CALGreen Section: 5.408. 1 Construction waste management. Recycle and/or salvage for reuse a minimum of 50 percent of the non-hazardous construction waste in accordance with Section 5.408.1.1, 5.408.1.2 or 5.408.1.3; or meet a local construction and demolition waste management ordinance, whichever is more stringent.
5.408.1.1 Construction waste management plan. Where a local jurisdiction does not have a construction and demolition waste management ordinance that is more stringent, submit a construction waste management plan that:
1. Identifies the construction waste materials to be diverted from disposal by efficient usage, recycling, reuse on the project, or salvage for future use or sale.
2. Determines if construction waste materials will be sorted on-site (source-separated) or bulk mixed (single stream).
3. Identifies diversion facilities where construction waste material collected will be taken.
4. Specifies that the amount of construction waste materials diverted shall be calculated by weight or volume, but not by both.
5.408.1.2 Waste management company. Utilize a waste management company that can provide verifiable documentation that the percentage of construction waste material diverted from the landfill complies with this section.
Note: The owner or contractor shall make the determination if the construction waste material will be diverted by a waste management company.
Exceptions to 5.408.1.1 and 5.408.1.2:
1. Excavated soil and land-clearing debris
2. Alternate waste reduction methods developed by working with local agencies if diversion or recycle facilities capable of compliance with this item do not exist.
3. Demolition waste meeting local ordinance or calculated in consideration of local recycling facilities and markets, where demolition of an existing structure(s) is necessary for the
construction of a new structure.
5.408.1.3 Waste stream reduction alternative. The combined weight of new construction disposal that does not exceed 2 lbs/s.f. of building area may be deemed to meet the 50% minimum requirement as approved by the enforcing agency.
5.408.1.4 Documentation. Documentation shall be provided to the enforcing agency which demonstrates compliance with Section 5.408.1.1 through 5.408.1.3. The waste management plan shall be updated as necessary and shall be accessible during construction for examination by the enforcing agency.
Notes:
1. Sample forms found in “A Guide to the California Green Building Standards Code (Nonresidential)” located at: http://www.bsc.ca.gov/CALGreen/default.htm may be used to assist in documenting compliance with the waste management plan.
2. Mixed construction and demolition debris (C&D) processors can be located at the
CaliforniaDepartment of Resources Recycling and Recovery (CalRecycle).
5.408.2 Isolated jobsites. The enforcing agency may make exceptions to the requirements of this section when jobsites are located in areas beyond the haul boundaries of the diversion facility.
Intent:
Since construction waste makes up about 27% of the waste stream inCalifornia, this code provision is reducing the amount of construction waste from new construction that would be
sent to the landfills, thereby extending the life of the landfills. Its purpose is also to
encourage material resource efficiency through re-use and recycling of construction waste products.
Change for 2012: CBSC is proposing combining three sections into one, 5.408.1 Construction waste management, to provide clarity to the code user. Terms are being
coordinated to mean the same things. Options for utilization of an approved waste management company and a waste stream reduction alternative for efficient construction methods are added to provide more methods of compliance. Exceptions are broadened to recognize that 50% of demolition waste may not be recyclable locally.
Existing Law or Regulation:
AB 939 (Stats. 1989, c. 1095) mandated a 50% diversion of all waste by 2000, but the
CALGreen regulation targets 50% of new construction waste that makes up a smaller percentage of the total waste stream. There are some local jurisdictions that have ordinances in place that have requirements for this provision.
Compliance Method:
1. Determine if a local construction waste management ordinance is in place in your jurisdiction and comply with the more stringent requirement
2. Determine what local hauling and recycling facilities are available in your area to establish the most economically feasible option for recycle and/or salvage of construction debris. If there is no facilities in your area, use Exception 2 and work with the local enforcing agency to establish an acceptable alternate.
3. If applicable to the project, e.g., where walls are framed off-site or panelized wall systems are employed that reduce site waste significantly, the waste stream alternative may be appropriate. Document the weight of total waste compared to the building area, which may considered the gross square footage of each floor and the roof as approved by the enforcing agency.
4. Include for recycling the following materials: carpet, wood, aggregate, paint, shingles, wallboard or any other materials that have recyclable value. For more information on various materials visit the C&D Publications link on the CALRecycle website, the Construction Waste Management (CWM) Worksheet provided in Part 4 of this Guide, or as required by local ordinance.
Note: The demolition debris provision may be applicable in the CALGreen code if an EXISTING building is going to be completely torn down and a NEW building built on the same site, where both are considered to be part of the same project. This would be determined on a case by case basis. Local market conditions may determine the level of diversion of demolition debris acceptable to the local enforcing agency.
Enforcement:
Plan Intake: The reviewer and/or plan checker should review the plans, specifications and/or forms to confirm that a construction waste management plan has been included with the plan submittal or that and Exception 2 has been approved by the enforcing agency.
On-Site Enforcement: The inspector should review the approved construction waste management plan or Exception 2 to verify that the plan is being followed or that an exception is being used. The inspector may ask for haul tags and/or reports from the contractor to verify compliance with the 50 percent waste reduction. Verification by documentation from a waste management company or recycling facility is acceptable.
Suggestion: Building departments are strongly urged to work with their jurisdictions’ Recycling Coordinators to determine if local conditions warrant exemptions and to identify appropriate means of alternate compliance.
CALGreen Section: 5.713.8.1 Construction waste management. For additions and remodels recycle and/or salvage for reuse a minimum of 50 percent of the non-hazardous construction waste in accordance with Section 5.713.8.1.1 or 5.713.8.1.2; or meet a local construction and demolition waste management ordinance, whichever is more stringent.
[The provision in Division 5.4 for a waste stream alternative is eliminated from this subsection, with the balance of subsections unchanged from those in Division 5.4]
Intent:
The intent of this measure is to ensure that construction waste is diverted away from landfills and re-used or recycled at a rate of at least 50% of total construction waster, either in conformance
with local ordinance, a construction Waste Management Plan (WMP) or utilization of a waste management company certifying to a 50% diversion.
Change for 2012: CBSC adopted this section and subsections as modified for the new construction division, to provide clarity to the code user. The pounds-per-square-foot alternative is not included here, because more demolition waste is expected with additions or alterations than with new construction; however, there is more potential for reuse of materials. Other than that, this proposal recognizes that waste generated from additions and alterations should be recycled at the same rate as for new construction. The exception for demolition debris is maintained for those circumstances where, due to local facilities and markets, demolition may be recycled at other than a 50% rate.
Compliance and Enforcement: See § 5.408.1 and subsections of this guide
