Locate such activities away from conveyance channels, storm drain inlets and waterways; Minimize the exposure to precipitation and storm water or use secondary containment structures designed to eliminate the potential for spills or leaked chemicals

Washout of Applicators/Containers used for Paint, Concrete, and Other Materials

Direct all concrete, paint, and washout activities into a lined, water-tight container or pit to ensure there is no discharge into the underlying soil and surrounding areas

Concrete Slurry is a Pollutant

• Concrete Slurry From Pouring & Sawcutting Pollutes Stormwater With High pH

• Do Not Allow Slurry to Mix With Stormwater

• If Slurry Mixes With Stormwater Then Treat With Dry Ice or CO2 Sparging

• Concrete Clean Up Should Be Done Only in Formed Areas

• Unused Concrete Should Be Returned for Recycling

Page 19: Prohibited Discharges

Concrete Handling

• Concrete contributes turbidity and High pH

• Return unused concrete to plant

• Wash chutes, pumps, hand tools into a contained area

BMP WA C-151 OR NS-14 AK-24

Designate areas to be used for washout

A person must not suffer or permit the discharge or washing of cement or concrete during the construction of exposed aggregate driveways, patios, or from concrete vehicles or equipment.

Bylaw No.3447, 2001

Page 21: Prohibited Discharges

For concrete washout areas, remove hardened concrete waste when it has reached ½ the height of the container or pit

Permanent Storm Water Management Control

When a project constructs, alters, installs, modifies, or operates any part of a permanent storm water management control at a site submit a copy of the engineering plans for review.

Winter Shutdown

Identify the anticipated dates of fall freeze-up and spring thaw for their site and plan for winter shutdown. •Frozen ground by itself is not considered stabilization. Provide for : •Stabilization of conveyance channels; disturbed slopes, disturbed soils, and soil stockpiles. •Erosion and sediment control measures in anticipation of spring thaw.

Page 30: Prohibited Discharges

Winter Construction May be better suited for the construction of ice roads or the placement of sand or gravel on frozen tundra with no excavation or potential to pollute waters.

Page 31: Prohibited Discharges

If the cutting occurs after the onset of spring thaw , or above freezing temperatures that cause melting of snow, then precautions must be taken to protect the environment prior to such clearing.

Late Winter Clearing Cutting of trees and brush while the ground is frozen, without disturbing the vegetative mat, may be beneficial.

Maintain BMPs

All BMP’S Have Designed Performance Goals & Standards

All BMPs Should Have the Performance Goals Detailed

Page 33: Prohibited Discharges

Maintain all control measures, good housekeeping measures, and other protective measures in effective operating condition.

North Pole

Page 34: Prohibited Discharges

If site inspections identify control measures, good housekeeping measures, or other protective measures that are not operating effectively, implement corrective actions ASAP.

Ketchikan

Page 35: Prohibited Discharges

If existing control measures need to be modified or if additional control measures are necessary for any reason, complete any corrective action as soon as possible.

Within 7 days

Page 36: Prohibited Discharges

Remove sediment from silt fences, check dams, berms or other controls before the accumulated sediment reaches one-half (½) the distance up the above-ground height (or it reaches a lower height based on manufacturer’s specifications) of the control measure. For sediment traps or sediment ponds, remove accumulated sediment when the design capacity has been reduced by fifty (50%) percent. Anchorage

MAINTAIN BMPs

• All BMPs require maintenance

• Proper installation is only the first step

• Inspect on a regular basis and after every discharge

• Designate a person to inspect E & S controls

Page 38: Prohibited Discharges

Maintenance of Controls

•Summarize routine maintenance of BMPs. •Include schedules (daily, weekly, etc.) as well as who is responsible. •Detail maintenance procedures for individual BMPs. •All maintenance activities must be documented.

Page 39: Prohibited Discharges

BMP’s Need More Than “On The Fly” Maintenance

Page 40: Prohibited Discharges

Some BMPs in Certain Situations are Harder to Maintain Than Others

Page 41: Prohibited Discharges

Timely Monitoring of BMPs is Required and prudent

• Responsible Person Must Inspect & Record BMP Performance

• BMP Performance Must be Inspected per all Permit Conditions

• Schedule time for inspections

Page 42: Prohibited Discharges

BMP Inspections

• Qualified Inspectors Must Fill Out Inspection Checklists/Reports

• You Must Record BMP Maintenance

• You Must Record any Sampling Data of Stormwater Discharge

Its about how you do,

what you do,

and when you do it
