Hillsboroughs CD Program

• Hillsborough adopted a CD Resolution in 1999 and
  a CD Ordinance in December 2001. Key features
  include

• Building and demo permits require a Waste
  Reduction Plan (WRP). Separate plans are required
  for house demolition and new construction.
• No specific diversion requirement. Building
  Official or designee must approve Waste Reduction
  Plan.
• Must use an approved debris box company and mixed
  debris processing facility. The Town has
  non-exclusive performance agreements regarding
  handling of mixed debris. (Source separated
  materials can go to any recycling facility.)

7
Hillsboroughs CD Program

• Ordinance features (continued)

• A Diversion Summary Report is required prior to
  final inspection. Weight tickets and salvage
  receipts must be submitted.
• The Waste Reduction Plan and the Diversion
  Summary Report must correlate. The before and
  after pictures are compared.

  assessed
• for

• Demolition or construction activities performed

Hillsboroughs CD Program

• Program features

• Fully funded CD Recycling Specialist position
  (through MSW collection fees).

• Recycling Specialist engages the permit applicant
  early in the process.

12
Hillsboroughs CD Program

• Program features (cont.)

• Emphasis on promoting highest and best use of
  materials 1) deconstruction, 2) source
  separation, 3) mixed debris.
• ADC does not count as diversion.
• Largest focus on largest projects (WRP vs. Short
  Form).
• Project and program diversion tracking.

Over 1,400 new home, demolition or major remodel
construction projects have submitted WRPs and
documented diversion from landfills.
13
Hillsboroughs CD Program

• The impacts
• 86 average diversion of CD materials (excluding
  ADC).
• At least 58,000 tons (250,000 cubic yards) of
  documented CD material diverted (Long Form).
• Thousands of other smaller projects (e.g.,
  bathroom

remodels) educated but not quantified (Short
Form).
250,000 cubic yards of debris piled onto an NFL
football field, including both end zones, would
stand 120 feet tall or over 10 stories high.
14
Hillsboroughs CD Program

• Project tracking and permitting

• The Town has integrated the CD program into the
  CRW permit system at critical review and
  inspection touch points. An ordinance-covered
  project cannot receive
• Building/demolition permit prior to having an
  approved WRP(s).
• Final inspection prior to submittal and review of
  the Diversion Summary Report and weight tickets.
• Best to integrate CD project tracking and
  reporting features during building permit system
  design phase.
