements Fund. Normally that transfer would not occur until after the adoption of next year's budget and the funds would be used to pay for the 1995 -96 Capital Improvements projects approved by the Council. However, this year the Council authorized the staff to solicit bids for additional lighting to the softball fields. In order to fund the project, (see items #12 & #13, City Council agenda) an additional $44,000 must be transferred to the 1994 -95 Capital Improvements Fund budget. If approved, the effect of this action is to borrow from next year's Capital Improvements money, so the lighting project can be completed now. Sales Tax Fund Budget Amendment February 17, 1995 Page 2 RECOMMENDATION Staff recommends Council approval of a supplemental appropriation from the OPWA Sales Tax Fund to transfer to the Capital Improvements Fund of $44,000; and approval of the payment of that transfer.
