Other Barriers to Source Reduction - This chemical occurs as an impurity in the asphalt cement binder which is beyond our control to mitigate. Other Environmental Practices: Recycling - This plant used 13,900 tons of reclaimed asphalt pavement materials which saved them from being disposed in a landfill. |

Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.

Other Environmental Practices: Recycling - This plant used 23,883 tons of reclaimed asphalt paving materials which saved them from being disposed in a landfill. Barriers to P2: B7 - No known substitutes or alternative technologies. - This chemical occurs as an impurity in the asphalt cement binder which is beyond our control to mitigate. |

Other Barriers to Source Reduction - This chemical occurs as an impurity in the asphalt cement binder which is beyond our control to mitigate. Other Environmental Practices: Recycling - This plant used 17,182 tons of reclaimed asphalt paving materials which saved them from being disposed in a landfill. |

Other Barriers to Source Reduction - Even though we have to report Benzo(g,h,i)perylene because of the "contained-in" requirement, the Benzo(g,h,i)perylene that is released to the environment via the stack is due to fuel combustion (the asphalt binder and exhaust gas do not come in contact with each other). The burner is tuned up every year to maximize combustion efficiency, which keeps emissions low. Other Environmental Practices: Recycling - The source recycled 63,717 tons of reclaimed asphalt pavement removed from existing roadways into new asphalt pavement materials. |

| 2016 | Source Reduction - Even though we have to report Benzo(g,h,i)perylene because of the "contained-in" requirement, the Benzo(g,h,i)perylene that is released to the environment via the stack is due to fuel combustion (the asphalt binder and exhaust gas do not come in contact with each other). The primary fuel burned in the plant was changed from fuel oil to propane, which is more environmentally friendly. The burner is tuned up every year to maximize combustion efficiency, which keeps emissions low. | ||

Other Barriers to Source Reduction - The toxic compound is an impurity in the Asphalt Cement binder that occurs naturally and is a function of the source of the crude oil and the refinery where the crude oil was processed. All of which occur before the Asphalt Cement is delivered to the facility. |

Other Barriers to Source Reduction - Benzo(g,h,i)perylene is an inherent impurity in the raw material used to manufacture Asphalt Paving Materials. The raw materials do not become a waste, therefore there is no need for source reduction activities. |

The Waste Management Hierarchy |
The waste management hierarchy established by the Pollution Prevention Act (PPA) guides waste generators toward the best options for managing wastes.
The preferred option is to prevent pollution at its source, but for waste that is generated, the preferred management methods are recycling, followed
by burning for energy recovery, treatment and, as a last resort, disposing of the waste.

- A breakdown of production-related waste managed. This includes all amounts of the chemical released directly to the environment or otherwise managed as waste, other than waste generated by one-time events not associated with normal production processes (e.g., fires or remedial actions).
- A production ratio or activity index to provide context for reported toxic chemical quantities. For example, if a chemical is used in the manufacture of refrigerators, the production index would track the number of refrigerators produced and could be used to help gauge how much of the chemical is being released per unit of production.
- Any newly implemented source reduction activities, reported using "W-codes" (e.g., "W41: Increased purity of raw materials")
