| 2018 |
Barriers: B3-Barriers to P2 B3 - Concern that product quality may decline as a result of source reduction.
|
Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - Phenol provides performance characteristics that are important to product performance in some cases; we have reformulated products to reduce phenol levels where feasible |
|
| 2017 |
Other Environmental Practices: Recycling - Use of St. Mary's cement as a beneficial reuse option for scrap sand was discontinued in late 2017 due to facility closure |
||
| 2016 |
Barriers: B6-Barriers to P2 B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas
|
Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - We were focused on other priorities this year. |
|
| 2015 |
Barriers: B6-No Information B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas
|
Other Environmental Practices: Recycling - We greatly increased our shipments of scrap sand to St. Mary's Cement for beneficial reuse. This sand is an excellent feedstock for cement production, being silica sand. The resin coating is thoroughly destroyed in the cement kiln. |
|
| 2014 |
Source Reduction:: W58: Other process modifications[-5-14%]
Source Reduction:: W82: Modified design or composition of product[-15-24%] |
Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program)
Methods to Identify SR Opportunities: T04: Participative team management |
Source Reduction - We increased the rate of scrubber solution blow down for the first 6-months of the year to increase the removal efficiency for formaldehyde, phenol, and VOC. Other Environmental Practices - In 2014 the facility installed oxidizers on two of its three production lines. The oxidizers were operational for approximately the second 6-months of 2014, and will be operated continually (during production) in the future. The oxidizer systems are designed to achieve 99% total destruction efficiency for VOC and HAP's emitted by the production process. |
| 2013 |
Other Environmental Practices - The facility is installing two thermal oxidizers to control onsite releases of phenol and other organic compounds. The devices will be operational in August 2014.
Other Barriers to Source Reduction - Pursued end of pipe controls |

Source Reduction - The facility expanded its use of resins with low free phenol levels in 2009. The faiclity redesigned many of its foundry products to enable use of low free phenol resins. Non-routine disposal of 380 lb to Badger Disposal was product returned for evaluation under reverse distribution; this product was produced at a different facility (a toll producer). |
| 2008 |
Source Reduction:: W42: Substituted raw materials
|
Methods to Identify SR Opportunities: T06: Employee recommendation (under a formal company program)
|
Source Reduction - Implemented a major program to reduce the amount of free phenol in the resins used to produce resin-coated sands for the foundry industry, which will result in significantly lower emissions and waste transfers from our site, and lower emissions at customer sites. We worked with our supplier to install new equipment at their resin production plant to allow production of low-phenol resins in an economic manner. We reformulated most of our foundry products to use the new, low-phenol formulations. We are currently converting to the low pheonol resins. This conversion process will be ongoing until roughly July 2010. |

TRI Pollution Prevention Glossary
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")
