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* |
---|---|---|---|
2022 | |||
2021 | Source Reduction - In developing reduction strategies for consideration, Tresca reviewed trade publications and EPA databases, hired an outside technical consultant to examine current operating practices, and solicited employee suggestions regarding toxics use reduction. | ||
2016 |
Barriers: B6-Barriers to P2 B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas
Barriers: B3-Barriers to P2 B3 - Concern that product quality may decline as a result of source reduction. |
Other Environmental Practices - In developing reduction strategies for consideration, Tresca reviewed trade publications and EPA databases, hired and outside technical consultant to examine current operating practices, and solicited employee suggestions regarding toxics use reduction.
Other Barriers to Source Reduction - Tresca has considered 27 alternative admixtures. However, none of the alternative admixtures were selected to be used. The alternative admixtures considered have an increase in a health or physical hazard, would use more nitrate compounds, increased mixing times, decreased the strength of the concrete, had a shorter shelf life, and/or was not economically feasible. In addition, any alternative admixture selected must be Massachusetts Department of Transportation approved. Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - No nitrate compound waste is generated since the admixture is a raw material that is completely incorporated into the final product. The admixture is delivered and stored in bulk and is automatically dispensed, so no residue is generated. Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - Nitrate compounds are contained in the admixture MasterSet AC534. Tresca opted to use MasterSet AC534 because it does not contain added chloride and conforms to the most stringent chloride ion limits required by the concrete industry standards. Added chlorides can potentially initiate or promote the corrosion of reinforced steel. Chloride ion constraints are typically in place for concrete used in coastal environments. Other issues with using an admixture containing chlorides include drying shrinkage, creep, heat evolution, and resistance to sulphate attack. In addition, there is a potential energy savings by using MasterSet AC534 in the manufacture of concrete block by reducing curing temperatures and/or steaming time. |

Other Barriers to Source Reduction - Tresca uses admixtures containing nitrate compounds since they do not contain added chlorine and conform to stringent chloride ion limits required by industry standards. In addition, certain admixtures that contain nitrate compoounds are required by Massachusetts Department of Transportation for their projects. |

2011 | Other Environmental Practices - Tresca uses admixtures containing nitrate compounds since they do not contain added chloride and conform to stringent chloride ion limits required by industry standards. Massachusetts Department of Transportation requires the use of nitrate containing admixtures in certain concrete applications. Tresca has actively participated in Toxic Use Reduction Planning, as required by Massachusetts Department of Environmental Protection. However, no toxic use reduction options are feasible to be implemented. | ||
