Jurisdictional Wetlands (cont.)

Regulatory Drivers
  • Clean Water Act, 404
  • 2.82 acres direct and 1.56 acres buffer 804 l.f.
    stream impacts
  • CERCLA (42 U.S.C. 103)
  • CWA 404 is an applicable or relevant and
    appropriate requirement. Therefore, avoidance,
    minimization, and compensatory mitigation are
    required. But, a CWA 404 permit is not.
  • AFI 32-7020 The Environmental Restoration Program
  • Under 42 USC 9621(e)(1) and 40 CFR 300.400(e),
    the portion of any CERCLA response actions that
    are conducted entirely on-site is exempt from
    requirements to obtain Federal, state, and local
    permits.

6
Mitigation Options
  • Mitigation Bank
  • In Lieu Fee Program
  • On-site (restoration, enhancement, creation, or
    preservation)

7
Mitigation Options
  • Mitigation Bank
  • None of the existing Mitigation Banks (MB) whose
    Service Areas included JB Andrews had sufficient
    available credits or the available credits were
    for the wrong type of wetland.
  • The AF was developing a MB nearby. But, the
    release of credits for that was at least two
    years away.

8
Mitigation Options
  • In Lieu Fee Program
  • There was only one In Lieu Fee Program, which was
    administered by Maryland Department of the
    Environment.
  • It was forced to expire by USACE on 19 June 2013
    as it did not comply with the 2008 Compensatory
    Mitigation Requirements.

9
Mitigation Options
  • On-site (but distant from the impact area)
  • Review of the JB Andrews INRMP (2012) identified
    several sites far away from the flightline,
    adjacent to an existing wetland and identified
    for habitat management or restoration.
  • But, the installation did not want to create
    additional wetlands.

10
Mitigation Options
  • On-site (in the area of the impact)
  • Intentionally placing wetlands in an active
    runway clearzone

11
Mitigation Options
  • On-site (in the area of the impact)
  • Intentionally placing wetlands in an active
    runway clearzone at the end of the main runway
    used by Air Force One.

12
Mitigation Requirements
  • Meets the spirit of the regulation
  • In-kind
  • Include scrub-shrub and emergent marsh habitats
  • Habitat value
  • Could not be attractive to BASH species (limited
    seed production and limited refugia)
  • Meets the regulatory definition of a wetland
  • Hydric vegetation (FAC, FACW, or OBL) and
    evidence of hydrology
  • Can withstand repeated mowing
  • Take advantage of robust plant species that reach
    maturity (seed production) at heights above the
    mowing height.
  • Native species that are commercially available
