RE: USFWS Project #2021-0077 PNDI Review # 737860

Dear Messrs. Fernández and Gluckman:

Thank you for your emails of August 12, and October 26, 2021, which provided the U.S. Fish and Wildlife Service (Service) with additional information about the Indiantown Gap National Cemetery Phase 5 Expansion Project, located in Annville, Lebanon County, Pennsylvania. The following comments are provided pursuant to the Endangered Species Act of 1973 (87 Stat. 884, as amended; 16 U.S.C. 1531 et seq.) to ensure the protection of federally threatened and endangered species. We previously commented on this project by letter dated February 25, 2021.

The Department of Veterans Affairs (DVA) proposes to construct and operate the 5th Phase expansion of the Indiantown Gap National Cemetery. Based on the materials provided, the proposed expansion is on a 120-acre parcel, but the actual development will likely be much smaller (about 45 acres) and is located east of the existing developed portion of the cemetery.

The proposed project is located within the range of the federally listed, endangered, Indiana bat (Myotis sodalis); and the federally listed, threatened northern long-eared bat (Myotis septentrionalis) and bog turtle (Glyptemys muhlenbergii).

Indiana bat and Northern Long-eared bat

In our February 25, 2021, letter, we determined that with DVA’s commitment to a seasonal restriction on tree cutting to avoid the direct take of Indiana bats, the effects of the project on the

Indiana bat were insignificant or discountable. We also determined that the project was not located within 0.25 mile of a known northern long eared bat hibernaculum or within 150 feet from a known, occupied maternity roost tree; therefore, we concluded that any incidental take that may occur was in accordance with the Final 4(d) Rule and not in violation of the Endangered Species Act. These determinations included in our February 2021 letter remain unchanged.

Bog turtle

To determine the potential effects of the proposed project on bog turtles and their habitat, Bridger Thompson, a Qualified Bog Turtle Surveyor (QBTS), conducted Phase 1 bog turtle habitat assessments on October 7 and 8, 2020. According to the report, 18 wetlands extend to within 300 feet of the proposed limit of disturbance. Following the methods described under “Bog Turtle Habitat Survey” (Phase 1 survey) of the Guidelines for Bog Turtle Surveys (revised 2020), Mr. Thompson determined that the wetland referred to as Wetland INC-W-002 had the combination of soils, vegetation, and hydrology typical of habitat occupied by bog turtles.

In our February 2021 letter, we recommended that DVA retain a QBTS to conduct a Phase 2 survey for the wetlands that were found within 300 feet of the proposed project or avoid wetlands in the project area. Accordingly, to conduct a more detailed and thorough evaluation of these wetlands, Mr. Thompson also completed Phase 2 bog turtle surveys on Wetland INC-W- 002 on April 28; May 4, 12, and 19, 2021. According to the survey report, although the site contained suitable bog turtle habitat, and several amphibian and reptile species were observed (green frog, northern dusky salamander, eastern box turtle, grey tree frog), no bog turtles were found in this wetland. Based on our review of this information, including the project description, project location, and anticipated activities; and the failure to locate bog turtles in the subject wetland, we concluded that construction and implementation of the proposed eastern end of the project is not likely to adversely affect the bog turtle.

Additional Project Area Phase 1 Bog Turtle Survey

Since the Phase 2 survey conducted in April/May 2021, the DVA selected a project design that includes additional project tasks (referred to as Additional Project Area). Work includes repaving existing roadways within the existing developed western portion of the Cemetery;

widening existing paved walkways within the mowed and maintained cemetery grounds;

installing informational signage along existing roadways; and maintaining existing monuments and bridge structures (non-structural and cosmetic repairs). The DVA is not proposing direct impacts to wetlands or watercourses in the Additional Project Area.

To determine the potential effects of the modified proposed project on bog turtles and their habitat, QBTS Bridger Thompson conducted more Phase 1 bog turtle habitat assessments in the Additional Project Area on June 10, 2021. According to the report, 19 additional wetlands extend to within 300 feet of the proposed limit of disturbance. Following the methods described under “Bog Turtle Habitat Survey” (Phase 1 survey) of the Guidelines for Bog Turtle Surveys (revised 2020), Mr. Thompson determined that the wetlands referred to as Wetland INC-W-025, INC-W-026, INC-W-028, INC-W-029 had the combination of soils, vegetation, and hydrology typical of habitat occupied by bog turtles. We concur with these habitat determinations.

Because potential bog turtle habitat was found in the Additional Project Area past the timeline requirements for a 2021 Phase 2 bog turtle survey, the DVA has elected to assume the presence of bog turtles in these additional wetland areas and employ avoidance measures to ensure no adverse effects to bog turtles, in lieu of conducting Phase 2 bog turtle surveys. To avoid adverse effects to bog turtles, the DVA has committed to implementing avoidance and minimization measures for work in the Additional Project Area. Since the project duration for the Additional Project Area is relatively short (maximum of 1 month) the DVA will use 18-inch compost filter socks (CFS) adjacent to the Wetlands INC-W-025, INC-W-026, INC-W-028, INC-W-029, per email of October 26, 2021 (to cause less disturbance within the cemetery) in lieu of traditional exclusionary fencing. The short duration of the project ensures that the CFS would remain as an effective bog turtle barrier, and not be subject to compression, crushing and flattening, thus rendering it ineffective at excluding turtles from the project area. The DVA is committed to including these avoidance measures in an approved Sedimentation and Erosion Control Plan. If all construction is completed between November 1 and March 31 and no excavation in wetlands is proposed, the following measures are not necessary.

1) If any exclusionary fencing is entirely erected between November 1 and March 31, it will not be necessary to perform a pre-construction survey.

2) During the period between April 1 and October 31, one pre-construction bog turtle clearance search of the proposed project area of effect will be completed prior to any earth disturbance activity, fencing installation, or other construction. The search area will extend to include an area 10 feet beyond the planned Limit of Disturbance and any temporary staging areas. The pre-construction bog turtle clearance search must be performed by a qualified bog turtle surveyor, who will be obtained from the most current list of “U.S. Fish and Wildlife Service and Pennsylvania Fish and Boat Commission Recognized Qualified Bog Turtle Surveyors.” The bog turtle clearance search must be completed immediately prior to the installation of the habitat protection fence described below.

3) Except as otherwise noted within these avoidance measures, the pre-construction bog turtle clearance search shall be conducted according to the most current survey protocol provided by the U.S. Fish and Wildlife Service and the Pennsylvania Fish and Boat Commission. All Phase 2 survey procedures are applicable except that one pre-construction clearance search per wetland rather than the minimum of four searches per wetland shall be acceptable, and the time of year for performing the search has been extended.

4) If the pre-construction bog turtle clearance search occurs after June 15, herbaceous vegetation within the survey area shall be cut to a height of 4 to 6 inches prior to the survey in order to promote search effectiveness. Vegetation shall be cut using a hand-held trimmer/weed cutter and then carefully raked away from the area to be searched. The qualified surveyor shall conduct the vegetation clearing.

5) Immediately following the pre-construction bog turtle clearance search, a 30-inch-high silt barrier fence shall be erected at the edge of the Limit of Disturbance as habitat protection fencing in accordance with the approved Erosion and Sediment Pollution Control Plan. The habitat protection fence shall be constructed in upland habitat between identified suitable bog turtle habitat and the limit of disturbance to deter bog turtles from circumventing the barrier. No other construction activities may begin until installation of this habitat protection fencing is completed. The habitat protection fence will act as a barrier to prevent possible bog turtles from migrating out of wetlands and waterways into the construction area and to prevent construction activity and sediment from entering the wetland and waterway. The habitat protection fencing will be installed as indicated as soon as practicable following the turtle search and clearance by the qualified bog turtle surveyor. The fencing will be installed only after receiving approval to do so from the qualified bog turtle surveyor following completion of their site search for bog turtles.

6) Installation of all habitat protection fencing and silt barrier fence for erosion and sediment control shall be the responsibility of the contractor and shall be installed and removed by hand. The qualified bog turtle surveyor shall be present during the erection of the habitat protection fence to ensure that it is properly installed at the correct location and depth. Immediately following the fence installation, it shall be inspected by the qualified bog turtle surveyor to ensure that no trench, which could act as a pit-fall trap to turtles, occurs on either side of the fencing. After installation, the habitat protection fence will be inspected and logged daily by the contractor to ensure that no holes are present that turtles can crawl through. If at any time there are holes in the habitat protection fence, OR any turtle (alive, injured, or dead) is observed within the Limit of Disturbance, construction will stop immediately, and Permit Condition 11 below will be followed.

7) All work associated with the project shall be conducted in accordance with the Erosion and Sediment Pollution Control Plan approved by the County Conservation District.

8) All equipment and machinery shall avoid wetland/watercourse habitat upstream and downstream of the proposed construction area. Orange construction fence will be installed to delineate these avoidance areas and will act as a visual warning to prevent construction equipment and personnel from entering and disturbing the potential bog turtle habitat outside the Limit of Disturbance. The Township or its designated representative(s) shall identify and clearly delineate all wetlands for the contractor(s) and will either attach the orange construction fence onto the habitat protection fence or install it immediately in front of the habitat protection fence within the Limit of Disturbance.

9) No material shall be excavated, deposited, or positioned so as to lower the water table or impede the flow of water to any wetland areas; that is, implementation of the project shall not directly or indirectly affect the water quality and quantity of any wetland areas.

10) The qualified bog turtle surveyor shall forward the results of the pre-construction bog turtle survey in writing to the U.S. Fish and Wildlife Service and the Pennsylvania Fish and Boat Commission via mail, facsimile, or e-mail within 48 hours of installation of the habitat protection fence.

11) During construction, if any turtle is observed at a location within 100 feet from the Limit of Disturbance, then construction may continue so long as there are no holes in the habitat protection fence. However, if any turtle (alive, injured, or dead) is observed at any time within the Limit of Disturbance, OR if a hole is observed in the habitat protection fence, then construction will cease immediately, and the following steps will be taken:

a. The contractor will immediately inform the pre-designated site manager who will immediately contact the qualified bog turtle surveyor. The site manager will then immediately implement the following measures:

b. If the turtle appears dead or immobile, the turtle will be left where it was initially observed. If the turtle appears to be mobile, efforts will be made to temporarily contain the turtle until the qualified bog turtle surveyor can take possession of it.

Temporary containment will consist of placing the turtle in a thoroughly clean bucket that has a depth of more than 18 inches. Less than 1 inch of water should be placed in the bucket with the turtle to keep the animal cool and hydrated. The bucket should be placed in a quiet, well-shaded area, preferably within the wetland. The turtle should be handled as little as possible, and temporary containment must not exceed 6 hours.

c. The qualified bog turtle surveyor will identify the species of turtle found and document the location and condition of the turtle. The qualified bog turtle surveyor will also inspect the habitat protection fence and direct any repairs of the fence as needed. If there are holes in the habitat protection fence and/or the turtle is found to be a bog turtle, construction will not resume until the agency consultation procedures described herein are fully implemented, and the habitat protection fence is repaired to re-establish an effective turtle exclusion barrier.

d. If the qualified bog turtle surveyor identifies the turtle species as a bog turtle

(Glyptemys muhlenbergii), then this biologist will immediately notify endangered species biologists at both the U.S. Fish and Wildlife Service and the Pennsylvania Fish and Boat Commission. The elapsed time for contacting both of these jurisdictional agencies from the time of bog turtle discovery should be as soon as possible, but must not exceed 24 hours. Following arrival of the qualified bog turtle surveyor at the project site, the turtle may be handled only by this biologist according to the recommendations of the U.S. Fish and Wildlife Service and/or the Pennsylvania Fish and Boat Commission. The biologist will consult with these agencies concerning safe handling and possible relocation of the turtle.

Construction will resume only at the completion of this consultation.

e. If the qualified bog turtle surveyor identifies the turtle as a species other than the bog turtle, and the turtle appears healthy, then the qualified surveyor will mark the turtle for future identification and release it unharmed no more than 300 feet from the site of discovery to a safe location outside of the Limit of Disturbance. The site manager will be shown how and where to release the turtle if it is again found outside of the Limit of Disturbance. Construction may continue once the turtle is relocated. The site manager must log all turtle relocations.

f. If any turtle found appears injured or dead, consult with the U.S. Fish and

Wildlife Service and/or the Pennsylvania Fish and Boat Commission concerning safe handling of an injured turtle, and the taking of possession of the specimen, whether injured or dead, by one of the jurisdictional agencies. Only the qualified bog turtle surveyor will handle the turtle. Construction will resume only at the completion of consultation.

12) The contractor will remove the habitat protection fencing and all silt barrier fencing by hand immediately upon completion of all construction activities, including stabilization of earth disturbance areas.

13) The project proponent, or designated representative(s), will submit a brief final report including bog turtle survey results and a summary of the field construction completed, including color photographs, to the U.S. Fish and Wildlife Service and the Pennsylvania Fish and Boat Commission. The final report will be submitted 30 days after construction is completed and the habitat protection fencing is removed.

With the implementation of DVA’s commitment to conduct the work under the supervision and guidance of a QBTS (in combination with the CFS as an exclusionary measure), this project is not likely to adversely affect the bog turtle. If DVA is unable to construct the project under the supervision of a QBTS (with appropriate exclusionary measures like CFS), or project plans change, please contact this office for further coordination.

This response relates only to endangered and threatened species under our jurisdiction based on an office review of the proposed project's location. No field inspection of the project area has been conducted by this office. This determination is valid for 2 years from the date of this letter.

If the proposed project has not been fully implemented prior to this, an additional review by this office will be necessary

RE: USFWS Project #2021-0077 PNDI Review # 737860

Dear Messrs. Fernández and Gluckman:

Thank you for your emails of August 12, and October 26, 2021, which provided the U.S. Fish and Wildlife Service (Service) with additional information about the Indiantown Gap National Cemetery Phase 5 Expansion Project, located in Annville, Lebanon County, Pennsylvania. The following comments are provided pursuant to the Endangered Species Act of 1973 (87 Stat. 884, as amended; 16 U.S.C. 1531 et seq.) to ensure the protection of federally threatened and endangered species. We previously commented on this project by letter dated February 25, 2021.

The Department of Veterans Affairs (DVA) proposes to construct and operate the 5th Phase expansion of the Indiantown Gap National Cemetery. Based on the materials provided, the proposed expansion is on a 120-acre parcel, but the actual development will likely be much smaller (about 45 acres) and is located east of the existing developed portion of the cemetery.

The proposed project is located within the range of the federally listed, endangered, Indiana bat (Myotis sodalis); and the federally listed, threatened northern long-eared bat (Myotis septentrionalis) and bog turtle (Glyptemys muhlenbergii).

Indiana bat and Northern Long-eared bat

In our February 25, 2021, letter, we determined that with DVA’s commitment to a seasonal restriction on tree cutting to avoid the direct take of Indiana bats, the effects of the project on the

Indiana bat were insignificant or discountable. We also determined that the project was not located within 0.25 mile of a known northern long eared bat hibernaculum or within 150 feet from a known, occupied maternity roost tree; therefore, we concluded that any incidental take that may occur was in accordance with the Final 4(d) Rule and not in violation of the Endangered Species Act. These determinations included in our February 2021 letter remain unchanged.

Bog turtle

To determine the potential effects of the proposed project on bog turtles and their habitat, Bridger Thompson, a Qualified Bog Turtle Surveyor (QBTS), conducted Phase 1 bog turtle habitat assessments on October 7 and 8, 2020. According to the report, 18 wetlands extend to within 300 feet of the proposed limit of disturbance. Following the methods described under “Bog Turtle Habitat Survey” (Phase 1 survey) of the Guidelines for Bog Turtle Surveys (revised 2020), Mr. Thompson determined that the wetland referred to as Wetland INC-W-002 had the combination of soils, vegetation, and hydrology typical of habitat occupied by bog turtles.

In our February 2021 letter, we recommended that DVA retain a QBTS to conduct a Phase 2 survey for the wetlands that were found within 300 feet of the proposed project or avoid wetlands in the project area. Accordingly, to conduct a more detailed and thorough evaluation of these wetlands, Mr. Thompson also completed Phase 2 bog turtle surveys on Wetland INC-W- 002 on April 28; May 4, 12, and 19, 2021. According to the survey report, although the site contained suitable bog turtle habitat, and several amphibian and reptile species were observed (green frog, northern dusky salamander, eastern box turtle, grey tree frog), no bog turtles were found in this wetland. Based on our review of this information, including the project description, project location, and anticipated activities; and the failure to locate bog turtles in the subject wetland, we concluded that construction and implementation of the proposed eastern end of the project is not likely to adversely affect the bog turtle.

Additional Project Area Phase 1 Bog Turtle Survey

Since the Phase 2 survey conducted in April/May 2021, the DVA selected a project design that includes additional project tasks (referred to as Additional Project Area). Work includes repaving existing roadways within the existing developed western portion of the Cemetery;

widening existing paved walkways within the mowed and maintained cemetery grounds;

installing informational signage along existing roadways; and maintaining existing monuments and bridge structures (non-structural and cosmetic repairs). The DVA is not proposing direct impacts to wetlands or watercourses in the Additional Project Area.

To determine the potential effects of the modified proposed project on bog turtles and their habitat, QBTS Bridger Thompson conducted more Phase 1 bog turtle habitat assessments in the Additional Project Area on June 10, 2021. According to the report, 19 additional wetlands extend to within 300 feet of the proposed limit of disturbance. Following the methods described under “Bog Turtle Habitat Survey” (Phase 1 survey) of the Guidelines for Bog Turtle Surveys (revised 2020), Mr. Thompson determined that the wetlands referred to as Wetland INC-W-025, INC-W-026, INC-W-028, INC-W-029 had the combination of soils, vegetation, and hydrology typical of habitat occupied by bog turtles. We concur with these habitat determinations.

Because potential bog turtle habitat was found in the Additional Project Area past the timeline requirements for a 2021 Phase 2 bog turtle survey, the DVA has elected to assume the presence of bog turtles in these additional wetland areas and employ avoidance measures to ensure no adverse effects to bog turtles, in lieu of conducting Phase 2 bog turtle surveys. To avoid adverse effects to bog turtles, the DVA has committed to implementing avoidance and minimization measures for work in the Additional Project Area. Since the project duration for the Additional Project Area is relatively short (maximum of 1 month) the DVA will use 18-inch compost filter socks (CFS) adjacent to the Wetlands INC-W-025, INC-W-026, INC-W-028, INC-W-029, per email of October 26, 2021 (to cause less disturbance within the cemetery) in lieu of traditional exclusionary fencing. The short duration of the project ensures that the CFS would remain as an effective bog turtle barrier, and not be subject to compression, crushing and flattening, thus rendering it ineffective at excluding turtles from the project area. The DVA is committed to including these avoidance measures in an approved Sedimentation and Erosion Control Plan. If all construction is completed between November 1 and March 31 and no excavation in wetlands is proposed, the following measures are not necessary.

1) If any exclusionary fencing is entirely erected between November 1 and March 31, it will not be necessary to perform a pre-construction survey.
