7.0 RECOMMENDATIONS
7.1 Aquatic resources
The project will not affect the banks of Parachute Creek. Control of drainage and using Best
Management Practices (BMPs) to reduce or eliminate possibility of release of toxic substances
will greatly minimize potentially detrimental impacts to aquatic resources.
Avoid highly alkaline areas along Parachute Creek to preserve vegetation stmcture and diversity.
I
7.2 Avifauna
Reduce or eliminate impacts to sllucturally diverse sh!Ublands and riparian shrubs and trees.
No active raptor nests were found within% mile of the project area. If nesting raptom are found,
constmction should be scheduled between tenitory establishment and dispersal of young from
the nest. WWE recommends temp.oral and spatial restrictions for activities near active nests
based on BLM stipulations, CDOW recommendations (CDOW 2008b; Craig 2002; Craig and
Enderson 2004), and literature review of nesting se!ll\on timing for raptors in the Roan Plateau
region(Andrews and Righter 1992; Kennedy and Stah!ecker1993; Kingery )998; Poole2005).
These recommendations are summarized in Table 10.

* Grut Homed Owls are relatlvelytoleraut ofhumiLn activity. Keep activity to a minimum during breeding season.
Timing restl'ictions and dates may be modified if an active nest is monitored by a qualified
biologist. The bnffer zone should not be entered until one week after the young have fledged,
which can be much earlier than standard temporal restrictions.
7.3 American ell( aod mule dee1·
For deer and elk, the most critical time period is winter. The project area ·is located within
important winter range for both species. Seasonal restriction to limit major work activities are
recommended in Table 11. Table 11 also includes seasonal critical periods for raptors and
migratory songbirds. .

7.4 Black Bear Measures
Black bears are known to occur in the vicinity, and all personnel should be aware of their
presence and take important safety measures when working in the area. Prevent any undeSirable
encounters by refl-aining from feeding bears, and by keeping all trash and food waste in bear-
proof contabiers. Put dog food and bowls, cooking appliances and utensils in besr-proof storage
at night.
7.5 Minimize footprint of disturbance
Reduce to the minimum level possible all soil disturbing activities. Park constmclion vehicles
on previously disturbed lands during construction. to fut1her reduce temporruy disturbance. '
Preserve as much saline saltbush shrub land as possible.
7.6 Re~seeding
It is recommended that temporaty and permanent disturbances be re-seeded with native grasses.
These measW"es are described in an Integrated Vegetation and Noxious Weed Management Plan
for this site. J3MPs should be followed as described in the integrated vegetation management
plan.
7.7 Fence Removal
Re-built fences that axe designed for easy passage of deer and elk can allow these animals to
utilize the native and planted vegetati<;m for forage and move about the adjacent areas freely as
they search for food arid cover. ln addition, properly designed fences will prevent deer and elk
from heing injured or suffering death as a result of becoming entangled as they attempt to jump
over or pass through a fence. Generally, wire fences that do not exceed 42 inches in height and
have 12-inch spacing between the top two wires will allow deer and elk to pass over a fence
without injury. The BJ,M utilizes these fence specifications for livestock fencing on federal
lands (BLM 1989). The publication presented by CDOW, "Fencing With Wildlife In Mind"
provides fence designs that are friendly to wildlife and is available at the CDOW web site at
wildlife.state.co.us/NRlrdonlyres/BOD65D61-6CB0-4746-94Fl-6EE194BlC230/0/fencing.pdf

Waste Management (WM)
Description
Stormwater n.inolf from areas where construction wastes are stored or disposed can be polluted. Wastes
leached or spilled from management areas may buHd up In soffs or on other surfaces and be carried by
stormwater runoff. The optimal approach to reduce the potential for slormwater contamination from wastes is
to reduce the amount generated and, consequently, the amount stored on site. The following types of waste
management are covered under this BMP:
Concrete waste management: Practices to be used In order lo minimize and prevent concrete waste
associated with construction activities from entering storm drains and watercourses. Concrete waste may be
generated where concrete trud<s or concrete.coated equipment are washed on site, where slurries containing ·
concrete are generated. or where mortar-mixing areas exist. .
Solid waste management: Practices to be used in order to minimize and prevent solid wasje assocla\ed with
construction activiH~s from enlerlng storm drains and watercourses. Solid waste can be classified as non--
. hazardous solid material including: concrete, rod<, debris, soli, wood, vegetative material, plasUc, fabfics,
mortar, metal scraps, Styrofoam, and general litler such as but not limited to beverage containers and plaslfc
wrap pelS.
Sanitary and septic waste management: Practices to be used In order to minimize and prevent sanitary and
septic waste associated with oonstructlon activffles from entering slorm drains and watercourses. ·
Llgujd wasta management: Practices to be used In order to minimize and prevent liquid waste associated with
construction activities from entering storm drains and watercourses.
Hazardous waste management: Practices to be used in order to prevent hazardous wasta associated with
construction activftlas from ente~ng storm drains and watercourses. Hazardous wastes may be discovered or
generated (by lead paint removal operations) and are designated as hazardous by the Code of Federal
Regulations or Colorado slate laws. ·
Contaminated wasta management; Practices to be used in order lo minimize end prevent pollutanls from
contaminated soils from leaching into waterccurses or drainage systems.

Applicability
Fadlities or designated construction work are"\s where each type of waste is discovered or generated.
Limitations
During the non-rainy season or In arid portions of the state, temporarY stockpifing of non-hazardous solid
waste may not require slrtngent drainage control measures. The engineer for the project shall determine if
drainage cortrol measures are warranted for a specific construction site where non-hazardous solid waste is
being stockpiled. ·
Liquid waste management does not apply to solid wastes, hazardous wastes, concrete slurries/wastes,
dewalenng operaUons, sanitarY/septic wastes, or permitted allowable non-stormwater discharges. Disposal of
some liquid wastes may be subject to regulations or requirements of other permits secured for the construction
site.
This BMP provides general hazardous wasta management guidelines,.buto;!oas not relieve the contractor from
full responsibility of complying with federal, state, and local laws r~ardlng storage, handling, transpor!aticn,
and disposal of hazardous wastes. It ls the contracto( s full responsibility to identify all hazardous waste
generated at the project site.
The contractor is responsible for identifying pollutant-specific handfing ;md disposal procedures lor
contaminated soils at lha project site.
Standards
Concrete waste
Waste generated li'om concrete activities shall not be allowed to ftow into drainage ways, Inlets, or receiving
waters.
Concrete waste shall be placed in a temporary concrete washout facility.
•
•
•
•
•
•
Concrete washout faCilities wilt be comprised of an excavation with erosion bales and construction
fences along the perimeter, The facility may be similar to the settling devlca used for dewatering (see
-Figure OW-1 ) .. The bottom of the excavation must be proven to be al least 5 vertical feet above .
groundwater or, alternatively, the excavation niust be lined wllh eRher a clay or synthetic liner that is
designed lo control seepage. The facilllles shall be maintained in good condition to conlain all liquid
and concrete waste generated by operations at a project sfte.
Proper signage such as "Concrete Washout' shall be placed near concrete washout facilities to Inform
construction personnel of the location of designate6concrete washout facililies.
Temporary concrete washout facilities shall be located 50 horizontal feet from drainagew~ys, inlets,
and receiving waters unless othe[Wise approved by the engineer,
Adding solvents, flocculenfs, or acid lo washwater is prohibited .
Whenever a concrete washout area is within 300 feet of the access to a road or highway, a stabilized
conslructlon entrance must be buHt as part of Uhe washout, or at the entrance to the road or highway,
Hardened concrete wasle shall be properly disposed of following solid waste management
procedures.
• Removal of temporary facilities, including the solid concrete waste and the material used to construct
the facilities, shall be the responsibility of the i:ontractor, who shall remove !he waste from the project
site and dispose of it prope~y foliow!ng gufdelfnes outlined in solid, liquid wasta management and any
applicable regulations. ·
