important considerations
Important Considerations
  • The new permit

    • Requires a commitment of capital and staff resources beyond recent levels
    • If implemented carefully, will result in improved water quality conditions in County waterways
today s discussion
Today’s Discussion
  • Staff’s understanding of requirements
  • Many options to meet requirements
  • Does not address programs managed outside the Stormwater Division
implementation goals
Implementation Goals
  • Comply with State and Federal law
  • Be cost effective
  • Spend funds meaningfully
  • Meet citizens expectations
    • Keep costs down
    • High quality environment & clean water
  • Build on existing County programs
tmdl action plans new
TMDL Action Plans - New
  • Must develop two – Skiffes Creek and combined Mill-Powhatan Creeks
  • Bacteria is the biggest water quality problem in the County other than sediment
  • Good baseline information for the Mill-Powhatan Creeks
  • Must include an end date
tmdl action plans ideas
TMDL Action Plans - Ideas
  • Begin with a watershed management plan for Skiffes Creek
    • Quantify pollutant reductions
    • prioritize retrofit options
  • Consider targeted septic system connection program for FY17 onward
cbtmdl action plan new
CBTMDL Action Plan - New
  • Must meet the DEQ Guidance Memo
  • Uncertainty regarding scale of MS4
  • Good baseline information in the Mill, Powhatan and Yarmouth Creeks Watershed Plans
  • Must achieve 5% reduction in N, P and S loads by June 30, 2018
cbtmdl action plan ideas
CBTMDL Action Plan-Ideas
  • Begin with a watershed management plan for College Creek (in addition to Skiffes Creek)
    • Quantify pollutant reductions
    • prioritize retrofit options
  • New program area – will need help developing, implementing & tracking plan
action plans and cip
Action Plans and CIP
  • Capital Improvement Program
    • new treatment facilities on County facilities
  • Capital Maintenance Program
    • Upgrades to County treatment facilities
  • Invest in publically owned property first
  • Won’t have complete picture until Action Plans are complete in FY15 & FY16
public education outreach
Public Education/Outreach
  • Focus on “Clean Water Heritage”
  • Coordination with HRPDC
    • Printed materials and website
  • Use direct mail to target specific audiences
  • Increasing reach from 3% to 20% will be difficult
public involvement and participation
Public Involvement and Participation
  • Current program fully meets the new requirements
  • Keep doing what we are doing
    • Volunteer water quality monitoring program
    • Stormwater Program Advisory Committee
    • Partnerships with Master Gardeners, Master Naturalists
illicit discharge detection elimination
Illicit Discharge-Detection, Elimination
  • Larger urbanized area = more outfalls
  • More outfalls = more mapping & field investigations to perform/track
  • Mapping is time intensive, requires high degree of GIS capability, must be field verified
illicit discharge detection elimination ideas
Illicit Discharge-Detection, Elimination - Ideas
  • Consider a consultant to map MS4 outfalls, drainage areas and field verify
    • Once per permit effort
  • Consider efficiencies in developing and managing field investigations and follow-up
    • Improved equipment/software
post construction stormwater management
Post-Construction Stormwater Management
  • Inspection cycles
    • private facilities once every 5 years
    • Public facilities annually
  • Consistency & efficiency
  • Inspection process very paper-heavy
  • New emphasis on enforcement - may need new ordinance language
post construction stormwater management ideas
Post-Construction Stormwater Management - Ideas
  • Develop operations & maintenance manual for County facilities
  • Consider a web-based GIS interface for staff access to records in the field
  • Look for efficiencies to provide more office support (GIS/mapping) to staff
pollution prevention good housekeeping
Pollution Prevention-Good Housekeeping
  • Most MS4 fines result from Pollution Prevention problems
  • Requirement needs the most effort
    • Must develop & implement a biennial training program
    • Must implement regular facility spot checks
pollution prevention good housekeeping ideas
Pollution Prevention-Good Housekeeping - Ideas
    • Consider a County-wide Pollution Prevention Team crossing agency lines
  • Consider consultants to provide specialized training
  • Will need all parts of organization to participate
in summary
In Summary
  • The new permit
    • Requires more effort than previous permits
    • Requires a commitment of capital and staff resources beyond recent levels
    • If implemented carefully, will result in improved water quality conditions for County citizens
