DELAWARE RIVER BASIN COMMISSION

[ 25 PA. CODE CH. 901 ]

Amendments to the Water Quality Regulations, Water Code and Comprehensive Plan to Update Water Quality Criteria for Toxic Pollutants in the Delaware Estuary and Extend These Criteria to Delaware Bay

[41 Pa.B. 3187]
[Saturday, June 25, 2011]

Summary:

By Resolution No. 2010-13 on December 8, 2010, the Delaware River Basin Commission (DRBC or ''Commission'') approved amendments to its Water Quality Regulations, Water Code and Comprehensive Plan to update the Commission's human health and aquatic life stream quality objectives (also called ''water quality criteria'') for toxic pollutants in the Delaware Estuary (DRBC Water Quality Zones 2 through 5) and extended application of the criteria to Delaware Bay (DRBC Water Quality Zone 6).

Effective Date:

Upon publication in the Pennsylvania Bulletin. The rule was incorporated by reference into the Code of Federal Regulations effective March 23, 2011.

Supplemental Information:

The Delaware River Basin Commission is a federal-state regional agency charged with managing the water resources of the Delaware River Basin without regard to political boundaries. Its members are the governors of the four basin states—Delaware, New Jersey, New York, and Pennsylvania—and the North Atlantic Division Commander of the U.S. Army Corps of Engineers, representing the federal government.

Notice of the proposed amendments appeared in the Pennsylvania Bulletin (40 Pa.B. 4278) on July 31, 2010, as well as in the Federal Register (75 FR 41106) on July 15, 2010, the Delaware Register of Regulations (14 DE Reg. 70-83 (08/01/2010)) on August 1, 2010, the New Jersey Register (42 N.J.R. 1702(a)) on August 4, 2010, and the New York State Register (p. 6) on July 21, 2010. A public hearing was held on September 23, 2010 and written comments were accepted through October 1, 2010. The commission received two written submissions and no oral testimony on the proposed changes. The Commission made minor revisions to the proposed amendments in response to the comments received. A comment and response document setting forth the Commission's responses and revisions in detail was approved by the Commission simultaneously with adoption of the final rule.

Resolution No. 2010-13, the text of the final rule, a copy of the comment and response document, and a basis and background document published simultaneously with the proposed rule are available on the Commission's web site, at http://www.state.nj.us/drbc/toxics_info.htm.

Rule Text:

DRBC Resolution No. 2010-13 amends Article 3 of the Water Code and Article 3 of the Administrative Manual—Part III Water Quality Regulations as set forth below. Additions are printed in BOLD FACE and deletions are printed in [BOLD FACE ENCLOSED IN BRACKETS]. BOLD FACE UNDERSCORE indicates changes made in response to comments received during the public comment period. Asterisks indicate ellipsis of rule text retained without changes.

Section 3.10.3 Stream Quality Objectives

* * * * *

C. Aquatic Life Objectives for Toxic Pollutants. It is the policy of the Commission to designate numerical stream quality objectives for the protection of aquatic life for the Delaware River Estuary and Bay (Zones 2 through 6 [5]) which correspond to the designated uses of each zone. Aquatic life objectives for the protection from both acute and chronic effects are herein established on a pollutant-specific basis for:

* * * * *

D. Human Health Objectives for Toxic Pollutants. It is the policy of the Commission to designate numerical stream quality objectives for the protection of human health for the Delaware River Estuary and Bay (Zones 2 through 6 [5]) which correspond to the designated uses of each zone. Stream quality objectives for protection from both carcinogenic and systemic effects are herein established on a pollutant-specific basis for:

* * * * *

3.10.3.D.6. A rate of ingestion of water of 2.0 liters per day is assumed in calculating objectives for river zones where the designated uses include public water supplies after reasonable treatment. A rate of ingestion of fish of [6.5] 17.5 grams per day (equivalent to consuming a 1/2 pound portion every [35] 13 days) is assumed in calculating freshwater and marine stream quality objectives for the protection of human health. [A rate of ingestion of fish of 37 grams per day (equivalent to consuming a 1/2 pound portion every 6 days) is assumed in calculating marine stream quality objectives for human health.]

3.10.3.D.8. Numerical criteria for toxic pollutants to protect the taste and odor of ingested water and fish shall be applied as stream quality objectives in [the Estuary] Zones 2—6 if these criteria are more stringent than the calculated human health objectives for carcinogens or systemic toxicants.
