Mike,
FYI, since you may have to analyze possible treatment options for impacted facilities.

Attached bthe latest version ofmyanalysis ofthe proposed regulation's impact onNPDESpermits.
I have inserted the industrial sections (majors & minors) directly into the body of the report. All the tables are attached
in this email as well. Connie, | tried to correct some of my numbers so that iswhy you will see some slight percentage
changes. I would be glad to tell you exactly how I made these calculations
Two points:
1) Jeff has discussed what isneeded from Pretreatment Pretreatment Permhteesimpacted at1Oin-stream and
10 effluent hardness verses Pretreatment Permittees impacted at median in -stream and median effluent
hardness. | will insert that inmyreport when they are finished.
2) Dianne regarding Chuck's question on how my analysis would change if median hardness values were used. My
report isbroken into six sections asfollows:
Municipal WW'17Ps 295 (128Pretreatment POTVVn; 121 minor municipals; 4Omajors wiUhoutpmtneaUnontpmgremu)
luduobda|W\y7Pemajor —SG
Industrial 9yW7Peminor - !S|
Private |0OY6dorneeUoW\y7Pe-48?
Groondvva1arrannorhatioo rhaohurgoo - 38
Water TraoknouiPlant discharges - 819
Just soeveryone bclear I did my review assuming a hardness value of 25 mg1L for all groups except Municipal majors
with Pretreatment Programs. For thePretreatment POTVVsw/ewere able to find enough effluent hardness values to
establish a 1OY6hardness and a median. | can certainly re-evaluate the 4G majors under both scenarios and extrapolate
to see if similar differences would change groundwater and VVTP facility results. | will try todothis over the next 3-4
weeks.
Ifyou have any questions onthe attachments, please let meknow.
