TOPICS DISCUSSED:
Welcome and Administration

1. Introductions were made.
2. Lunch Arrangements were made.
3. Approval of Meeting Summary - June 15, 2004 teleconference: final version distributed at today's meeting includes corrected name spellings. Jim moved, Gary P. second approval of 6/15/04 meeting summary. Unanimously approved.
4. Approval of Meeting Summary - July 6, 2004 meeting: Three changes needed: 1) Jim noted - Act 202 should read Act 220; 2) Leroy noted - insert "Understanding Instream Flow Protection" to replace and correct the title of his presentation; 3) Curtis noted - pg 2, Key outcomes, USGS tool, sentence reading "Does not address areas where…" is incorrect; the tool will address these areas. Strike "does not address areas" and insert at end "other methods besides regionalization will be developed". Jim moved, Leroy second approval of 7/6/04 meeting summary with revisions noted. Unanimously approved.
5. "Guidelines for Subcommittee Activities" - was provided as approved by Statewide Committee and was briefly reviewed.
6. Public comments - none.
7. Update on Responses Received to Subcommittee's Request to Regional Committees and river basin commissions for "Locations/Areas of Concern" - Sue passed out a compilation of responses received to date, plus separate SRBC response. DRBC response embedded in Greg's presentation and will be provided later.
8. Member assignment updates:

Preston L. - was asked to research water utility and water consumption information. He provided handouts of 2 AWWA studies. Although neither study included PA specifically, these provide useful information on residential water use patterns and end uses of water from a nationwide perspective. Preston was also asked to prepare an alternative organization of the DEP discussion paper on criteria, which will be discussed later in the meeting.

Jim M. - was asked to research agricultural water use projections, and has made a number of contacts. Not a lot of hard data are available for future water use projections. Developing such projections is a key component of Act 220. He has been referred to SRBC and DRBC for possible previous work on projections and will follow up on this. A meeting is being held today between DEP and PDA and USDA regarding Act 220 agricultural issues, and will include discussion on water use projections.

Gary P. - was asked to research power electric generation projections, and has made contacts including Electric Power Generators Assoc. and will have a conference call with them next week. He is awaiting feedback on generation projections.

Gary M. - was asked to research water use projections for the mining industry. He has contacted the PA Coal Association and PA Aggregate and Concrete Association and will continue looking into this and report back.

DEP noted that with Act 220, the PA legislature provided funding to SRBC and DRBC to assist DEP with developing water use projections and these agencies will be working together on this.

Overview of Ground Water Withdrawal Regulatory Criteria (Cavallo and Brownell)
Greg Cavallo provided an overview of DRBC's experience in developing and implementing the GWPA ground water withdrawal regulations and criteria, focusing on use of the 1 in 25 year baseflow statistic. Greg indicated that by applying the GWPA criteria and regulations, the Warminster, Upper Reach Wissahicken, Ironworks Creek subbasins are "stressed" in GWPA, based on net ground water withdrawals. DRBC will provide a list of areas that reflects DRBC's response to request for basin-wide "potential areas of concern" based on results of ongoing USGS analyses of Delaware basin and will provide that to the Subcommittee.

Mike Brownell provided an overview of SRBC's approach to applying criteria for ground water withdrawals in their jurisdiction, focusing on the 1 in 10 year average annual drought recharge rate. Mike and Bob Pody presented a graph and table comparing various "criteria" to illustrate the range of variation between different baseflow recurrence intervals and discussed reasons why the curves become asymptotic.

Effects of Ground Water Pumping on Streamflows - French Creek , Southeastern PA (Cavallo)
Greg provided an overview of the results of a recent USGS study on inter-relationship (magnitude and timeframe) of ground water pumping and stream baseflow.

Critical Water Planning Area - Understanding of Definition

Brief review of Act 220, Sect. 3112 (A)(6) "The State Water Plan and Regional Plan shall include (6) An identification of critical water planning areas comprising any significant hydrologic unit where existing or future demands exceed or threaten to exceed the safe yield of available water resources."

Jim noted that commercial/industrial water uses have not been addressed in our research. Bill Gast indicated that PADEP is researching this via various industrial and commercial organizations, etc. Gary P indicates that the commercial/industrial projections will be directly relevant to the power generation projections.

Mike also noted that mining (which was second largest water withdrawal in 1995 in Susquehanna Basin) uses and projections have not been addressed. Bill indicated that PADEP is looking into mining uses as well. Gary Merritt has been looking into this and has contacted PA Coal Assoc. and PA Aggregate and Concrete Assoc. and will continue looking into this and report back.

Pam noted that Act 220 defines "safe yield" as including both "withdrawal" and "nonwithdrawal" uses and the Act defines the latter to include, but not be limited to, "aquatic resources, navigation, recreation," etc. PADEP is pursuing navigation uses with USACE and on recreation uses with PA DCNR.

Bill also noted that DRBC and SRBC will be looking into these demands data as well along with PADEP.

Jan noted that the timeframe for exceedance must also be addressed.

Review of organization of Criteria discussion papers. Consensus was reached that the both outlines are useful and they will be merged as the content is addressed.

Planning area size: initial concept - minimum size of the hydrologic unit being nominated as a CWPA to be 15 sq. mi. Some concerns remain that this may eliminate smaller areas that have a significant problem; further discussion needed.

Timeframe in which the exceedance is likely to occur: initial concept - 5 years (for nominations during preparation of plan) and 20 years (for nominations identified through the planning process). This concept received general consensus, but will be further discussed.

Bill, Leroy, Mike, and Greg agreed to work together to draft a "strawboss" of the combined criteria document for the next meeting, taking into consideration the previous drafts by both Bill and Preston, and the discussions of the Subcommittee.

Sue distributed copies of the existing State Water Plan "Planning Principles" for the Subcommittee's reference.

Bill anticipates that available methodologies for developing demand projections will be collected by October 2004. Projections for a 20 year planning period are desired by DEP.

Adjourned 3:10 p.m.

NEXT STEPS:

1. Greg Cavallo will provide a short written summary and map of DRBC's list of "potential areas of concern" that includes areas of potention GW withdrawal, surface water withdrawal, and/or water quality concerns.
2. Jim M - will continue to pursue agricultural water use projections information
3. Gary P - will continue to pursue electric power generation water use projection information.
4. Gary M - will continue to pursue mining industry water use projection information.
5. Bill, Leroy, Mike, and Greg will draft a "strawboss" of this document for the next meeting, taking into consideration the previous drafts by Bill and Preston, and provide this to Jan for distribution to Subcommittee one week prior to next meeting.
6. PADEP (Bill and Pam) will try to review Preston's draft "process" papers and provide their reaction on consistency with statute, etc. for the next meeting.


NEXT MEETING: September 2, 2004, (10:00 to 3:00) USGS Offices, New Cumberland, PA.
