(5) The construction of new facilities or alteration or addition to existing facilities for the direct discharge to surface or ground waters of industrial wastewater having design capacity of less than 10,000 gallons per day in the drainage area to Outstanding Basin Waters and Significant Resource Waters or less than 50,000 gallons per day elsewhere in the Basin; except where such wastewater contains toxic concentrations of waste materials;

(6) A change in land cover on major ground water infiltration areas when the amount of land that would be altered is less than three square miles;

(7) Deepening, widening, cleaning or dredging existing stream beds or relocating any channel, and the placement of fill or construction of dikes, on streams within the Basin except the Delaware River and tidal portions of tributaries thereto, and streams draining more than one state;

(8) Periodic maintenance dredging;

(9) Encroachments on streams within the Basin caused by:

(i) Floating docks and anchorages and buoys and navigational aids;

(10) Bridges and highways unless they would pass in or across an existing or proposed reservoir or recreation project area as designated in the Comprehensive Plan;

(11) Liquid petroleum products pipelines and appurtenances designed to operate under pressures less than 150 psi; local electric distribution lines and appurtenances; local communication lines and appurtenances; local natural and manufactured gas distribution lines and appurtenances; local water distribution lines and appurtenances; and local sanitary sewer mains, unless such lines would involve significant disturbance of ground cover affecting water resources;

(12) Electric transmission or bulk power system lines and appurtenances; major trunk communication lines and appurtenances; natural and manufactured gas transmission lines and appurtenances; major water transmission lines and appurtenances; unless they would pass in, on, under or across an existing or proposed reservoir or recreation project area as designated in the Comprehensive Plan; unless such lines would involve significant disturbance of ground cover affecting water resources;

(13) Liquid petroleum products pipelines and appurtenances designed to operate under pressures of more than 150 psi, unless they would pass in, on, under or across an existing or proposed reservoir or recreation project area as designated in the Comprehensive Plan, or in, on, under or across any stream within the Basin; unless such lines would involve significant disturbance of ground cover affecting water resources;

(14) Landfill projects, unless no state-level review and permit system is in effect; broad regional consequences are anticipated; or the standards or criteria used in state level review are not adequate to protect the water of the Basin for the purposes prescribed in the Comprehensive Plan;

(15) Draining, filling or otherwise altering marshes or wetlands when the area affected is less than 25 acres; provided; however, that areas less than 25 acres shall be subject to Commission review and action;

(i) Where neither a state nor a federal level review and permit system is in effect, and the Executive Director determines that a project is of major regional or interstate significance requiring action by the Commission, or

(ii) When a Commissioner or the Executive Director determines that the final action of a state or federal permitting agency may not adequately reflect the Commission's policy as to wetlands of the Basin. In the case of a project affecting less than 25 acres for which there has been issued a state or federal permit, a determination to undertake review and action by the Commission shall be made no later than 30 days following notification of the Commission of such permit action. The Executive Director, with the approval of the Chairman, may at any time within the 30-day period inform any permit holder, signatory party or other interested party that the Commission will decline to undertake review and action concerning any such project;

(16) The diversion or transfer of water from the Delaware River Basin (exportation) whenever the design capacity is less than a daily average rate of 100,000 gallons;

(17) The diversion or transfer of water into the Delaware River Basin (importation) whenever the design capacity is less than a daily average rate of 100,000 gallons except when the imported water is wastewater;

(18) The diversion or transfer of wastewater into the Delaware River Basin (importation) whenever the design capacity is less than a daily average rate of 50,000 gallons; and

(19) Temporary or short term projects determined to have non-substantial impact on the water resources of the Basin by the Executive Director.

(b) All other projects which have or may have a substantial effect on the water resources of the Basin shall be submitted to the Commission in accordance with this part for determination as to whether the project impairs or conflicts with the Comprehensive Plan. Among these are projects involving the following (except as provided in paragraph (a) of this section):

(1) Impoundment of water;

(2) Withdrawal of ground water;

(3) Withdrawal of water from impoundment or streams;

(4) Diversion of water into or out of the Basin;

(5) Deepening or widening of existing stream beds, channels, anchorages, harbors or tuning basins, or the construction of new or enlarged channels, anchorages, harbors or turning basins, or the dredging of the bed of any stream or lake and disposal of the dredged spoil, when the nature or location of the project would affect the quantity or quality of ground or surface waters, or fish and wildlife habitat;

(6) Discharge of pollutants into surface or ground waters of the Basin;

(7) Facilities designed to intercept and transport sewage to a common point of discharge; and pipelines and electric power and communication lines;

(8) Facilities for the direct discharge to surface or ground waters of industrial wastewater;

(9) Projects that substantially encroach upon the stream or upon the 100-year flood plain of the Delaware River or its tributaries;

(10) Change in land cover on major ground water infiltration areas;

(11) Hydroelectric power projects, including pumped storage projects;

(12) Projects or facilities of Federal, state and local agencies such as highways, buildings and other public works and improvements, affecting the water and related land resources of the Basin;
