GENERAL SUBJECT :  Performance Data for Treatment Technologies for Acid
Mine Drainage

	

TOPICS DISCUSSED AND ACTION TAKEN

Thursday, May 17, 2007 at 1:45 pm, I left a message for Mr. Bob Agnew of
the Pennsylvania Department of Environmental Protection (PA DEP) to
discuss the following items:

Data previously provided from the PA DEP mainframe are untreated
samples;

Untreated ranges (low, medium, and high) for flow, pH, iron, manganese,
magnesium, aluminum, and alkalinity; and

Paired treatment performance data for various active and passive
treatment technologies.

Friday, May 18, 2007 at 10:45 am, Mr. Agnew returned my call.  I asked
Mr. Agnew if the database he provided (5-2-07 Permits With Active MDI
Points And Avg Results.xls) only contained untreated samples.  Mr. Agnew
confirmed that the database was only sampling data from discharges prior
to treatment.  I explained to Mr. Agnew that EPA and ERG needs untreated
ranges for the input parameters in AMDTreat® for each of the model
mines included in the “Model Mine Concept Memorandum” and that EPA
would like PA DEP to provide the ranges.  Mr. Agnew said he could
manipulate the database but would not know if the results provided
accurate ranges for EPA.  Mr. Agnew suggested I contact Mr. Mike Smith
of PA DEP (814-342-8200) to get the input parameter ranges.

I also explained to Mr. Agnew that EPA and ERG would like paired data
for 10 treatment system locations for each type of treatment system
(e.g., 10 mine sites treating acid mine drainage using limestone beds). 
Mr. Agnew said the District Mining Managers would need to provide him
with the mine permit and outfall information to link the untreated and
treated samples together in the PA DEP database.  Mr. Agnew suggested
that I contact Mr. Smith about getting the treatment systems.

Friday, May 18, 2007 at 2:30 pm, I left a message for Mr. Smith to
discuss untreated ranges for input parameters into EPA’s cost modules
and paired treatment performance data.

Friday, May 18, 2007 at 3:00 pm, Mr. Smith returned my call.  I
explained that Mr. Agnew suggested I contact Mr. Smith about obtaining
ranges for input parameters into EPA’s cost modules and obtaining
paired sampling data to determine treatment system performance.  I
explained that EPA’s cost modules are based on input water
characteristics and that EPA wanted stakeholders to provide ranges (low,
medium, and high) for the following parameters:

Alkalinity;

Aluminum;

Flow;

Iron;

Manganese; and

pH.

I said that EPA wanted stakeholders to provide the data to ensure the
ranges were reasonable compared to sampling data.  I told Mr. Smith that
the ranges could be based on best professional judgment or sampling
data, which ever was easier.  Mr. Smith said he would discuss the ranges
with other PA DEP mining staff during a meeting on May 30, 2007.  

I explained that EPA wants treatment performance data for active and
passive treatment systems.  I said that ideally, EPA would obtain
sampling data for 10 mine sites for each type of treatment system.  I
told Mr. Smith that EPA’s priority is obtaining data for chemical
precipitation using caustic and/or lime, chemical precipitation using
lime, and limestone beds (not manganese removal beds), but would also
like information for other treatment systems that have been demonstrated
(e.g., wetlands, vertical flow ponds, manganese removal beds).  Mr.
Smith said he would discuss the treatment systems with the PA DEP mining
staff during the May 30, 2007 meeting.  Mr. Smith stated that he did not
know of 10 limestone bed treatment systems because of the requirements
on the untreated water quality; however, he would discuss it with the
staff.

Mr. Smith asked that I email him the information EPA wanted to remind
him before the May 30, 2007 meeting.

Need to return call by         /         at/between         and
