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 Monica 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 stated 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 Joseph 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 ultimately discharged 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 this 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 confirmed 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 the attached files.

Elizabeth,

I looked at the DMR we have in our office and those are the results for the months. Peter Roussell is the lead operator 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) that 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.

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

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 sheet, these may be 

mg/L or LB/1000GA. Could you please confirm the values and units for the 2009 H2S concentrations?

Outfall 001, PRAM 51078:

30 Apr 2009: 0.021

31 May 2009: 0.021

30 June 2009: 2.8

31 July 2009: 1.97
31 Aug 2009: 25

30 Sept 2009: 3.5

31 Oct 2009: 5.7

30 Nov 2009: 1.9

31 Dev 2009: 1.9

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

Thanks,

Liz

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.
