Waste Management Comparison - 2015
Pollution Prevention Activities for Selected Chemical
| Reporting Year | Section 8.10: Newly Implemented Source Reduction Activity | Section 8.10: Methods to Identify Activity | Section 8.11: Optional Pollution Prevention Information* |
|---|---|---|---|
| 2021 |
Source Reduction:: S41: Improved scheduling, record keeping, or procedures for operations, cleaning, and maintenance
|
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
|
S41: Internal audits emphasize pollution control (baghouse) maintenance. Improvement in recordkeeping and operational efficiency monitoring equipment in place. Source Reduction - Internal audits emphasize pollution control (baghouse) maintenance. Improvement in recordkeeping and operational efficiency monitoring equipment in place. |
| 2020 |
Source Reduction:: W19: Other changes in operating practices
|
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
|
W19: Internal audits emphasize pollution control (baghouse) maintenance. Improvement in recordkeeping and operational efficiency monitoring equipment in place. Source Reduction - Internal audits emphasize pollution control (baghouse) maintenance. Improvement in recordkeeping and operational efficiency monitoring equipment in place. Other Environmental Practices: Recycling - Concrete waste materials from "come-back" loads or mixer residuals are collected onsite and subsequently sent to an offsite recycle crusher for re-use. This recycling and reuse thereby reduces the quantity that would otherwise be transferred offsite for disposal. |
| 2015 |
Source Reduction:: W13: Improved maintenance scheduling, recordkeeping, or procedures
|
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
|
W13: Improved maintenance and inspection have ensured pollution control systems are maintained and capturing air released form ready mix production. |
| 2014 |
Source Reduction:: W13: Improved maintenance scheduling, recordkeeping, or procedures
|
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
|
W13: Internal audits put increased pressure on pollution control (baghouse) maintenance. Improved record keeping, and installation of pressure gauges was also instituted. |

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")
