Diaz Chemical is a specialty chemical manufacturer located in a residential neighborhood in Holley, New York.
EPA responded to investigate and clean homes and properties that were impacted by the accidental release of 2-chloro-6-fluorophenol (CFP) from the Diaz Chemical facility.
The removal action began with security, daily inspections of drums, tanks and piping, and maintenance of the chemical facility. EPA operations expanded in August 2003, to include the removal of all hazardous substances within drums, tanks and facility piping.
As of August 10, 2007, the site removal actions proposed in the September 2006 Action Memorandum have been completed. The removal action is continuing with the Operation and Maintenance (O&M) phase of the project.
2. The following buildings have been dismantled as of August 10, 2007: Area A, Area D, Boiler Room, Area F, Area R, laboratory, electrical room, Area C, Area E, and Warehouse 4. Debris associated with the dismantling has been accomplished through multiple disposal facilities.
3. All areas where demolition has occurred have been backfilled and graded. During the backfilling actions, a large hand-dug well was discovered in the location of the former boiler room. EPA installed concrete caps and a manhole over the well and the remedial program will evaluate the well as part of their NPL RI/FS implementation.
4. All waste materials from drums, laboratory chemicals, electrical transformers, tanks and reactor vessels have been removed from the site.
5. Warehouse 2 has been completely decontaminated. Residual vapors within the buildings were not detected with field instruments. Due to the porous nature of the building materials, the building was encapsulated with a vapor sealing paint.
6. Warehouse 9, across the street from Diaz, has been cleaned out and is empty, except for a few pieces of decontaminated site equipment and a lamp assembly area not associated with Diaz.
7. Air monitoring for lead and dust particulates have been well within the Site action levels during the dismantling.
8. Of the 139 reactor vessels and tanks that were on-site when EPA assumed the cleanup at the site, all have been decontaminated and sheared for off-site recycling.
9. Since September 2006, the following waste and materials have been sent off-site for disposal or recycling:
- 767 tons of structural steel, motors, and unprepared tank and scrap steel for recycling.
- 1,320 cubic yards of PPE and contaminated debris for landfill disposal.
- 222 drums of bulked carbon for landfill disposal.
- 500 tons of concrete to be recycled.
- 5,250 tons of concrete for landfill disposal.
- 350 drums or various waste groups for disposal off-site, for a total of
8,590 since 2003.
- Removal of 9 PCB transformers for disposal off-site.
- 175 cubic yards of lead contaminated wood for microencapsulation
disposal.
- 39 lead-acid batteries for recycle
- 20 cubic yards of ACM debris for disposal.
10. The groundwater pump and treat system and maintenance of the SPDES permit continue at the site. Sampling results indicate that the system is working effectively.
