Supplementary Information
On March 9, 1999, the Commission held public hearings on proposed amendments to its Ground Water Protected Area Regulations for Southeastern Pennsylvania as noticed in the Pennsylvania Bulletin issues of February 6, 1999, and March 6, 1999. The Commission has considered the extensive testimony and comments from interested parties and has prepared a ''Response Document on Proposed Amendments to the Ground Water Protected Area Regulations for Southeastern Pennsylvania: May 1999'' which is available upon request to Susan Weisman at the number provided above.
The Commission's Ground Water Protected Area Regulations for Southeastern Pennsylvania are hereby amended as follows in the following Resolution.
A Resolution to amend the Ground Water Protected Area Regulations for Southeastern Pennsylvania by the establishment of numerical withdrawal limits for 62 subbasins which are entirely or partially within the Protected Area.
Whereas, the Ground Water Protected Area (GWPA) Regulations for Southeastern Pennsylvania were adopted in 1980 to prevent the depletion of ground water, protect the interests and rights of existing water users, and balance and reconcile alternative and conflicting uses of the limited water resources in the area; and
Whereas, while the GWPA Regulations have successfully addressed most ground water problems, certain provisions, particularly those pertaining to the protection of low streamflows, have been difficult to administer on a project-by-project basis; and
Whereas, the United States Geological Survey (U.S.G.S.) conducted a water-use analysis for the Neshaminy Creek Basin and the Commission's Ground Water Advisory Committee developed proposed amendments to the GWPA Regulations to establish numerical ground water withdrawal limits on a subbasin level based upon baseflow frequency analyses prepared as part of the U.S.G.S. study; and
Whereas, on January 28, 1998, the Commission adopted amendments to its GWPA Regulations which established a two-tiered system of withdrawal limits for the 14 subbasins in the Neshaminy Creek Basin in the Protected Area; and
Whereas, the U.S.G.S. prepared a similar study which investigated the withdrawal limits for the remaining subbasins in the Protected Area and formed the basis of proposed amendments to the GWPA Regulations; and
Whereas, the Commission held public hearings on March 9, 1999, in Conshohocken, Pennsylvania, to receive testimony and comments on the proposed amendments; and
Whereas, a total of 33 comments were received on the proposed amendments; and
Whereas, the Commission has considered the testimony and comments from interested parties; now therefore
Be It Resolved by the Delaware River Basin Commission:
1. The Ground Water Protected Area Regulations for Southeastern Pennsylvania are hereby amended as follows:
Subsection 6.I.3. is hereby revised to read as follows:
3. The potentially stressed levels and withdrawal limits for all delineated basins and subbasins are set forth below:
