Ms. Sabol, 

After reviewing the data it, there is an error in how the data was entered in the system. The information was transferred from Missouri's old 

WQIS to the new MoCWIS system and the data from the permit requires micrograms per liter (ug/L) however the data in MoCWIS is listed as 

milligrams per liter (mg/L). It appears that when this information was transferred it was entered in the ug/L value instead of converting it to 

mg/L format. Below is a breakdown of the data that was submitted by the facility. 

Outfall #001: 

Flow 0.144 MGD 

Magnesium 7.22 mg/L 

Manganese 0.116 mg/L 

Outfall #002: 

Flow 0.0864 MGD 

Manganese 0.429 mg/L 

Magnesium 12 mg/L 

Fluoride 0.4 mg/L 

Boron, Total Recoverable was also entered as 86.9 mg/L and should have been entered as 0.0869 mg/L. 

I have went in and corrected the data to accurately reflect the digits in the mg/L value. Also I have attached a copy of the facility's submitted 

Discharge Monitoring Report. 

If you have any additional questions, please let me know. 

Thank you

Subject: DMRs Clarification Needed for Onyx Maple Hill Landfill 

Dear Mr. Tipton, 

Thank you for your time on the phone yesterday. Eastern Research Group, Inc. (ERG) under EPA Contract No. 68-C-02-095 is e-mailing you 

on EPA's behalf to request clarification of 2008 discharge monitoring reports for the Onyx Maple Hill Landfill in Macon, MO (MO0117471). 

Here is some background on what the information is used for. 

EPA reviews publicly-available DMR data to fulfill its review obligation under Section 304(b) of the Clean Water Act. The CWA requires EPA 

to annually review and, if appropriate, revise its water pollution control technology-based regulations, called "effluent limitations guidelines" or 

"effluent guidelines," that limit the discharge of pollutants to waters of the U.S. from various categories of industrial facilities. EPA is currently 

conducting its 2010 annual review of existing effluent guidelines and potential industrial guidelines which may need to be included (see 

http://www.epa.gov/guide/304m/ for further information). EPA will discuss this review and the results in its 2010 Effluent Guidelines Program 

Plan scheduled for publication in the Federal Register in December 2010. As part of the 2010 annual review, EPA is evaluating the data in 

discharge monitoring reports from 2008 and needs further information to complete the review. 

We would like to obtain additional information on the following concentration data for manganese, magnesium, and fluoride discharges from 

your facility. Our records show the following concentrations were discharged: 

Outfall 001: 
Manganese (Sept 2008): 116 mg/L 

Magnesium (Sept 2008): 7220 mg/L 

Average Reported Flow: 0.0864 MGD 

Outfall 004: 

Manganese (Sept 2008): 429 mg/L 

Magnesium (Sept 2008): 12000 mg/L 

Fluoride (Sept 2008): 400 mg/L 

Average Reported Flow: 0.144 MGD 

We appreciate your help in confirming if the above data are accurate, or if there are units errors in the DMR data, as we expect. 

If you have any questions regarding this request, please call me at (703) 633-1659. If you would like to speak directly with EPA regarding this 

request, you can contact William F. Swietlik of EPA's Office of Water/Engineering Analysis Division by phone at (202) 566-1129 or by email: 

swietlik.william@epa.gov<mailto:swietlik.william@epa.gov>.
