SUbject: recommendation 

Rob 

Sill just left you a voicemail regarding this recommendation. At this point, Alvin has sufficient documentation to believe 

Rio Pluma has violated their discharge permit in the following two major ways: 

.> changing the TSS sampler code and accessing the TSS sampler; and 

~ conecting and storing TSS samples themselves versus the permit requirement that only the City and certified lab 

control the chain of custody 

Thus, the data from Rio Pluma is not reliable or vafid,as documented in City acquired grab sampling. Routinely, Rio 

Pluma has exceeded their discharge limit of 200 mgll for TSS. This week the City has again locked down the sampling 

equipment and has taken control of their chain of cUstody. . 

In order to protect the City from potential violations of th~ City's discharge permit and possible fines, we recommend that a 

Notice of Violation be issued to Rio Pluma as soon as possible. This will serve three main purposes: 

);> it will show the RWQCB that the City is doing everything it can in order to comply with the City's discharge permit; 

.> it wiU form a. basis for documenting any future expenses incurred by the City to deal with the excess Sludge at the 

WlNFPthat should be reImbursed by Rio Pluma; and 

);> it will give Rio Plums an opportunity to work with the City as well as on their own to solve this problem in the best 

manner, without any RWQCB fines or City surcharges. 

In an effort to get a cost estimate for the removal of the accumulated solids, a representative from Synagro is in the area 

toda.y and I h~ve recommended to AI that he stop by to help develop an estimate. We are also looking at getting 

additional estimates from other responsible solids handling companies. .

RE:recommendation 

The polishing pond should be the first priority. If Rio Pluma or the City want to try the enzyme, this may help on the 

aerated pond.

It would seem that getting the ponds dredged is the best option at this point (?). Should we get both or just the 

polishing pond?
