• to harm local or regional biological communities, and, if so, have capture and reuse of these resources been explored?

Facility Matrix Element 3,2

Facility Activity: Principal Business Activity—Processes Environmental Concern: Energy Use

• Have all process materials been evaluated to ensure that they use as little energy as possible?
• Are processes monitored and maintained on a regular basis to ensure that they retain their energy efficiency as designed?
• Do process equipment specifications and standards require the use of energy-efficient components and subassemblies?

Facility Matrix Element 3,3

Facility Activity: Principal Business Activity—Processes Environmental Concern: Solid Residues

• Are processes designed to generate minimal and nontoxic solid residues?
• Where solid materials are used as process inputs, have attempts been made to use recycled materials?
• Are processes designed to produce usable by-products, rather than byproducts suitable only for disposal?

Facility Matrix Element 3,4

Facility Activity: Principal Business Activity—Processes Environmental Concern: Liquid Residues

• Are processes designed to generate minimal and nontoxic liquid residues?
• Where liquid materials are used as process inputs, have attempts been made to use recycled materials?
• Are pumps, valves, and pipes inspected regularly to minimize leaks?

Facility Matrix Element 3,5

Facility Activity: Principal Business Activity—Processes Environmental Concern: Gaseous Residues

• Are processes designed to generate minimal and nontoxic gaseous residues?
• Are processes designed to avoid the production and release of odorants?
• If volatile organic compounds are utilized in any processes, are they selected so that any releases will have minimal photochemical smog impact?
• If greenhouse gases, particulates, or nitrogen or sulfur oxides are generated, are they captured and have less environmentally harmful options been evaluated?
