The following Best Practices are designed as directives for Construction and Demolition Contractors working for Middlebury College as well as for the staff of the college. These Best Practices ensure that hazardous and non-hazardous waste generated from demolition and construction of buildings on the Middlebury College Campus are managed to reflect the commitments outlined below by the Middlebury College Board of Trustees.
Commitments from Board of Trustees
Middlebury College as a liberal arts institution is committed to environmental mindfulness and stewardship in all its activities. This commitment arises from a sense of concerned citizenship and moral duty and from a desire to teach and lead by example. The College gives a high priority to integrating environmental awareness and responsibility into the daily life of the institution. Respect and care for the environment, sustainable living, and inter-generational responsibility are among the fundamental values that guide planning, decision making, and procedures. All individuals in this academic community have personal responsibility for the way their actions affect the local and global environment.
--adopted by the Middlebury College Board of Trustees, 1995
Whereas it is the College's intent to make sound decisions regarding construction, renovation and the landscape of the campus in order to achieve the best results and final products, it is therefore resolved that the College shall develop a Framework to implement Procedures and Practices that establish a more informed process in which to review alternatives and provide direction.
-- excerpted from the Guiding Principles for Responsible Building
It is resolved that through that Framework, the College and its appointees shall consider: energy systems, life cycles, water use, scale and location, light pollution, recycling and waste management, materials, community and product sources, community and regional impacts, transportation, aesthetics, indoor air quality, construction site management, viewsheds, open space and other issues related to the campus.
--adopted by the Middlebury College Board of Trustees, 1999
Best Practices for Campus Construction and Demolition
The following practices are intended to provide an overall framework for Construction & Demolition (C&D) waste management at Middlebury College. Individual projects will require specific directives regarding waste material. These specifics will be provided by the college to the contractor on a project by project basis. These specifics will be established prior to the bidding process and will be included in project specifications as well as in contracts with general contractors and sub-contractors. All contractors will be expected to uphold this commitment to waste management to support the college's overall mission in this area.
Practice 1: Pre-Demolition Audit (if necessary)
An audit will be conducted by staff of the college (and a hired contractor if necessary) prior to any demolition project. All materials within a site will be documented by both location (floor plan) and quantities. It will be determined through the audit whether any materials may be reused by architecture salvage operations, the college or private citizens. A walk through inspection will include someone with "salvage/reuse" expertise who understands the value and market for architectural and other salvage materials. At this time, it is necessary to assess the need for a hazardous waste abatement plan. If a plan is determined to be necessary, the section on hazardous waste in this document lays out the best practices for hazardous waste abatement.
The following questions will be used as a step-by-step guide for the pre-demolition audit. A plan will then be approved by college staff and communicated to all contractors:
- What can be re-used (reclaimed) right on site for new construction, i.e asphalt, glass, landscaping materials?
- Are there items of value to community, staff, alumni?
- Are there items (furniture, fixtures, moldings, mechanical equipment, etc.) which have immediate value to a secondary market?
- Are there hazardous wastes on site, i.e. is an abatement plan necessary?
Practice 2: C&D Waste Management by Material
At the onset and as needed (preferably again at the mid-point and at the end) during any C&D project at the college, a series of meetings will be held with Addison County Solid Waste District, college officials and all contractors to review expectations, rules and regulations which must be followed. A review of the consequences (Described in Practice 6) will also be included at these meetings.
Best Practices for Hazardous Waste Management
Practice 3: Abatement Plan
Should any contractor encounter hazardous waste during a project, a college official must be contacted immediately to ensure material is handled properly. Hazardous waste abatement contractors are hired for abatement of hazardous wastes by the college. The practice will include multiple sweeps of the site for removal of materials. College staff will participate to ensure hazardous materials are not overlooked that may be improperly labeled or located somewhere out of sight. Abatement contractors will be subject to the same quality control practices as outlined in the section on Quality Control and Consequences that applies to all C&D projects.
Practice 4: Hazardous Wastes accepted by ACSWD
The following lists makes explicit what is accepted by the local solid waste district and what is not. The list is updated periodically. The college and its contractors are ultimately responsible for the correct disposal of these materials. Non-compliance will result in consequences outlined in the section on Quality Control Best Practices that applies to all C&D projects.
Materials forbidden in trash, metal or C&D loads brought to the Addison County Solid Waste District Transfer Station:
Free-flowing liquids of any kind; Latex or oil-based paint, liquid or dried (truly dried latex can be landfilled); Paint-related products such as thinner or additive; Pesticides; Cleaning Chemicals, liquid or solid; Pool Chemicals, liquid or solid; Industrial/contractor-related chemicals including solvents, coatings, tars and adhesives; Federally-listed hazardous wastes; Friable asbestos; Automotive chemicals (i.e. brake fluid, etc.).
The following materials are accepted at Addison County Solid Waste Management District transfer station if separated:
Batteries, automotive and household; Motor oil; Empty pressurized cylinders (i.e. propane, welding gases); Fluorescent light bulbs or fixtures containing PCB ballasts; Mercury-containing thermostats, thermometers, barometers; Appliances (charge of $3 per item - delivered separately); Non-friable asbestos (additional fee and proper packaging); Tires.
Quality Control Best Practices
Practice 5: Contractor Accountability
At the onset of a C&D project, the contractor is required to issue a plan for handling materials outlined in Practice #2, as well as hazardous materials to be used on site. The plan will include:
List of Use(s)
Materials Safety Data Sheets (if required)
Storage on site
Disposal plan/clean up at end
Documentation of proper management and disposal of all materials including hazardous is required before any payments will be released to contractors.
Practice 6: Consequences
Failure to adhere to the practices outlined in this document will result in the following fines (as appears in contract):
- $1,000 per incident fined by Middlebury College
- Additional fines levied by outside parties (i.e. Addison County Solid Waste District, Clean Harbors, State of Vermont)
- Cost of any cleanup plus 15%
