GENERAL SUBJECT : Hydrogen sulfide, unionized concentrations in DMR 2009



### TOPICS DISCUSSED AND ACTION TAKEN

On Thursday, February 24, 2011, I called the Florida Department of Environmental Protection (FL DEP) to discuss hydrogen sulfide, unionized concentration values and units for the Palm Coast WTP #3 facility in Palm Coast, Florida. I spoke with Monic a Sedano who stated that she would locate the facility permit and send it to
me via e

- mail. Ms. Sedano confirmed that there were no permit limits for the hydrogen sulfide; however, the facility permit required the parameter to be monitored. Ms. Sedano stat ed that she was not sure why this monitoring requirement was included and suggested that I contact FL DEP Northeast District, who was responsible for writing the permit.

On Monday, February 28, 2011, I called the FL DEP Northeast District and spoke with J oseph Emery who was involved with drafting the facility permit. Mr. Emery stated that Outfall 001 discharges reverse osmosis reject concentrate. The treatment of the concentrate may include degasification to remove hydrogen sulfide. The

concentrate is ulti mately discharge d to the Intercoastal Waterway, Class III Marine waters. Mr. Emery stated that a permit modification was made to included hydrogen sulfide monitoring because of the location of the discharge (sea water islands). Mr. Emery also stated that t his plant operation just began in 2009, which is why there is no historical data for the hydrogen sulfide discharges.

Mr. Emery was unable to explain why the permit required the hydrogen sulfide, unionized concentrations to be reported LB/1000GA, but conf irmed that this unit was pounds of hydrogen sulfide per 1000 gallons of water. He stated that he helped the plant determine the conversion of mg/L to LB/1000GA. I asked Mr. Emery for the conversion information that was developed for the plant. Please see t he attached files.Email Correspondence with FL State, Palm Coast WTP #3

Elizabeth, I looked at the DMR we have in our office and those are the results for the months. Peter Roussell is the lead operat or I have spoken to, his email is proussell@ci.palm

- coast.fl.us<mailto:proussell@ci.palm

- coast.fl.us>. Pete is pretty good about answering my email, sometimes it might take a day or so. Also I attached what I pull from our database on results (DMR) tha t they are required by permit to report to DEP. Any more question pleas e do not hesitate in contacting me. Have a good day and sorry it took me so long to get back to you. Joseph C. Emery, P.E. Department of Environmental Protection

Joe,

I was wondering if you were able to take a look at these values regarding the DMR 2009 data for Palm Cost WTP #3. If you are unable to confirm the data, do you know a plant contact that I would be able to get in touch with?

Thanks,

Elizabeth

>>> Elizabeth Sabol 2/28/2011 3:17 PM >>> Hi Joe,

Thanks for the spread sheet with the conversions. I have one follow

- up question for you regarding the data for the Palm Coast WTP regarding the values/units of the submitted data. I am unclear what units our information is actually reported in. From your conversion she et, these may be mg/L or LB/1000GA. Could you please co nfirm the values and units for the 2009 H2S concentrations?

Outfall 001, PRAM 51078:

30 June 2009: 2.8 31 July 2009: 1.9731 Aug 2009: 25 30 Sept 2009: 3.5
31 Oct 2009: 5.7
30 Nov 2009: 1.9
31 Dev 2009: 1.9

All unit s LB/1000GA. If any of these units or values are incorrect, please provide the correct data.

Thanks,

Red Text - Potential error identified in the OTIS data. The utility is the Palm Coast Utility and it operates 3 WTPs. We have survey data for WTP#1 and #2 but not WTP#3 (the one you reference). The discharge from WTP3 is membrane concentrate and I would expect they are removing the hydrogen sulfide from the groundwater and that is why you have a high amount. I did not see the NPDES permit (FL0454451) with our permits, but will check if I can find via EPA online.

Website for the utility is: http://www.ci.palmcoast.fl.us/Government/Departments/Utilities/WaterOperations.aspx It just provides brief details of the operation. Obtain facility permit and determine if this pollutant is a prodcution based limit. Determine if we should exclude from rankings.
