Amendment 0004 - Questions and Answers

1. In regards to the period of performance, will weather delays (due to heat) be considered during summer months? Completing this project quickly and efficiently is a critical goal of this contract. No one shall be required to work in unsafe working conditions.

2. Will the government please provide a specific dump site for export material and/or can it be spread along the path of the trails? If a specific dump site is required, please show it on the map – as it impacts hauling time/costs (depending on location). Excavated material may be used on site as fill or stored at a nearby location on the refuge for future use by staff.

3. Will there be multiple staging areas around the refuge? Please designate all available staging areas on the maps. Contractor is required to stay within the Area of Potential Effect (APE, map provided with the amendment). Certain existing parking lots or areas in the existing maintenance yard may be used as staging areas. Exact location to be determined post-award.

4. Is there a source of water at the refuge available for contractor’s use? If so, will this be free, or will metering be required? Water for the project will be available on site, free of charge.

Any non-FWS water hauling equipment will need to be inspected by FWS staff and decontaminated prior to use. Inadvertent movement of species is a big concern at this location.

5. In regards to the use and compaction of native materials for the trail, and to ensure all teams are bidding “apples to apples”:

a. How deep should bidders assume we will have to moisture condition for compaction of the paths? Where existing paths and/or roads are reused as trail surface, no compaction shall be assumed necessary. For new trail sections and where grading is necessary to meet slope and width requirements, grading and compaction shall occur using hand tools only. 85% compaction shall be deemed sufficient for disturbed areas. Trail surface testing will be by FWS in hiking boots.

Minimal surface disturbance is a goal for this project.

b. For areas of saturated soil that cannot be avoided (such as possible areas of the Cold Spring Trail), can the government provide an assumed volume of material that the contractor will be responsible for replacing (over excavation and replacement with a suitable alternative)? For purposes of our bid, any amount below this assumed quantity would result in a credit back to the government, while any amount above this quantity would result in a change order to the contractor. Over excavation and fill is not permitted on this project unless deemed necessary for life-safety related reasons.

6. Can the government provide a known source for the tufa rocks for the path lining and parking area boundaries? (either alternate commercial sources or areas of the refuge where we may be able to source these rocks)? If no commercial sources exist, and we do not have adequate quantities generated from the refuge, please provide what “other USFWS approved edging” would be (as mentioned in the 35% design, page 14, paragraph 3.4). No rock is readily available on the refuge, rock from an excavated project areas can be used but is not typically abundant in the soil strata on the refuge. The mine operators in the area (Lhoist or KMI Zeolite) have tufa rock spoils available. Alternative material may be identified and proposed by the bidder.

7. Are there any known utilities that may conflict with the excavation and earthwork anticipated on this project? If known, please provide any additional information (location, depth, utility provider, etc.). None are known. Successful bidder should confirm with local utilities and/or Call-Before-You-Dig.

8. Please confirm that all of the cultural resources survey has been completed for the anticipated work areas. If routes or locations of work are modified (outside of the “cleared” areas), who will be responsible for the new cultural resource survey/clearance (government or contractor responsible)? The cultural resources survey has been completed for the anticipated work areas. Routes or locations outside of the ‘cleared’ areas are not desired. If it becomes necessary to evaluate additional areas for cultural resources compliance this will be addressed by the government.

9. Have the USACE permits been approved/received by the government? The permit application is currently being processed by the USACE. Estimated completion is late June to mid-July (or earlier).

10. Per the SOW, the “Clearing of vegetation during construction along trail alignments must occur outside of the migratory bird breeding season of March 15th through August 15th”.

Please confirm if there are any other Restricted Activity dates/periods that would impact construction activities on the project. No other restricted activity dates/periods.

11. Will the government provide the SNPLMA nomination package prior to the bid date? The SNPLMA nomination will not be provided to avoid confusion. The project has evolved since the nomination, and we ask that you use the 35% Design Documents to review the design intent.

12. In regards to the Interpretive Design Workshops: will these be held via Teams? Or are we to assume (in addition to the 2 site visits) that these 4 workshops will be held in-person? If held in person, will the Refuge provide space to conduct these workshops? If the government will not provide space, what is the acceptable “radius” from the project site that these workshops may be conducted? TEAMS is an acceptable platform for the design workshops. The interpretive elements can be covered as part of the general design workshops. Refer to amended Scope of Work.

13. In regards to the interpretive and design reviews, the SOW indicates that we must provide 1 month (minimum) for review. Please confirm this 1 month review is concurrent with all parties involved in the review process. Yes, the review will be concurrent with all parties.

14. Will the government manage formal communication and reviews with Indigenous partners/stakeholders at key design phases? Or will this be the responsibility of the contractor team? Yes, FWS will manage communications with Indigenous partners.

15. Should the design include budget for Indigenous language translation? No.

16. How many days/hours are envisioned for the two site visits and four workshops? See amended Scope of Work.

17. Are all, or some of these meant to be designed to Accessible Trail Standards? After designing and constructing a native surfaced fully accessible trail here 2 years ago, it is very difficult to do so unless you are using a hardened surface such as a boardwalk. Refer to the design requirements in the 35% Design Documents, Appendix C.

18. Are you seeking just a center-flagged and GPS'd alignment, or construction recommendations in terms of puncheons, boardwalks, surfacing material, etc.? This is a design-build contract to provide the scope of work as described in the solicitation (design and construction).

19. I did not see a map containing topographical lines underlying the proposed routes - do they have this, with perhaps 20' contours? Pretty much a necessity for me to be able to put together any design on the computer. A limited topographical survey was provided with the solicitation. No other topographical information will be provided by the USFWS.

20. On the OVERVIEW MAP DESIGN TRAIL TYPES (Sheet S3), there are the following categories listed in the legend and depicted on the map:

a. DESIGN TRAIL EXISTING BERM - What exactly does this one mean? This means that the trail shall follow the existing berm.

b. DESIGN TRAIL EXISTING ROAD - Does this indicate where the trail will simply follow the existing road? Or go besides the Road? The trail will follow the existing road.

c. DESIGN TRAIL EXISTING TWO TRACK PATH - Does this indicate where the trail will simply follow the existing two-track path? Yes.

21. If I am to assume that the intended route does indeed follow the existing road and two track (and berm?) where indicated on map S3, there is significantly less actual new trail to be designed so this would be an important point to clarify. However....on the more zoomed in maps (S4-7) just about everything is indicated as DESIGN TRAIL ALIGNMENT rather than depicting the EXISTING BERM, ROAD AND TWO TRACK PATH segments as on S3. So it is unclear in my mind what they want designed, and what they want to use in terms already existing roads, two-tracks and berms (and not sure what their "berm" really is. See response to question above.

22. Back to the question regarding topographical lines, in reading through the documents further it may be that most of this lies on almost flat terrain? Yes, this is a seasonal wetland with minor elevational changes.

23. Section 1.10 Regulatory Requirements states “ Clearing of vegetation during construction along trail alignments must occur outside of the migratory bird breeding season of March 15 through August 15 (USFWS 2022).” Would this include all parking areas? The goal is to get the construction work done after the 2025 bird migratory season ends and before the 2026 migratory bird season begins.

24. Should all design costs be incorporated into the base bid? Yes.

25. Parking Area Design: “Standard cross section includes 8 inches of Type II crushed aggregate base and 3 inches of 1-inch minus crushed aggregate surface material.” If we are not excavating and removing existing soil, this parking area will be raised about 11”, will we need to ramp up the road as it approaches? Or are we removing native to limit the elevation gain?

Solution shall be developed during the design phase. Minimal impact to site drainage patterns is of critical concern to the nearby spring system (avoid run-off).

26. Rogers Spring Overlook: “The overlook area will be located immediately adjacent to the UCS Loop trailhead. The overlook will be a constructed boardwalk matching the design found at Longstreet Spring. This includes a low-profile walking boardwalk path and viewing area contained by metal railing with wood caps.” The material used here is treated wood. When used in hot temperatures, the oils in the wood will leach out and drip into the environment.

(Considered hazardous in CA) Is the intent to use “treated wood”? Other Projects have specified a Thermally Modified Wood… There are environmentally acceptable pressure treatments such as ACQ. Contractor may propose the use of thermally modified wood.

27. Also, it appears that the foundations are cement blocks, is this design acceptable or will you require helical piles? (Helical Piles will be much more expensive and do require larger equipment for install) Any required foundations will be designed by the successful bidder.

28. Sidewalk note states: “COMPACTED NATIVE OR IMPORTED TYPE 2 BACKFILL”, is there a compaction requirement on native material below baserock? Compaction is required under concrete sidewalk, per drawings. For compaction of trail surfaces, see response to question above.

29. The plans show 95% compaction in areas. What are the testing requirements for concrete and base rock? How often will these tests need to be performed? Contractor to engage testing agency to test the compaction of soils under the concrete sidewalk areas.

30. Tufa Rocks plans state “EDGING OF DESIGN FEATURES TO BE COMPLETED USING TUFA ROCK COLLECTED ON SITE” – Is there sufficient tufa rock onsite? If not, can this be brought in locally? Or will an alternate be accepted? See previous question regarding local availability of tufa rock. Alternate solution may be considered.

31. Typically rocks/boulders are buried 1/3 of their size. Is that the expectation of the Tufa? Yes, this is expected for rocks over 18”.

32. The plans show 24” Tufa rocks, this would be based of the longest span of the rock, correct?

Yes.

33. Plans State” INSTALL TRAIL EDGING WHERE DESIRED TO DELINEATE TRAIL AND/OR PROTECT SENSITIVE OFF TRAIL AREAS” - who determines these areas? Do you have a LF idea at each trail of expected edging not shown on the plans? For bidding purposes assume 25% of the trail to be edged. Exact areas will be determined during the design.

34. Is there a compaction requirement on native trails? If so, what are the testing requirements? See response to question above.

35. Will a hydrant be available for water usage? Will we be charged per gallon? If so, what is the cost per gallon. See response to question above.

36. Page 8 of Tech Requirements states: “NOXIOUS WEED, SPECIES AND PATHOGEN CONTROL Wash any equipment (and transport trucks) at an approved site before entering the project area. This is particularly important when transporting material or equipment from relatively distant areas. “ Please provide the process for all equipment and trucks entering the site. Will inspections be required? How much notice? Where would these inspections be held? FWS Inspections will be required at mobilization. Inspections will be held at the maintenance shop area.

37. Will the Prime need to have any 3rd party Culture Resource Expert? If so, please describe their involvement. “Page 8 of Tech Requirements states: - Cultural Resources: Immediately stop work if paleontological, archaeological or historical remains (including burials or skeletal material) are encountered, until work is permitted to resume by written order from the Contracting Officer. Notify the Inspector, COR, or Contracting Officer immediately. The Contracting Officer will notify the Regional Archaeologist, so 36 C.F.R. § 800.7 (Resources Discovered During Construction) and other relevant laws are followed. Work in other areas may proceed as approved by the Contracting Officer.” No 3rd Party Cultural Resource Expert is required.

38. If the Government is overseeing these Cultural Elements, will training be needed? Will training be needed for ALL workers, and or subs? Or can the Primes superintendent get training and relay information through daily safety meetings and reminders. No training is required. Yes, information can be relayed during daily safety meetings.

39. Where will staging areas be located? See previous response to the same question.

40. Is there a Geotechnical Report? No.

41. Can any CADD or survey files be shared or will they be available if awarded? The CADD survey file was provided with this solicitation. No other CADD files except for USFWS titleblocks are available.

42. The Solicitation shows 270 calendar days for this project from NTP. We anticipate 30 days of design per submittal and the SOW states that the government will need a “minimum” of 30 days to review. That means 60 days from 35% - 65%, another 60 days from 65% - 90% and another 60 days from 90% - Final (Total of 180 days for design, minimum) That gives the contractor 90 days to perform the work. Is the 270 days for the base bid only? Schedule is of critical concern, though the execution of options may extend the project duration.

43. Will construction be able to start prior to final design approval? Certain activities like site clearing may start prior to final design approval.

44. The image of the water crossing appeared to be red cedar, not treated wood. Please clarify the material desired. Image is not intended to convey actual material. Contractor may propose appropriate material for water crossings (refer to design narrative).

45. For design, Do we need to meet with the tribe(s) and/or attend any workshops? Tribes may attend workshops. Contractor will not be required to attend additional meetings with the tribes.

46. Do the Tribes need to be paid for their time and services? If so, by whom? There will be no payment to the tribes required by the successful bidder.

47. What is the anticipated Start Date? (270 C/D duration, 3 months of engineering and redline, Migratory Bird moratorium ends August 15th. Daily high temps in Summer) To be determined pending award of project (June or July 2025).

48. What is the source for Construction water? See response above.

49. Will the Prime Contractor need to include the services of an interpretive Manager? An interpretive designer may provide necessary expertise to complete the interpretive scope elements of the project.

50. There is language in the Solicitation (Mitigation Commitments) that USFWS will have a biologist monitoring all activities in the project area. Will the Prime need to include additional Bio-Monitoring services in our submission? No, FWS staff will perform all bio-monitoring functions.

51. Does USFWS see a conflict if the Prime was to partner with Alta and or OTAK? No conflict if either is performing as a subcontractor.

52. 35% design sheet D6 details the Tufa rock to be used as a border in some locations. Is there a local source for this material? See question above.

53. Has a staging area been designated for the Contractor? See earlier question.

54. The proposed Northen section of the UCS Loop Trail is in proximity to an existing

Administrative Road. Is the intention of the design for the trail to run on or adjacent to the existing road? Yes. Using existing road surfaces where these coincide with trail routing is acceptable (and desired).

55. Improvement plans show a Desing Stream Crossing on the UCS Trail, and it is assumed that a crossing structure will need to be included in Bid Item CLIN 0030. The plans also show two Designed Stream Crossings on the Cold Springs Trail. It is also assumed that these additional crossings should be included in Bid Item CLIN 0080. Please confirm if this is the case. Stream Crossings should be included with the respective trail sections. A crossing on the UCS trail section should be included with Task 1, and a stream crossing on the Cold Springs trail should be included with Task 6.

56. Is there a designated area for the disposal of trail slash and excess excavated soils? If so, what is that location? Small amounts of vegetation can be scattered, no piles are to be created. Large amounts of trail slash will need to be disposed of at the burn pile (36.401633°, -116.264231°), if fill is unusable at another project site it can be relocated to this same area.

57. Outside of the Survey Control points that have been established and provided has the proposed trail alignment been established via GPS? If so, can he get that data? The GIS shapefile will be provided to the successful bidder.

58. Where the proposed trail system is called for in a previously undisturbed location is the intent to remove vegetation and objects protruding in the trail, as called for in the 35% design only? Or is the intent to scarify the existing soil to a certain depth, moisture condition and compact? If this is the intention, is there a compaction percentage specification? Is there a testing frequency? Has a Geotechnical investigation conducted? If so, was native soil sampling done? Has a Geotechnical report been completed? Yes, remove vegetation and only disturb soil where necessary to create a flat foot path 3’ wide with turnouts as required per pre-design. Use only hand-tools. No geotechnical investigation has been performed; no geotechnical report is available.

59. Same question as above but for proposed trail locations in previously disturbed locations or where the trail is proposed where is shares the administrative road system? Same answer as above.

60. This area (like most of the region) is extremely arid but is prone to flooding. Given the soil and the approximate flood zone boundary established, should the trail be built outside of flooding areas? If so, what criteria should be used? Trail shall be located per the 35% design documents. Criteria for the trail design are established in the 35% design documents.

61. 95% compaction indicated on the 35% drawings is fairly restrictive for this rural application. Is the native dirt going to be on the top of the trail (assuming there is no import for the trail), if not, what is the government expecting? 95% compaction is expected underneath concrete paving (sidewalk areas).

62. Understood that the wooden elevated footpath is required at wetland areas, however at stream crossings, what type of crossing is the government expecting? Refer to the 35% Design Documents for recommended stream crossings.

63. Are there any geotechnical/soils reports that can be made available? No.

64. Are there environmental studies or reports that need to be completed as a part of this project? No.

65. Will all clearing and grubbing material from the trail be scattered on site or hauled off? Haul large amounts to burn pile (see answer above).

66. What soil conditions have been identified in the project area, and will geotechnical reports be provided? No geotechnical report has been completed.

67. What are the parameters for design in regards to potential flood zones or at stream crossings? Refer to the design parameters for the trail as provided with the scope of work.

It is understood that simple footbridges may wash out during major flood events.

68. It is listed that permit requirements will need to be met to obtain permits, but are there specific key permitting requirements for this project that are already known or required by US Fish and Wildlife (e.g., NEPA compliance, wetlands permits, etc.)? The contractor is expected to prepare and adhere to a SWPPP (Stormwater Pollution Prevention Plan).

USACE and NDEP permits will be provided by FWS (currently in progress). No heavy equipment will be permitted in the proximity of wetlands and waterways.

69. Are there any historical or archeological considerations already known by US Fish and Wildlife that could impact trail alignment or construction methods? We have designed the trail alignment to avoid historical and archeological sites. Tribal monitor may be present.

Refer to Mitigation Measures included with the solicitation in case of discoveries.

70. It is noted that the government will inform construction team of issues and/or changes regarding endangered species and other environmental impacts, but are there any environmental studies that the designer/contractor team needs to take on responsibility for performing as part of scope for project? No.

71. What are the restrictions on construction schedules other than fire danger and weather considerations that are already known by US Fish and Wildlife (e.g. working hours, wildlife protection periods)? Refer to the Scope of Work for the migratory bird season restrictions.

No other restrictions are known at this time. Unforeseen restrictions that occur due to weather or emergency issues will be communicated properly during the project.

72. Other than the alignment of the trail, what level of detail is desired for the complete trail design (e.g. plan and profile for every few hundred feet of detailed disturbed area, etc.).

Limited detail is required. Alignment is critical, and avoiding disturbance is also important.

Detail is at contractor’s discretion for areas of particular concern (steep slopes, intersections etc).

73. Where the trail combines with existing road, what improvements are desired to be made?

Please refer to initial design; further improvements may be proposed and discussed during the design phase.

Upper Carson Slough Backcountry Trail System Design-Build Contract

Statement of Work

Design and Construction Services

United States Fish and Wildlife Service Ash Meadows National Wildlife Refuge – Amargosa Valley, NV

November 14, 2024

1. BACKGROUND:

Ash Meadows National Wildlife Refuge (AMNWR) was established in 1984 to preserve the Mojave Desert’s largest remaining oasis and “conserve and recover listed endangered, proposed endangered, and candidate plant and animal species found in the area”. Approximately 50 seeps and springs generate 17,000 acre-feet of water per year, providing habitat for at least 26 plant and animal species found nowhere else in the world including 13 species listed as threatened or endangered. AMNWR is a true biodiversity hotspot, supporting the second highest density of endemic species in North America.

Ash Meadows is also part of the Nuwu/Nuwuvi (Southern Paiute/Chemehuevi) and Newe (Western Shoshone) ancestral lands. These Indigenous peoples consider Ash Meadows as a place of creation and imbued with spiritual power since the beginning of time when the world was new. Several of the locations and endemic species at Ash Meadows have critical cultural roles for these peoples, which are embedded in stories, songs, rituals, and traditions.

Many of the springs at AMNWR were developed to provide water for agriculture and other uses. The primary management priority since refuge creation has been to restore these springs to improve habitat conditions for native fish and wildlife species. The Upper Carson Slough (UCS), located in the northern end of AMNWR, is an important wetland area fed by several major springs including Fairbanks, Soda, Rogers, and Longstreet Springs, among others. A recent restoration effort, completed in 2014, restored the historic function to these springs and the UCS.

With the UCS springs and outflows returned to their historic function, a backcountry trail system was planned to provide access to nature, interpret the area’s unique ecology, and highlight the cultural legacy of Indigenous peoples. At present, the refuge has several excellent boardwalks with interpretation, but opportunities to explore the backcountry are rare. The goal of this work is to create a backcountry hiking, hunting, and nature exploration opportunity for Ash Meadows NWR visitors.

Funding has been secured through the Southern Nevada Public Land Management Act (SNPLMA). The approved SNPLMA project description is included with the solicitation and serves as a guiding document for the project implementation.

Coordination with agency and tribal partners will be required for successful project. Tribal collaboration and engagement will be facilitated through a separate cooperative agreement. Sufficient time should be allotted for review of design deliverables by USFWS staff and agency partners. One month (minimum) will be required for each review of the design deliverables.

This contract includes the final design of wayfinding and interpretive signage for trail system and overlooks. A preliminary design for the interpretive elements was completed in a previous contract and serves as a guide to the completion of this scope. It is essential that the tribal partners will be engaged in this effort to refine the design. The scope includes associated trailheads and trail wayfinding signs. A series of site visits and workshops with agency staff and tribal members will be held to refine the interpretive themes and specific sign language to interpret the cultural and ecological significance of Ash Meadows and the UCS. The interpretive exhibits shall enhance the visitor experience of this area, create meaningful connections to the resources, and provide for resource protection.

Note that the 35% Design which is provided as a basis of design for this contract may require adjustments in the field. The trail alignment may need to shift if cultural and biological resources are discovered or encountered in the field.

2. GENERAL INFORMATION:

2.1. Provide general design, interpretive design, and construction services for the Upper Carson Slough Backcountry Trail project at Ash Meadows NWR. A schematic design is provided as a starting point. The interpretive storyline shall be integrated with the trail experience.

2.2. Provide construction services for backcountry trail segments, parking areas and overlooks.

Final alignment of trails shall be coordinated with FWS staff and tribal partners and accommodate necessary adjustments arising from biological or cultural resources surveys.

2.3. Bid Schedule includes Base Bid and Option Bid items. Option items may be awarded within 90 days after the Notice-To-Proceed of the awarded contract and are subject to availability of project funds.

2.4. Period of Performance: The anticipated performance period for this contract will be 270 days from issuance of the Notice-to-Proceed, including agency review time. Note that the start of construction is pending receipt of USACE permits and Cultural Resources Clearance, both currently in progress.

3. GENERAL DESCRIPTION:

3.1. See attachments for details regarding the UCS Backcountry Trail Design, parking lots, overlooks, and associated interpretive elements and storylines.

3.2. The UCS is a flood-prone wetland. It is also home to many wetland-associated threatened and endangered species. Both to minimize the potential for flood-related trail damage and to avoid altering the habitats of endemic species, all elements have been designed to minimize habitat or hydrological alteration while avoiding wetland and marsh areas to the maximum extent practical.

3.3. The work will comply with outdoor accessibility standards and requirements (see attachments) as indicated.

3.4. The materials used on the project site shall match what is currently in use at the Ash Meadows National Wildlife Refuge for continuity of the visitor experience. Final material choices will require approval by FWS.

4. PROJECT TASKS:

Ash Meadows National Wildlife Refuge – Decontamination Compliance Form (Updated May 2024)

Ash Meadows National Wildlife Refuge Decontamination of Clothing, Equipment, and Supplies

Non-native plants and animals have caused significant damage to native species in many areas, including at the Refuge. Ash Meadows additionally contains local-scale diversity and endemism within its boundaries, with some aquatic organisms, such as certain species of spring snails, existing only within single or select seeps and springs. Specialized species and animal communities in these areas are prone to impacts and even extirpation by researchers carrying microscopic organisms on clothing and gear when moving among waterways on the Refuge. Thus, each aquatic system on the Refuge must be treated as an isolated system for biosecurity purposes.

Ash Meadows employs a cleaning and two-step decontamination method to avoid the introduction and movement of both terrestrial and aquatic organisms. This approach has proven especially effective (and necessary) against difficult-to-treat species, such as operculated gastropods, bivalve mollusks, and crustaceans. This method is outlined below and further detailed in the attached Ash Meadows NWR Biosecurity SOP.

After following the below decontamination process, gear should be stored in labeled containers or a designated area to avoid cross-contamination prior to use. Researchers arriving at the Refuge are required to coordinate with designated staff before commencing their fieldwork to review the decontamination measures taken and gear inspection. If procedures are found to have been inadequate, the project may be delayed until compliance can be achieved. Researchers are required to provide documentation of their compliance (see the attached Decontamination Compliance Form).

a) Clean and Decontaminate: WE STRONGLY RECOMMEND RESEARCHERS ACQUIRE NEW

GEAR, CLOTHING, AND FOOTWEAR FOR EXCLUSIVE USE AT ASH MEADOWS NWR.

However, in situations where this is impractical, researchers must clean, decontaminate, and disinfect gear BEFORE their visit, as follows.

i. Clean: Thoroughly clean all vehicles, gear, equipment, clothing, and footwear. Remove ALL mud and contaminants that may harbor weed seeds, plants, aquatic organisms, or other invasive organisms of concern. Use detergents and brushes as needed, as any residual mud or contaminants will render the next steps ineffective.

ii. Disinfect*: For footwear, gear, or equipment used in outside aquatic habitats, soak items in a solution of 2% Virkon® Aquatic** for 20 minutes OR quaternary ammonia at the mixture-dependent concentrations listed below (Table 1). These treatments will kill most fish and invertebrate pathogens and invasive aquatic invertebrates. Rinse the gear thoroughly after soaking.

*Chemical disinfection is only required for items used in/near aquatic systems outside of Ash Meadows NWR.

** Virkon® Aquatic does not contain the fragrances and dyes in other varieties of Virkon that may be harmful to aquatic organisms.

b) Freeze*: The second step in the process is to freeze ALL footwear, gear, and equipment that has encountered aquatic ecosystems both within and outside the refuge** at ≤ 20°F (-5°C)for a minimum of 5 hours to kill any remaining individuals not killed by chemical disinfection. The Refuge maintains a dedicated freezer for equipment decontamination for this purpose (i.e., when moving among wetted areas on the Refuge). Researchers must complete this step for gear brought in from outside the Refuge (after chemical disinfection) as well as between moving among different springs and wetted areas on the Refuge.

*The researcher will discuss any special considerations required for sensitive electronic gear prone to damage from freezing with the designated FWS staff in advance.

Acquisition of duplicate equipment may be required.

**The freezing step must take place even when moving between different aquatic systems on the Refuge to avoid transferring species endemic to one spring system to another.
