Project scope of work summary:

The purpose of this project is to allow continued access for recreational boaters and emergency services as water levels in Lake Mead drop. This project will utilize Nationwide Permit 36 (Boat Ramps) to extend an existing launch ramp by 529 feet (horizontal distance perpendicular to the water’s edge) at Hemenway Harbor in Boulder City, Clark County, Nevada. The ramp will extend from 1,027 feet above mean sea level to an elevation of approximately 997 feet above mean sea level. The ramp extension will be 100 feet wide and will also include riprap installed around the perimeter of the ramp extension. Construction elements will include the following: installation of temporary erosion and sediment control measures (including turbidity curtain), removal and salvage of existing pipe mats, excavation of soft lakebed sediment, grading, placement of an aggregate base and riprap, installation of pre-cast concrete panels, and the installation of a riprap perimeter trench. Discharges will consist of base materials (aggregate and riprap) and precast concrete panels. A turbidity curtain will be installed and maintained to contain sediment that will be disturbed and suspended during construction activities.

For work in relatively shallow water (generally, less than 10 feet deep), the excavator will be positioned on the launch ramp upslope of the work area. Tracked equipment will not be allowed to operate in water deep enough to submerge the top of the tracks. For work in deeper water (up to 40 feet deep), the excavator will be positioned on a barge temporarily moored offshore. Excavated lakebed sediments will be temporarily stockpiled and decanted in an upland position prior to being hauled offsite and disposed of at an approved upland facility. A long-reach excavator will be used to install the pre-cast panels. Project construction is anticipated to start in October 2024 and is expected to be completed within two years.

A detailed project description, including measures to ensure that discharges to waters of the U.S. do not significantly impact water quality, is included in the Certification Request and in additional information attached to the Certification

Request.

1 Permits and Licenses All other required federal and State permits or licenses must be obtained prior to construction commencement to ensure compliance with all federal and State regulations (NRS 445A.300 - 445A.730; NAC 445A.228).

Water Quality

Standards/Beneficial Uses

Any discharge associated with the proposed activity shall not exceed State water quality standards or impair the beneficial uses of any water of the State. Beneficial uses define the water quality criteria required to protect the uses of a waterbody and exceedances are a violation of State regulation. No exceedances of water quality standards or impairment of beneficial uses of the waterbody are permitted (NRS

445A.520; NRS445A.720; NAC 445A.118 - 445A.2234).

901 S. Stewart Street, Suite 4001 • Carson City, Nevada 89701 • p: 775.687.4670 • f: 775.687.5856 • ndep.nv.gov

3 High Quality Waters

Any surface waters of the State whose quality is higher than the applicable water quality standards, as of the date when those standards become effective, must be maintained in their higher quality. No discharges of a pollutant may be made which will result in lowering the quality of these waters (NRS 445A.565).

Waters with Approved

TMDLs and 303(d) Listed Waters

If the proposed project would discharge into a waterbody listed as impaired and on the current 303(d) list or has an approved TMDL, no discharges of a pollutant may be made which will result in further degradation of these waters without approval by NDEP. For the most current list of approved TMDLs for Nevada, please refer to NDEP’s Water Quality Integrated Report (https://ndep.nv.gov/uploads/water-wqm-docs/IR2022FINAL_Report.pdf). Waters listed as impaired or with approved TMDLs are not meeting the requirements for their designated beneficial uses. NDEP requires review to ensure the proposed project will not exceed numeric or narrative water quality criteria for the waterbody and that BMPs for the project adhere to suggested BMPs outlined in applicable TMDLs (NRS 445A.520; NRS 445A.720; NAC 445A.228).

Best Management Practices

(BMPs)

Work in or adjacent to waters of the State shall be performed in such a way that minimizes discharges of pollutants to the receiving waterbody. Best Management Practices to control and mitigate inputs of pollutants must be implemented and functional prior to commencement of work and shall be maintained and modified throughout the duration of work performed to assure that State water quality standards are met. Pollutants are defined as artificially made or induced alterations to the physical, chemical, or biological integrity of the water (NRS 445A.525; NAC 445A.121).

6 Equipment Use

a. Equipment used during project implementation must be in proper working condition and free from leaks to prevent discharge of debris, oil, grease, scum, and other floating materials to waters of the State which could have adverse effects on the chemical, physical, or biological function of the waterbody (NAC 445A.121).

b. Equipment fueling, staging, maintenance, and repair must be conducted in an upland position where discharge of pollutants, incidental to these activities, do not have the potential to pollute waters of the State (NAC 445A.121).

c. Equipment operation shall be conducted in a manner that minimizes impacts to waters of the State (NAC 445A.121).

Construction

Except those authorized by this Certification, no pollutants associated with this project shall be discharged or allowed to remain in a position where a pollutant can be carried to waters of the State by any means. Material permitted to enter waters of the State must be stabilized in a position to prevent excessive erosion. Pollutants are defined as artificially made or induced alterations to the physical, chemical, or biological integrity of the water. Pollutants can include, but are not limited to soil, sand, silt, rock, dredge material, chemical waste, biological material, heat, concrete, concrete washings, and discarded equipment (NRS 445A.400; NRS 445A.465).

8 Concrete

Wet and uncured concrete shall not be allowed to enter waters of the State.

Impermeable covers must be placed over concrete not poured into forms to prevent degradation of waters of the State through seepage and leaching of uncured concrete

(NRS 445A.465).

Invasive Species

Management

Equipment and materials must be free from invasive species that could be discharged or carried into the waters of the State by any means. If BMPs incorporate natural materials, such as seeds, mulch, straw bales, or coir logs, they shall be certified as weed free. Equipment and materials must be free from invasive species to protect the physical, chemical, and biological integrity of waters of the State and to prevent the spread of invasive species throughout the State (NRS 445A.465; NRS 555.010; NRS 555.150).

Revegetation and Site

Restoration

Disturbance of existing vegetation shall not exceed the minimum necessary to complete the project. If revegetation is proposed to restore and stabilize areas affected during construction, site-appropriate plant materials shall be used with an emphasis on native and/or adapted perennial vegetation. Site stabilization is

901 S. Stewart Street, Suite 4001 • Carson City, Nevada 89701 • p: 775.687.4670 • f: 775.687.5856 • ndep.nv.gov necessary to prevent erosion, decrease sediment inputs into waters of the State, and reduce encroachment of invasive species in denuded areas since invasive species are associated with modified hydrologic regimes and deleterious impacts to the aquatic environment (NRS 445A.305).

Post-Construction

Upon completion of the project, affected areas must be returned to pre-construction elevations and contours. All temporary and excess materials and installments used during construction must be removed from the site to prevent pollutants from entering waters of the State by any means (NRS 445A.465).

12 Post-Project Reporting

Following project completion, the project proponent shall send NDEP digital color photographs (jpg/jpeg preferred) that are representative of waters impacted by the activity. Photos must include BMPs used to prevent erosion, control sediment, and protect water quality. Before, during, and after photos should be taken from a consistent photo point in the same direction using the same zoom and aspect. Major linear utility projects may provide representative photos of only the most sensitive sites (e.g., wetlands or channel crossings). Post-project reporting is necessary to ensure project BMPs were installed as proposed (NRS 445A.530).

C. Special Conditions

Condition Number

Condition Title Condition Description and Reference to Federal and/or State Water Quality Requirement(s)

13 Turbidity Curtain

Excavation within the aquatic feature will disturb lake bottom sediments leading to turbidity impacts within the adjacent water column. Turbidity curtains have been proposed as temporary BMPs during project implementation. Contractor-grade turbidity curtains shall be free from aquatic invasive species and properly installed, per manufacturer’s specifications, around the anticipated area of impact during construction activities. The turbidity curtains shall remain in place and maintained until suspended sediment has settled and turbidity levels meet water quality standards for Lake Mead. Additional precautions should be taken during inclement weather and high winds to prevent failure of turbidity curtains. This condition is necessary to prevent turbidity impacts in the adjacent water column during project implementation (NRS 445A.720; NRS 445A.530; NRS 445A.525; NAC 445A.2152; NAC 445A.121).

14 Decant Return Flows

Decanting dredged spoils in an upland position is proposed during grading activities.

Decanted water may contain elevated levels of suspended sediments posing an increased risk of turbidity impacts to waters of the U.S. The discharge of return flows that would result in an exceedance of water quality standards, including the turbidity standard, for Lake Mead is not authorized. To minimize water quality impacts during dredging operations, return flows of decant water from dredged material shall be prevented from being discharged into any water of the U.S. that would result in an exceedance of water quality requirements and standards (NRS 445A.720; NRS

445A.530; NRS 445A.525; NAC 445A.2152; NAC 445A.121).

D. Condition Statements of Necessity

The conditions above ensure compliance with applicable water quality requirements, minimization of individual and cumulative adverse effects on the aquatic environment, and the continued use and enjoyment of Nevada’s water resources for future generations (NRS 445A.720). The State has an obligation to protect the beneficial uses of waterbodies across its jurisdiction through the development of water quality standards and criteria (NRS 445A.530; NAC 445A.118 - 445A.2234). Projects which require a federal license or permit must first receive certification from the state in which the discharge originates, or will originate, to verify that any proposed activity complies with federal, State, and local regulation (40 CFR §121; NRS 445A.620; NRS 445A.720). The conditions above have been developed for the proposed project because

901 S. Stewart Street, Suite 4001 • Carson City, Nevada 89701 • p: 775.687.4670 • f: 775.687.5856 • ndep.nv.gov these activities have been determined to have an increased potential to pollute waters of the State and steps must be taken to ensure compliance with applicable water quality requirements (NRS 445A.525; NRS 445A.565). The State must develop limitations necessary to meet water quality standards, treatment standards, and schedules of compliance established pursuant to the laws of this State and any other federal law or regulation and is required to implement any applicable water quality standard established pursuant to NRS 445A.300 to 445A.730, inclusive, such limitations shall be established (NRS 445A.530; NAC 445A.118 - 445A.2234).

Pursuant to 40 CFR §121.7(d)(3), narrative statements justifying the conditions listed by number follows below:

1. Water Quality Certification does not negate the requirement for applicants to obtain all other required federal, State, and local permits, licenses, and authorizations prior to construction commencement which ensures compliance with all applicable water quality-related requirements (NRS 445A.300 - 445A.730; NAC 445A.228).

2. To protect Nevada’s water resources, any discharge associated with a project occurring in waters of the State shall not exceed State water quality standards or impair the beneficial uses for the applicable waterbody (NRS 445A.520). Beneficial uses define the water quality criteria required to support the existing uses of a waterbody and exceedances are a violation of State law. To prevent the proposed activities from interfering with attainment of applicable beneficial uses no exceedances of water quality standards or impairment of beneficial uses of the waterbody are permitted (NRS 445A.520; NRS 445A.720; NAC 445A.118 - 445A.2234).

3. To protect the continued attainment of high-quality waterbodies, no discharges of a pollutant from a point source may be made which will result in lowering the quality of these waters. NDEP requires review to ensure the proposed project will not exceed applicable numeric or narrative water quality standards for the waterbody and that BMPs promote the chemical, physical, and biological integrity of these waters (NRS 445A.565; NRS 445A.720;

NAC 445A.228).

4. To prevent further degradation of 303(d) listed waterbodies and waterbodies with an approved TMDL, no discharges of a pollutant from a point source may be made which will result in further degradation of these waters.

For the most current list of approved TMDLs for Nevada, please refer to NDEP’s Water Quality Integrated Report (https://ndep.nv.gov/uploads/water-wqm-docs/IR2022FINAL_Report.pdf). NDEP requires review to ensure the proposed project will not exceed applicable numeric or narrative water quality standards for the waterbody and that BMPs promote the chemical, physical, and biological integrity of these waters (NRS 445A.720; NAC 445A.228).

5. Best Management Practices are effective measures to control and mitigate point source inputs of pollutants into a waterbody. Prior to commencement of any work in waters of the State, BMPs designed for the project must be in place and shall be maintained throughout the duration of the project to ensure no more than minimal effects to the aquatic environment (NRS 445A.525; NAC 445A.121). A list of BMPs recommended by NDEP are available on the BWQP website: https://ndep.nv.gov/water/rivers-streams-lakes/nonpoint-source-pollution-management-program/best-management-practices-toolbox.

6. Equipment used in waters of the State must be in proper working condition and free from leaks. Any maintenance, repair, or staging of this equipment must be completed in an upland position to prevent discharge of debris, oil, grease, scum, and other floating materials to waters of the State which could have adverse effects on the aquatic environment (NRS 445A.520; NAC 445A.121.2).

7. Except those authorized by this Certification, no pollutants associated with this project will be discharged from a point source or allowed to remain in a position where a pollutant can be carried to waters of the State by any means and material permitted to enter waters of the State must be stabilized in a way that prevents excessive erosion. Adherence to this condition prevents violations of water quality standards and State law (NRS 445A.400).

901 S. Stewart Street, Suite 4001 • Carson City, Nevada 89701 • p: 775.687.4670 • f: 775.687.5856 • ndep.nv.gov

8. Wet and uncured concrete negatively impacts the chemical and physical integrity of water if allowed to enter a waterbody and poses a serious hazard to aquatic life. No wet or uncured concrete shall be allowed to enter waters of the State by any means. Impermeable covers shall be placed over any wet or uncured concrete to prevent leaching of this pollutant into a waterbody (NRS 445A.465).

9. Equipment and materials must be free from invasive species that could be discharged or carried into the waters of the State by any means. If BMPs incorporate natural materials, such as seeds, mulch, straw bales, or coir logs, they shall be certified as weed free. Equipment and materials must be free from invasive species to protect the physical, chemical, and biological integrity of waters of the State and to prevent the spread of invasive species throughout the State (NRS 445A.465; NRS 555.010; NRS 555.150).

10. Disturbance of existing vegetation shall not exceed the minimum necessary to complete the project. If revegetation is proposed to restore and stabilize areas affected during construction, site-appropriate plant materials shall be used with an emphasis on native and/or adapted perennial vegetation. Site stabilization is necessary to prevent erosion, decrease sediment inputs into waters of the State, and reduce encroachment of invasive species in denuded areas since invasive species are associated with modified hydrologic regimes and deleterious impacts to the aquatic environment (NRS 445A.305).

11. All temporary and excess materials and installments used during construction shall be removed from the site upon project completion to prevent pollutants from entering waters of the State by any means. Affected areas must be returned to pre-construction elevations and contours to prevent unauthorized alterations to a waterbody once a project is complete (NRS 445A.465).

12. Following project completion, the project proponent shall send NDEP digital color photographs (jpg/jpeg preferred) that are representative of waters impacted by the activity. Photos must include BMPs used to prevent erosion, control sediment, and protect water quality. Before, during, and after photos should be taken from a consistent photo point in the same direction using the same zoom and aspect. Major linear utility projects may provide representative photos of only the most sensitive sites (e.g., wetlands or channel crossings). Post-project reporting is necessary to ensure project BMPs were installed as proposed (NRS 445A.530).

Excavation within the aquatic feature will disturb lake bottom sediments leading to turbidity impacts within the adjacent water column. Turbidity curtains have been proposed as temporary BMPs during project implementation. Contractor-grade turbidity curtains shall be free from aquatic invasive species and properly installed, per manufacturer’s specifications, around the anticipated area of impact during construction activities.

The turbidity curtains shall remain in place and maintained until suspended sediment has settled and turbidity levels meet water quality standards for Lake Mead. Additional precautions should be taken during inclement weather and high winds to prevent failure of turbidity curtains. This condition is necessary to prevent turbidity impacts in the adjacent water column during project implementation (NRS 445A.720; NRS 445A.530; NRS

445A.525; NAC 445A.2152; NAC 445A.121).

13. Decanting dredged spoils in an upland position is proposed during grading activities. Decanted water may contain elevated levels of suspended sediments posing an increased risk of turbidity impacts to waters of the U.S. The discharge of return flows that would result in an exceedance of water quality standards, including the turbidity standard, for Lake Mead is not authorized. To minimize water quality impacts during dredging operations, return flows of decant water from dredged material shall be prevented from being discharged into any water of the U.S.

that would result in an exceedance of water quality requirements and standards (NRS 445A.720; NRS 445A.530;

NRS 445A.525; NAC 445A.2152; NAC 445A.121).
