Total residual chlorine may not be discharged from any single generating unit for more than twohours per day unless the permittee demonstrates tothe Department that discharge for more than two hours isrequired for macroinvertebrate control. Simultaneous multi-unit chlorination is permitted. Monitoring shallbe performed during periods of chlorination but atleast 60 minutes after the beginning of chlorination andshall be performed using the amperometric titrationmethod. Monitoring is not required on days whenchlorination does not take place.(5) To be calculated as follows: MBtu/day = MillionBtu/day = the sum of the hourly heat calculations.Thehourly heat calculations shall be based on the instantaneous temperature and flow readings according to thefollowing equation: hourly heat rejected = 0.348 X(temperature difference) X (flow in mgd). Temperaturedifference is defined as the instantaneous temperature difference between the intake and the outfall at thebeginning of each hour. Flow shall be the instantaneous flow at the beginning of each hour.

(c) For unstabilized areas of the facility whe re sweeping is not practical, storm water management devices su ch as sediment traps, vegetative buffer strips, filter fabric fence, sediment filtering boom, gravel outle t protection, or other equivalent measures, thatPermit Number: 90-DP-0064

Page Number: 35

effectively trap or remove sediment should be

considered.

iii. Source Controls. The permittee shall consider preventive measures to minimize the potential exposure of all significant materials to precipitation and storm wa ter runoff. The permittee should consider in a narrati ve description the implementation of the following mea sures to reduce the exposure of all materials to storm water :

(a) Relocating all materials, including raw ma terials, intermediate products, material handling equipment, obsolete equipment, and wastes currently stored

outside to inside locations.

(b) Establishment of a schedule for removal of wastes and obsolete equipment to minimize the volume of these materials stored onsite that may be exposed to stor m

water.

(c) Substitution of less hazardous materials, or materials less likely to contaminate storm water, or substitution of recyclable materials for nonrecyclables wherever possible.

(d) Constructing permanent or semipermanent co vers, or other similar forms of protection over stockpiled materials, material handling and processing equipme nt. Options include roofs, tarps, and covers. This may

also include the use of containment bins or covered dumpsters for raw materials, waste materials and nonrecyclable waste materials.
