Planning

− Env. Check list was used when developing work plans

− Env. Manager must sign off on all work plans. − Include all Env. concerns

− SPCC and SWPPP signature pages

− Include specs and standards of E&S controls

− Attend prep meetings and kickoffs

Meetings

− Environmental Coordination Meeting − Every other week there was a meeting held between ERC and

VDOT (Project Owners)

− Once a month there was a field inspection with ERC and VDOT (Project Owners)

− Regulatory Agency Meeting − Held every quarter with those having permit or ownership over

the project

− ERC/VDOT (Project Owners)

− Army Corps

− VA Department of Environmental Quality

− VA Marine Resources Commission

− US Coast Guard

Challenges & BMPs

Slide 28

Dredging operations were

conducted using an

environmental bucket

whenever possible.

Dredging operations removed

over 20,000 tons of TPH

contaminated soil from the

Elizabeth River.

Slide 30

The project designed and used

a bin block system to build a

decanting system to dewater

dredge material.

The system successfully removed

the material from the water allowing

only clean sediment free water to be

discharged.

The project removed

1,000’s of piles from

the Elizabeth River

– Many creosote

The project chose to

perform insitsu treatment

of lead contaminated

soil.

Using this method

reduced hazardous

waste.

Treatment was a lower

cost then shipping off as

hazardous waste.

The project utilized a self

contained tire wash system.

The system reduces the

risk of environmental

violations

The project utilized filter

fabric rapped bin blocks and

a stone berm for stock pile

protection.

Using this method provides

stronger protection then

wattles, hay bales, or silt

fence.

This method also needs little

to no maintenance and can

be used in high traffic areas.

The project used an

aerosol can puncturing

system to manage its

can waste.

The system reduced

hazardous waste

Saves $33,000 per 4,400

cans

The project

used self

contained

concrete wash

out systems

These systems

reduce the risk

of an

environmental

violation.

The project required that

all oil spills no matter

volume are reported to

EM.

4 page report done on all

spills.

Inspection of hoses and

equipment daily.

The project used gator grates

to protect their inlets. The

gator grates filter the water

and are easy to clean and

install.

The project also used

multiple protection in areas

of high traffic and disturbed

areas.

CLEAN THE BAY DAY ELIZABETH RIVER CLEAN-UP

Clean the Bay Day

− Annual Clean the Bay Day

− Sponsored by the Chesapeake Bay Foundation, VPA and CSX

− Takes place along the Elizabeth River in Norfolk near Plum Point Park. Volunteers cleaned up along the river, Plum Point Park, ERT, and APM Beach.

− Approximately 3 tons of trash collected

− Approximately 200-250 Volunteers

− 60 - 70 SKW Employees and their Families

Homemade ice cream was made by

SKW’s own Henry Wood, and

Skanska’s own Mr. Gray.

The ice cream was

delicious and enjoyed

by everyone!

The project worked

with the Elizabeth

River Project to make

oyster blocks using

waste concrete from

the project.

Sustainability

The project

recycles or

reuses more than

98% of all its

construction

waste.
