Fast Facts:Delaware River Main stem river is 330 miles long

Delaware River forms an interstate boundary over its entire length

13+ million people (about 5% of the U.S. population) rely on the waters of the Delaware River Basin

Drains 13,539 square miles in 4 states.

Water withdrawal in the Basin = 6.6 billion gallons/day

Significant Exports: NYC (up to 800 MGD) and NJ (up to 100 MGD)

Longest, un-dammed U.S. river east of the Mississippi (dams are located on tributaries, not the main stem Delaware)

Contributes over $21B in economic value to the region.

“A river is more than an amenity, it is a treasure”-US Supreme Court Justice

Oliver Wendell Holmes

We are here.

What is an interstate compact?

▪ An arrangement between two of more states that is designed to solves their common problems and that becomes part of the laws of each state.

▪ Under Article 1, Section 10, Clause 3 of the US Constitution states: “No state shall, without the Consent of Congress…enter into any Agreement of Compact with any other State”.

Five Equal Members:

▪ Delaware

▪ New Jersey

▪ Pennsylvania

▪ New York

▪ Federal Government

Who is DRBC? - Delaware River Basin CommissionFounded by Compact in 1961

Note: New York City and Philadelphia are “advisors” and not members

Lawyers Communications Support

Why was the DRBC created?

• Water supply shortages and disputes over the apportionment of the basin’s waters;

• Severe pollution in the Delaware River and its major tributaries;

• Serious flooding

1937

To address the Need for Basin-Scale Planning and Management

▪ 4 States

▪ 42 Counties

▪ 838 Municipalities

▪ New York City

Why was the DRBC created?

Question: How many students grew up within the Delaware River Basin?

~ 9 Million NYC residents rely for the DRB for ~ %50 of their water

• 1921: New York City Board of Water Supply investigates additional sources to supplement Catskill system

• 1920’s: Unsuccessful efforts to reach interstate agreement

• 1929: New Jersey petitions U.S. Supreme Court to enjoin NYC and NYS from constructing DRB reservoir

• 1931 Supreme Court Decree

Why was DRBC created? Interstate Water Disputes

What does DRBC do? Primary Functional Responsibilities

• Water Supply

• Drought Management

• Flood Loss Reduction

• Water Quality

• Watershed Planning

• Regulatory Review (Permitting)

• Outreach/Education

• Recreation

Quantity – An adequate and sustainable supply of water.

Quality – Clean and healthy water resources.

Essentially “Quantity” and “Quality”

• Public drinking water (after reasonable treatment)

• Recreation

• Wildlife, fish and other aquatic life

• Regulated waste assimilation

Water Quality – Establish “Uses”

Water Quality – Set Standards

❑From 1962, Commission adopted Water Quality Regulations pursuant to Article 5 of the Compact;

❑To protect aquatic life and human health for both carcinogenic and non-carcinogenic effects.

❑Updated and revised periodically to the present;

❑ Includes standards for mainstem Water Quality Management Zones, interstate tributaries, and some basin wide standards.

Water Quality - Monitoring

1) Fish Tissue

2) Ambient Water

3) Sediment

4) Atmosphere

5) Point Sources

Water Quality - Assessments

How do we do it?

1. Regulatory Agency DRBC issues dockets (approvals) for projects that impact water resources

Discharges : effluent limitations Withdrawals : quantity restrictions / temporal restrictions Reservoirs : minimum releases / operating plans

Establish ambient water quality standards

2. Planning Agency Long term water supply planning Reservoir and river flow modeling Water quality modeling – dockets, TMDLs, etc.

3. Monitoring & Assessment Measure and assess water, sediment, biota Martins Creek Power Plant. Credit: DRBC

How do we do it? Significant Regulatory Programs

DRB Compact Section 3.8:

• No project having a substantial effect on the water resources of the Basin shall…be undertaken…unless it …[is] submitted to and approved by the Commission.

• The Commission shall approve a project whenever it finds…that such a project will not substantially impair or conflict with the comprehensive plan…

• Typical regulatory programs:

•Water withdrawals

•Wastewater treatment/discharges

•Flood Plain

•Other projects Groundwater withdrawal. Credit: DRBC

How do we do it? DRBC Advisory Committees

▪ Flood

▪ Regulated Flow

▪ Water Management

▪ Toxics

▪ Water Quality

▪ Monitoring Advisory & Coordination

How do we do it? - Planning

➢ Compact – Planning Powers and Duties (Section 3.2)

➢ Comprehensive Plan (Section 13.1)

>Water Resources Program (Section 13.2)

Compact : Article 4 Water Supply

4.1 Generally. The commission shall have power to develop, implement and effectuate plans and projects for the use of the water of the basin for domestic, municipal, agricultural and industrial water supply. To this end,

without limitation thereto, it may provide for, construct, acquire, operate and maintain dams, reservoirs and other facilities for utilization of surface and ground water resources, and all related structures, appurtenances and equipment on the river and its tributaries and at such off-river sites as it may find appropriate, and may regulate and control the use thereof.

• Specific projects and facilities and statements of policy and programs may be incorporated, deleted or modified to reflect changing conditions, research and new technology.

• Versions

✓ 1st CP – March 28, 1962; approved by Resolution 62-4. 21 (proposed) Reservoir/Storage Projects.

✓ 2nd CP (draft) – September 1973 – Never adopted via Resolution (reliance upon Tocks Island).

✓ 3rd CP – July 2001, adopted by Resolution No. 2001-27.

• Resolution No. 2001-27 recognized an ongoing “Comprehensive Plan” related effort by the Watershed Advisory Council (1999-2004). That effort ultimately resulted in goal-based plan (vs. an updated CP).

How do we do it? - Comprehensive Plan

• WRP required by the Compact (Articles 3.2 & 13.2)

• Required to be updated annually, sets strategic plan for DRBC program direction “during the ensuing six years or such other reasonably foreseeable period” (lately 3 years)

• Program presented in two parts:

- Section I - Conditions

- Section II – Work Program

• FY2019-2021 recently approved
