2022-0034121-S7

Hi Rhys, We are responding to your notification sent via electronic mail on April 20, 2022, regarding culvert inspection and clearing on North Vandenberg Space Force Base within the main cantonment area. The proposed project would include the inspection of 364 culverts using high-powered flashlights and clearing of culverts using a vacuum truck. Once clear of debris, a remotely operated vehicle would take 360-degree images of each culvert to determine the scope of maintenance needed. The total linear distance for all culverts proposed for clearing and inspection is 11.3 kilometers. The proposed project would occur in the late summer of 2022 during daylight hours and the Space Force expects minimal ground disturbance. The inspections would result in recommendations for future work which the Space Force would present to the Service as needed prior to any future repair work.

Under the Terms and Conditions of the Programmatic Biological Opinion, Vandenberg Air Force Base, Santa Barbara County, California (8-8-13-F-49R), you are required to notify us of project activities that may adversely affect any federally listed species analyzed within this programmatic biological opinion (PBO). You have determined that this project is likely to adversely affect the federally threatened California red-legged frog (Rana draytonii) and vernal pool fairy shrimp (Branchinecta lynchi). The PBO described projects of this nature under section 2.2 Utility Installation, Maintenance, and Removal (Wastewater Lines), pages 19, 21–

22. It described the effects of these project activities to California red-legged frog on pages 116–117; however, the PBO does not address effects of this type of project to vernal pool fairy shrimp but does discuss projects we consider similar on pages 104–106.

Your notification states that no recent or project specific surveys for amphibians have occurred in the area, but that the culverts may provide suitable refuge for California red-legged frog. Biologists recorded the nearest known California red-legged frog location in 2007 approximately 477 meters southwest of the nearest culvert proposed for clearing; however, this area has no roads, and the project proposes no work or staging within 300 meters of this observation point. Prior to initiating work, a Service-approved biologist would inspect all culverts for California red-legged frogs. The project proponent would use a vacuum truck to pump water into each culvert for the purposes of clearing. Water volume would begin low and increase as needed to clear the culvert of soil, vegetation, and debris. A Service-approved biologist would also monitor the outflow for California red-legged frog and would capture and mailto:christopher_diel@fws.gov mailto:rhys.evans@spaceforce.mil mailto:samantha.kaisersatt@spaceforce.mil mailto:darryl.york@spaceforce.mil mailto:erin_arnold@fws.gov mailto:sarah_termondt@fws.gov relocate, as necessary. This project would only occur after the beginning of the non-breeding season for California red-legged frog (after April 15) and would take approximately 16 weeks.

Approximately one week after clearing the culverts, the remotely operated vehicle would take 360-degree images of each culvert determining the scope of maintenance needed.

Your notification further states that the Space Force surveyed pools within the project area for vernal pool fairy shrimp in 2006 and determined only thirteen pools in the southeast corner of the project area were either occupied or suitable but not known to be occupied habitat; the remaining pools were unsuitable habitat. In some instances, occupied pools are directly adjacent to culverts proposed for clearing. The project proponent would not be authorized to allow the flow of significant water into any pool and work will only occur in the dry season when the soil is dry to the touch. If accidental flooding does occur, the project proponent would remove the excess water via the vacuum truck. The Space Force does not expect the hydrology of the project area to change because of the proposed culvert clearing. Although it is unlikely to occur during this project, the PBO does not address accidental flooding of dry vernal pools and its effects on vernal pool fairy shrimp. It also does not address changes in hydrology due to culvert clearing and its effects on vernal pool fairy shrimp. If these events were to occur, we recommend the Space Force contact our office to discuss the need for additional consultation.

Per your notification, the Space Force will implement all other minimization and avoidance measures outlined in sections 7.1 and 7.2 of the PBO, along with the monitoring of water outflow from the vacuum truck, and decontamination of the remotely operated vehicle between drainages. For any project activities conducted within California red-legged frog dispersal distance (43 meters in the dry season, 210 meters in the breeding season), the Space Force will implement California red-legged frog specific avoidance and minimization measures outlined in the reinitiated PBO (2018-F-0664) dated November 20, 2018.

In conclusion, provided the Space Force also implements all appropriate terms and conditions, we agree that the remainder of project activities included in your notification can go forward under the PBO without further consultation. If you have any questions regarding our response to your pre-project notification, please contact Erin Arnold at (805) 677-3343, or by electronic mail at erin_arnold@fws.gov.

7.1 Base-wide Best Management Practices

1. Through the internal project review process at VAFB, 30 CES/CEI biologists will identify projects that meet the scope and intensity of the anticipated work described in this programmatic consultation prior to any project activities commencing.

2. Qualified biologists will conduct pre-activity surveys at each project site for all project activities that may affect the federally listed species analyzed within this biological opinion.

3. Qualified biologists will brief all project personnel prior to participating in activities included in this biological opinion annually or on an as-needed basis. At a minimum, the briefing will include a summary of the proposed actions, a description of the federally listed species that may occur in the project area, and a summary of the measures that the Air Force will implement to avoid or minimize the adverse effects to the federally listed species within a projects’ footprint.

4. Prior to conducting any project activities, a qualified biologist will clearly mark sensitive species habitats within the project site and the immediate area to prevent workers or equipment from adversely affecting species or habitats that are not expected to be damaged during the project.

6. The fueling of vehicles and equipment will occur on impervious surfaces to the maximum extent practicable. Spill containment equipment will be present at all project sites where fuels or other hazardous substances are brought to the site. In addition, qualified personnel will conduct daily inspections of the equipment and the staging and maintenance areas for leaks of hazardous substances.

7. When it is not practical to stage or operate project vehicles or equipment on paved or existing roadways and trails, the Air Force will stage and operate vehicles and equipment on nonnative vegetation to the maximum extent practicable.

8. The Air Force will utilize the most suitable vehicle to minimize erosion potential and will adhere to delineated access routes.

14. The Air Force will implement best management practices (BMPs) that are appropriate to the site and situation to reduce soil erosion, sedimentation, and adverse effects to water quality.

17. Project proponents will clean all equipment and vehicles frequently to reduce the spread of invasive plant species.

18. Project proponents will remove garbage at the end of each day or secure it in an approved container; project spoils will be removed from work sites as often as necessary.

19. The Air Force will cover trenches, holes, and pipeline routes at the conclusion of project activities to avoid the entrapment of animals. If a project lasts for more than 1 day, the Air Force will cover these

7.2 Species-specific Measures

Vernal Pool Fairy Shrimp

2. The Air Force will avoid working within occupied habitat until the soil is dry to the touch.

4. The Air Force will not place or transport fill material into occupied habitats or the designated buffer zones, except potentially during the removal of UXO as part of the MMRP actions to protect military assets.

5. The Air Force will place appropriate sedimentation barriers down-slope of a project site and place construction fencing or other appropriate protective fencing around pools. Fencing will be used in locations where project equipment and (or) personnel is situated adjacent to, or in the near vicinity of, occupied fairy shrimp habitat.

7. When digging is required within occupied habitat during the dry season; the cyst bank will be temporarily removed before the project begins. Using a hand trowel, a one liter sample per pool/swale of the top 1 to 3 centimeters (cm) (0.4 to 1.2 inches) of pool sediment will be collected. Whenever possible, soil samples shall be collected in chunks to best protect the cysts. Soil samples containing any residual moisture initially shall be adequately ventilated and allowed to air dry thoroughly before storage of the sample. The bags containing the soil samples shall be kept out of direct sunlight in order to avoid excessively heating the sample. After the project is completed, the samples will be placed back into the pool.

8. If permanent loss occurs in occupied pools, the pool will be replaced at a 1:1 ratio (habitat enhanced:

habitat affected) with an occupied pool. Cysts from a known occupied pool may be used to seed the new pool’s cyst bank. Narlon Loamy sand may be taken from an area that is not occupied and is outside of the buffer zones. Once the pool is created, the Air Force will monitor it for 3 years to ensure success.

11. No ATVs or carts will be driven in the occupied pools during MMRP activities. When ATVs are used in the buffer zones surrounding occupied habitat, they will be used when the topography is level and will not alter the hydrology of the pools.

California Red-legged Frog

1. When practicable, the Air Force will schedule activities that may affect California redlegged frogs outside of the peak breeding period season (November through March).

7. Equipment maintenance and refueling will be conducted at least 250 feet away from riparian habitats and wetlands.

- Water volume would begin low and increase as needed to clear the culvert of soil, vegetation, and debris.

- Monitor water outflow from vacuum truck

- Decontaminate remotely operated vehicles between drainages

CRLF Measures from Reinitiated PBO (2018-F-0664)

11. Pre-Project Surveys for California red-legged frogs (these apply to implementation of an approved project):

a. From 15 November to 31 March, a Service-approved biologist will conduct a pre-construction survey of project areas within suitable aquatic, adjacent upland, or dispersal habitat (210 meters from aquatic habitat or other distance as determined by a Service-approved biologist following adaptive habitat assessment procedures described in your June 14, 2018, reinitiation request letter (Kephart, in litt. 2018)) immediately before the onset of all work activities.

b. From 1 April to 14 November, the Air Force will conduct a pre-project survey of project areas within suitable aquatic or upland habitat [43 meters from aquatic habitat or other distance as determined by a Service-approved biologist following adaptive habitat assessment procedures described in your June 14, 2018, reinitiation request letter (Kephart, in lilt. 20 18)1 to identify potential artificial water or shelter resources that may contain sheltering California red-legged frogs.

c. The Air Force will repeat surveys following any precipitation event greater than 0.5 centimeter

(0.2 inch) during a 24-hour period.

d. A Service-approved biologist will monitor any initial ground disturbance or vegetation removal within suitable aquatic, adjacent upland, or dispersal habitat identified following the adaptive habitat assessment procedures described in your June 14, 2018, reinitiation request letter (Kephart, in litt. 2018). However, after the initial ground disturbance/vegetation removal is complete, no further monitoring would be required within these bare-dirt areas.

12. Relocation: If California red-legged frogs are found within the project area during pre-project surveys, daily monitoring where required, or at any other time, all construction activity within the vicinity of the California red-legged frog occurrence (if any) will cease and the Air Force will notify the Service immediately. If the project site is large and if the Service-approved biologist is satisfied that work in a different area of the project can continue with no threat to California red-legged frogs, then that work can continue. Construction activities within the vicinity of the California red-legged frog occurrence will not begin or resume until the California red-legged frogs are relocated by a Service-approved biologist or the Service has been contacted and provided alternate guidance.

The Service-approved biologist will relocate all life stages of California red-legged frogs the shortest distance possible to a location that is (1) within the same drainage, (2) contains suitable aquatic/upland habitat, and (3) is outside of the project impact area.

13. Worker Education: Before construction activities begin on a project, a Service-approved biologist will conduct a training session for all construction personnel. At a minimum, the training will include a description of the California red-legged frog and its habitat, the specific measures that are being implemented to conserve the California red-legged frog for the current project, and the boundaries within which the project may be accomplished.

14. Precipitation Events: Construction activities will not occur during or until 24 hours after an actual precipitation event greater than 0.5 centimeter (0.2 inch) accumulating within a 24-hour period.

15. No work will be permitted during hours of darkness

Maintenance Exemption Summary

Maintenance (Including Emergency Reconstruction)

Pursuant to Section 404 of the Clean Water Act (33 USC 1344) and Federal Regulations (33 CFR 323.4(a)(2)), certain discharges for the maintenance, including emergency reconstruction of recently damaged parts, of currently serviceable structures such as dikes, dams, levees, groins, riprap, breakwaters, causeways, bridge abutments or approaches, and transportation structures, have been exempted from requiring a Section 404 permit. Maintenance does not include any modification that changes the character, scope, or size of the original fill design.

Emergency reconstruction must occur within a reasonable period of time after damage occurs in order to qualify for this exemption.

A Section 404 permit is required if either of the following occurs:

(1) Any discharge of dredged or fill material resulting from the above activities which contains any toxic pollutant listed under Section 307 of the Clean Water Act shall be subject to any applicable toxic effluent standard or prohibition, and shall require a permit.

(2) Any discharge of dredged or fill material into waters of the United States incidental to the above activities must have a permit if it is part of an activity whose purpose is to convert an area of the waters of the United States into a use to which it was not previously subject, where the flow or circulation of waters of the United States may be impaired or the reach of such waters reduced. Where the proposed discharge will result in significant discernible alterations to flow or circulation, the presumption is that flow or circulation may be impaired by such alteration. For example, a permit will be required for the conversion of a wetland from silvicultural to agricultural use when there is a discharge of dredged or fill material into waters of the United States in conjunction with construction of dikes, drainage ditches, or other works or structures used to effect such conversion. A conversion of a Section 404 wetland to a non- wetland is a change of use of an area of waters of the United States. A discharge which elevates the bottom of waters of the United States without converting it to dry land does not thereby reduce the reach of, but may alter the flow or circulation of, waters of the United States.

If the proposed discharge satisfies all of the above restrictions, it is automatically exempted and no further permit action from the Corps of Engineers is required. If any of the restrictions of this exemption will not be complied with, a permit is required and should be requested using ENG Form 4345 (Application for a Department of the Army permit). A nationwide permit authorized by the Clean Water Act may be available for the proposed work. State or local approval of the work may also be required.

Storm Water Comments

If high pressure water would be used to jet clean a culvert or storm drain pipes, water shall be prevented from reaching certain surface water drainages (Waters of the U.S). Discharge of pollutants to Waters of the U.S. is unauthorized by the Clean Water Act (without a NPDES permit) and by the NPDES Municipal General Permit.

If culverts/drains discharge to or within 100 feet of a Waters of the U.S. (see attached map), use methods other than water jet cleaning to remove as much material as possible. If water jet cleaning is the only method feasible to clean these type of culverts/drains, prevent wastewater from reaching the Waters of the U.S.

One method is to pump or vacuum the wastewater and removed material to a containment tank.

Removed material from jet cleaning shall be dewatered prior to disposal. Dewatering water may not directly enter the storm drain or surface water drainage.

For culverts/drains not connected to a Waters of the U.S., it may be advisable to use check dams to settle and capture soil/removed material for removal from drainage.

General Best Management Practices (BMPs):

Avoid activities if rain is in the forecast.

Do not dispose of removed material where it will re-enter the storm drain or culvert. Consult with CEIE (planner, solid waste, biologists) on method and location of removed material disposal. Material may need to be treated the same as street sweepings.

Properly dispose of any trash as solid waste.
