What is the big picture problem?

Long Creek and its tributaries do not meet state water quality standards

Monitoring Summary

The data collected during 2010 and 2011 suggest the following:

– Temperature and dissolved oxygen are major stressors in the upper portion of the watershed. – Chloride is a major stressor in the south and north branches. – Metals and nutrients are stressors throughout the watershed. – Water quantity is a known issue throughout the watershed and is being analyzed further.

Educational Partners

• Service learning projects with

Unity College (Dr. Lois Ongley).

• Street Dust and stream sediment

core sampling/evaluation with University of Southern Maine (Dr. Luci Benedict).

What issues are we addressing?

• Implement non-structural measures

– Chlorides, Metals, Nutrients

• Treat 150 impervious acres

– Volume of water (stream flow), metals, nutrients, dissolved oxygen, temperature

• Implement 10 stream habitat mitigation sites

– Dissolved oxygen, temperature, in-stream habitat, fish passage

Goal: Meet Water Quality Standards by 2020

• Implement non-structural measures

– Vacuum sweeping, catch basin cleaning – Operation & Maintenance Plans – Targeted education – Land use planning & standards promoting LID

• Treat 150 impervious acres

– 26.33 acres treated (18%)

• Implement 10 stream habitat mitigation sites

– 2 completed (20%)

Non-structural - Sweeping

Non-structural – Catch Basin Cleaning

Non-structural – Site/BMP Inspections

• 115 site inspections completed
• Reports will go out to landowners in February

Non-structural measures – Winter Maintenance

• Observe snow storage and revise plans
• Potentially group properties into salt usage areas

Landowner Obligations

• Pay Assessments on time

– Budget for next fiscal year mailed Feb 1 – Next year’s assessments mailed April 1 – Fiscal Year - July 1 – June 30 – Invoicing biannually - January & July

• Provide easements for BMPs in Plan

Landowner Obligations – talk to us!

Tell us when you have plans to …

• Construct new impervious
• Redevelop
• Sell your property
• Resurface pavement
• Change contractors for

winter maintenance or landscaping

Landowner Obligations

• Implement Operation & Maintenance Plans

– Maintenance of BMPs (if you installed it, you maintain it) – Winter maintenance – Landscaping – Vacuum sweeping – Catch basin cleaning – Inspection of BMPs

Areas for Exploration – Coal Tar Sealants

• Coal tar-based sealcoat produces 30 times

more PAHs than no sealcoat.

• PAHs may harm fish and, under some

conditions, pose a risk of cancer to humans.

Areas for Exploration - Chlorides

• Determine what BMPs

should be used

• Porous pavement or

not??

What’s Next?

• Assessment of vacuum sweeping

and catch basin cleaning frequencies

• Further evaluation of chlorides and winter

maintenance practices

• Work with landowners regarding coal tar-

based sealants, winter maintenance and landscaping practices
