Off-site recovery

You must report the location of the POTW in Section 1 in Part II of Form R. Do not report any information about the on-site treatment plant in this section. You are not required to report the location of the off-site, privately owned recovery firm or provide any information concerning off-site recovery because recycling or reuse of toxic chemicals is exempt from reporting. 

Transfers to Other Off-S(te Locations. Yourfacility returns the lead particulate collected by the fabric filters to the off-site smelter for recovery and reuse. You are not required to report releases of listed substances to off-site recovery facilities therefore, no information concerning the off-site smelter should be entered in Part III, Section 6 of Form R. 

Recovery of metals from treatment sludges by off-site commercial plants is an option that is employed at the present time to some extent in California, and that will likely see rapid growth in the near future. Types of off-site recovery services that presently exist in California or elsewhe. in the United States include those offered by smelters, hydrometallurgical plants, and ion exchange/electrolytic recovery plants. 

Recycling (or reuse) refers to the use (or reuse) of materials that would otherwise be disposed of or treated as a waste product. A good example is a rechargeable battery. Wastes that cannot be directly reused may often be recovered on-site through methods such as distillation. When on-site recovery or reuse is not feasible due to quality specifications or the inability to perform recovery on-site, off-site recovery at a permitted commercial recovery facility is often a possibility. Such management techniques are considered secondary to source reduction and should only be used when pollution cannot be prevented. 

Off-sIte recovery. Off-site recovery is preferable when the on-site waste is not available in sufficient amount to make an in-plant recovery system cost-effective. The cost of an off-site recycling process depends upon the purity of the waste and the market for the recovered material. The offsite process is also preferable when this facihty exists for other plants.

Ex situ or off-site, regeneration of base metal catalysts is a service offered by several vendors worldwide, including Catalyst Recovery, Inc., of Lafayette, Louisiana, and Medicine Hat, Alberta, Canada Catalyst Recovery, Europe of Rodange, Luxembourg Nippon CRI of Miyako, Japan Englehard (formerly Edtrol) of Salt Lake City, Utah Eurecat, U.S., of Pasadena, Texas and Eurecat, SA of La Voulte, Erance (22—28). 

In this part of the form, you ara required to list all off-sIte locations to which you transfer wastes containing toxic chemicals. Do not list locations to which products containing toxic chemicals are shipped for sale or distribution in commerce or for further use. Also, do not list locations to which wastes containing chemicals are sold or sent for recovery, recycling, or reuse of the toxic chemicals. The information that you enter in this section relates to data you will report in Part III, Section 6. 

Yourfacility is involved in chrome plating of metal parts, which produces an aqueous plating waste that is treated on-site to recover chromium sludge. The effluent from the on-site treatment plant, which contains chromium compounds (a listed toxic chemical), is piped to a POTW. The chromium sludge is transferred to an off-site, private ly owned firm tor the recovery of the chromium.

Does the computer room have limited access (e.g., are the servers physically/ logically secure) 2. Are there provisions for power backup 3. Is there a disaster recovery plan and is it periodically tested 4. Is there environmental monitoring 5. Are there off-site back-up facilities for key documents and software Is it readily retrievable ... 

The CERCLA reauthorization regards off-site transport and disposal without treatment as the least favored alternative where practicable treatment technologies are available. It also favors the use of permanent solutions and alternative treatment technologies or resource recovery technologies and using them to the maximum extent practicable. 

Similar to the active perimeter gas control system, an active interior gas collection/recovery system consists of gas extraction wells, gas collection headers, vacuum blowers or compressors, and a treatment system. However, it is used to directly remove the hazardous gases from the site (beneath a landfill), instead of off-site removal. Figure 16.9 shows a schematic view of such a system.

The location of the reinjection wells with respect to the recovery well is also an important consideration. Locating the wells too closely can create counterproductive effects. Locating the reinjection wells too far away from the recovery well may significantly reduce the desired effect or eliminate the benefits altogether. If the latter is the case, dead spots may result and may cause short-circuiting of the LNAPL pool hydrocarbon plume. Once this happens, off-site migration of the plume is possible. In fact, reinjection wells placed and spaced improperly can, in some instances, accelerate off-site migration. 

The overall efficiency and effectiveness of LNAPL hydrocarbon recovery programs have also been impacted by other factors. These factors include limitations associated with LNAPL recovery from low-yielding formations, inability to gain access to optimal recovery and off-site locations, coproduced water-handling constraints, and economic constraints.
