24 For Immediate Release December 18, 2001 DROUGHT EMERGENCY DECLARED IN THE DELAWARE RIVER BASIN (WEST TRENTON, N.J.) - With reservoir storage and ground water supplies well below seasonable averages, the Delaware River Basin Commission (DRBC) today declared a drought emergency in the 13,539 square-mile watershed which drains portions of New York State, Pennsylvania, New Jersey, and Delaware.
25
25 DEP Drought Coordination DEP coordinates with the Delaware River Basin Commission (DRBC) and the Susquehanna River Basin Commission (SRBC)- interstate-federal agencies responsible for managing the water resources within the Delaware and Susquehanna River watersheds

26 How Bad is It? ’98-’99 vs ’01-’02
27
27 ’98-’99 Drought (in current drought warning area) We entered the summer of ’98 with normal to above normal stream and well levels Precipitation dropped off from July ’98 through December ’98 Significant precipitation occurred statewide in January ’99. It took two hurricanes (Dennis and Floyd) in September ’99 to raise stream and well levels We entered the summer of ’98 with normal to above normal stream and well levels Precipitation dropped off from July ’98 through December ’98 Significant precipitation occurred statewide in January ’99. It took two hurricanes (Dennis and Floyd) in September ’99 to raise stream and well levels
28
28 ’01-’02 (in current drought warning area) We have had below normal precipitation since October 2000 Groundwater and stream levels have been below normal since about June Gages currently show below normal precipitation, stream and well levels in a season with frozen ground conditions and lower recharge potential We have had below normal precipitation since October 2000 Groundwater and stream levels have been below normal since about June Gages currently show below normal precipitation, stream and well levels in a season with frozen ground conditions and lower recharge potential

35 CHAPTER 118. REDUCTIONS OF MAJOR WATER USE IN A COMMONWEALTH DROUGHT EMERGENCY AREA CHAPTER 119. PROHIBITION OF NONESSENTIAL WATER USES IN A COMMONWEALTH DROUGHT EMERGENCY AREA CHAPTER 120. LOCAL WATER RATIONING PLANS
36
36 Chapter 118 Provides for preparation and implementation of drought contingency plans by: –Public water supplies (>50 connections) –Major commercial water users –Major industrial water users Provides for preparation and implementation of drought contingency plans by: –Public water supplies (>50 connections) –Major commercial water users –Major industrial water users
37
37 Drought Contingency Plan Submission Any time As directed by Governor’s emergency proclamation As ordered by Commonwealth Drought Coordinator (CDC) Any time As directed by Governor’s emergency proclamation As ordered by Commonwealth Drought Coordinator (CDC)
38
38 Public Water Supply Drought Contingency Plan Elements: Analysis of water availability and water use over the last 12 month period Description of trigger levels Plan of action Variance procedures Desirable to have plan implemented at all times Analysis of water availability and water use over the last 12 month period Description of trigger levels Plan of action Variance procedures Desirable to have plan implemented at all times
39

44 County Drought Management Task Force Established by County Commissioners within time frame specified in Governor’s Emergency Proclamation Coordinates and monitors all drought reporting and water conservation measures undertaken in the county Reports monthly to CDC Established by County Commissioners within time frame specified in Governor’s Emergency Proclamation Coordinates and monitors all drought reporting and water conservation measures undertaken in the county Reports monthly to CDC
45
45 Chapter 119 Restricts non-essential water uses in response to a drought or water shortage emergency declared by the Governor
46
46 Prohibition of Non-essential Water Uses Watering grass Athletic fields (except under approved plan) Gardens and Landscaping Golf Courses (except under approved plan) Watering grass Athletic fields (except under approved plan) Gardens and Landscaping Golf Courses (except under approved plan) Paved surfaces Ornamental uses Mobile equipment Serving in restaurants (unless requested) Swimming pools Specific fire hydrant uses Use of any water not for a beneficial use Paved surfaces Ornamental uses Mobile equipment Serving in restaurants (unless requested) Swimming pools Specific fire hydrant uses Use of any water not for a beneficial use
47
47 Exceptions Each prohibition has associated limited exceptions listed in Chapter 119 (for example-watering athletic fields is allowable under an approved plan).
48
48 Exemptions and Variances Water user must demonstrate extraordinary hardship Public water suppliers must demonstrate adequate water supply and follow an approved drought contingency plan Water user must demonstrate extraordinary hardship Public water suppliers must demonstrate adequate water supply and follow an approved drought contingency plan
49
49 Exemptions and Variances CDC makes a decision within 7 working days (one day if perishable products are involved) Areawide exemptions or variances for similar situated water users possible Decisions may be appealed to PEMA CDC makes a decision within 7 working days (one day if perishable products are involved) Areawide exemptions or variances for similar situated water users possible Decisions may be appealed to PEMA
50
50 Chapter 120 Establishes procedures for the CDC to review and approve local water rationing plans in response to severe local water shortages. Such plans can be approved only under the authority of a declared emergency.
51
51 Typical Water Rationing Plan Content Prohibition of non-essential water use Equitable rationing provisions (% reduction, or assigned customer allocations) Variance and exemption provisions to address extraordinary hardships Prohibition of non-essential water use Equitable rationing provisions (% reduction, or assigned customer allocations) Variance and exemption provisions to address extraordinary hardships
52
52 Implementation of Local Water Rationing Plan By application to the CDC, who must approve the local rationing plan At the direction of the CDC By application to the CDC, who must approve the local rationing plan At the direction of the CDC
53
53 Additional Water Rationing Provisions Enforced at the local level Service interruptions are authorized Excess use charges are authorized –Maximum of 5 times the actual rate for first 2,000 gallons and 10 times actual rate for each 1,000 gallons or portion thereof Enforced at the local level Service interruptions are authorized Excess use charges are authorized –Maximum of 5 times the actual rate for first 2,000 gallons and 10 times actual rate for each 1,000 gallons or portion thereof
54
54 Additional Water Rationing Provisions Customer service interruptions used –Individual flow restrictions and termination of water service to individual customers is authorized Customer service interruptions used –Individual flow restrictions and termination of water service to individual customers is authorized

55 Drought ’02 Will There Be Enough Water for Everyone? We don’t know We need to be prepared
56
56 What Else Is DEP Doing to Manage Water Resources? Supporting passage of Water Resources Conservation and Protection Legislation Proposing a new Comprehensive Stormwater Management Policy Supporting passage of Water Resources Conservation and Protection Legislation Proposing a new Comprehensive Stormwater Management Policy
57
57 Major Elements of Proposed Water Resources Legislation Update State Water Plan Identify Critical Water Planning Areas Encourage locally developed Integrated Water Resource Plans Update State Water Plan Identify Critical Water Planning Areas Encourage locally developed Integrated Water Resource Plans Establish water use reduction and water conservation incentives Establish water well construction requirements Establish water use reduction and water conservation incentives Establish water well construction requirements
58
58 Major Elements of Updated Stormwater Management Policy Encourage infiltration of stormwater Implement federal regulations Achieve administrative efficiencies within DEP Encourage infiltration of stormwater Implement federal regulations Achieve administrative efficiencies within DEP
