If City sampling equipment is unavailable, user <br /> must supply the proper equipment at his own expense. The City <br /> shall retake one sample for each sample taken in the normal <br /> sampling program for a charge equal to the City's expense. <br /> Sampling at the request of the user in greater frequency than <br /> stated above shall be elective on the part of the Supervisor; <br /> charges for such sampling shall be at a flat rate of three times the <br /> City's cost. <br /> The user may request, no later than the onset of sampling, a <br /> split or duplicate of any sample taken by the City for surcharge <br /> calculation or compliance with any portion of this ordinance." <br /> CHARGE RATES FOR EXCESSIVE SURCHARGE <br /> SCRBODS Charge SCRTSS Charge <br /> <br /> dollars/mg/1/million gallons $ .7339 $ .5712 <br /> <br /> (h) Calculation of excessive strength surcharge: <br /> SC- [ (BOD5 mg/1 - 250 mg/1) (SCRBOD 5 ) + <br /> - <br /> (TSS mg/1 - 250 mg/1) (SCRTSS) +(Ammonia mg/1 - 30 <br /> mg/1) (SCR ) ] X MG <br /> ammonia <br /> <br /> <br /> Where : <br /> <br /> SC = Surcharge <br /> BOD5 mg/1 = Average user BODS for surcharge calculation <br /> <br /> 250 mg/1 = allowable BOD5 and total suspended solids concentration <br /> without surcharge <br /> SCRBOD = charge rate for BODS <br /> 5 <br /> TSS mg/1 = Average user TSS for surcharge calculation <br /> MG = User wastewater contribution in million gallons for the month <br /> or the user water usage whichever is applicable. <br /> <br /> SCRTSS - charge rate for TSS <br /> <br /> 30 mg/1 = allowable ammonia level <br /> SCRammonia = (3.22) ( SCRBQD5) <br /> <br /> <br /> <br /> NOTE• The 5CRS5 and 5CRBOD 5 are rates based on one (1) <br /> mg/1 in one (1) million gallons of wastewater. <br /> <br /> <br /> <br /> (i) Shortened capacity life surcharge: Since BOD and 5S <br /> concentrations in excess of 250 mg/1 will tend to use up the capacity of <br /> the treatment plant, there is a cost incurred for the shortened useful <br /> capacity of the treatment plant, which shall be recovered as follows : <br /> <br /> <br /> <br /> <br /> 2 <br />
