STANDARD OPERATING PROCEDURE

OPERATIONAL CHECKS: SEWAGE TREATMENT SYSTEM

All operational checks, maintenance and repair of lift stations shall be conducted in accordance with specifications in the Shenango Lake Sewage and Water treatment Facilities Operation and Maintenance Manual.

Overall Visual Check: Immediately upon opening and entering the Sewage Treatment Plant, conduct a visual and auditory check of all operations and equipment to check for conditions requiring adjustment, maintenance, or repair.

Grit Chamber. Clean and hose the grit chamber twice daily from mid-May through early October.

Check and Adjust Diffusers. Visually check diffusers once a day from mid-May through early October and adjust the diffusers if clogged with sludge or if over aerating.

Check, Clean and Backwash Wire Screens (tertiary) Between the Clarifier and Chlorine Tank.

Check wire screens between the clarifier and chlorine tank once daily. Screens shall be cleared of all seeds and debris at least once daily (backwashed). Checks and adjustments shall be conducted between mid-May through early October.

Check Water Height in Aeration Tank. Check water height in the aeration tank once daily from mid-May through early October. Water height should in accordance with manufacturer specifications. If not, check for blockage and clear as necessary to maintain correct height.

Check and Clean Gate Valves between Clarifier and Aeration Tank. Check gate valves one time a week, during each week services are ordered, and clear, repair, or replace as necessary to maintain acceptable water levels in aeration tanks.

Removal of Sludge. Monitor the level of sludge in the aeration tank by means of a visual check at least once a month. Arrange for removal of sludge as deemed necessary for the proper operation of the plant.

Add Lime to Restore pH Levels to between 6.05 and 9.0 standard units. This shall be done as needed as determined by pH tests.

Adjust Blower Time. Increase or decrease the operating time of blowers at least three times a week and more often as necessary to maintain oxygen levels within standards. Monitor the results of the daily dissolved oxygen test and adjust blowers within one hour of test results in order to reestablish required oxygen levels. Adjustments shall be made during each week the services are ordered.

Adjust Chlorine Levels. Monitor chlorine levels using the results of the required daily chlorine residual test. Adjust chlorine levels to attain standards within one hour after tests indicate the need. Levels shall be adjusted by decreasing chlorine dosage or increasing chlorine dosage.

Monitor Imhoff Test Results and Adjust Skimmer and Return Sludge. Monitor the results of the daily Imhoff test and check skimmer and return sludge when test results are not within standards.

Skimmer and return sludge shall be checked for adjustment and blockage. Blockages shall be cleared and equipment adjusted as necessary within one hour of daily test results.

Monitor Settlable Solids Test Results and Operate Skimmer, as Necessary. Monitor the results of the daily settlable solids test and, when not within standards, check return sludge and skimmer. Adjustments shall be made to reestablish settlable solids levels within standards.

When settlable solids comprise 60%, arrange for waste sludge removal.

Check and Maintain Blowers. Check all blowers daily by 9:30 a.m. to ensure proper operation and identify maintenance needs. Add oil (30 weight, non detergent), adjust belts, and grease blowers (bearings) as necessary to ensure proper operation and maintenance. Oil level and belts shall be checked daily. Blowers shall be greased at least once a week.

Clean STP Equipment. Thoroughly clean STP equipment to ensure compliance with applicable health and sanitation regulations and ensure proper operation. Clean the influent channel, aeration tank sides, grating on aeration tank, clarifier, chlorine tank and grating, clean out the cylinder chamber on top of the clarifier, double bag and dispose of the debris through proper methods.

Clean STP Premises. Clean and maintain the STP premises and equipment in a neat and orderly manner at all times. This will include but not be limited to removing dirt, grease, oil, empty containers, spills, rags, dust, cobwebs and clutter from the facility. Tools and supplies will be neatly stored. The STP floor, counter tops, walls, doors, windows, and general work area will be cleaned at least once a week and more often as needed to ensure proper operation and compliance with safety, health and sanitation regulations.

Winterize STP. Specific winterization tasks are detailed below.

o Remove, clean, recoil, and replace air filters.

o Cover air conditioners with metal cover boxes, if applicable.

o Put tires in aeration tanks, holding tanks, and clarifiers. Secure tires to prevent sinking.

o Take water hose off faucet and store in plant.

o Clean out leaves and other debris from gutters on STP.

o Turn on heater in STP and adjust thermostat to temperature designated by COR.

Dewinterize STP:

o Unclog the air filters and replace, grease threads as necessary o Uncover air conditioners, remove tires, grease and lubricate gate and check valves if necessary. Check and replace damaged diffusers o Install water hose o Turn off heater.

Manholes and Confined Spaces. Check for dangerous levels of methane and adequate levels of oxygen in manholes and confined spaces prior to entering for any purpose. Safety checks shall be conducted, before and during the work, using a gas indicator in accordance with manufacturer's instructions. Workers are not to enter any space where a known hazardous condition exists. Systems will be locked out/tagged out as required prior to entering any confined space, and proper ventilation will be provided. Safety guidelines in EM 385-1-1 will be followed.

Minor repairs will be initiated as necessary to maintain station operation. Contaminated oil will be drained and fresh oil will be added to the proper level; overfilling oil may cause pressure build-up and void any warranties.

o Check impeller for dragging, binding, pitting, or excessive wear. Clean out the impeller body if necessary.

o Perform an inspection of all gate valves in the piping system for binding, seizing, or irregular operation and repair as necessary.

o Check holding tank. Conduct a visual check of the holding tank for leakage, cracks, and corrosion and make all necessary repairs to prevent leakage.

o Check holding tank water levels. Conduct a visual check of holding tank water levels to ensure proper operation of the system and detect blockage or pump problems.

Water levels shall be within manufacturer's guidelines. If necessary, check and adjust the pump floats for proper operation or make other repairs to return water levels to specifications.

o Visual check of fence and gates. Ensure that the fencing and gates around the ejector stations are intact and will not permit unauthorized entry. The gates are to be kept locked when authorized personnel are not present.
