Remediation equipment

At Site I, the prime contractor s SSAHP required daily site inspections, the documentation of safety and health deficiencies, and the abatement of deficiencies. Records of site deficiencies, however, were kept intermittently, and hazard abatement was not documented. The subcontractor s SSAHP did not address site inspections and hazard abatement, but its TSCA permit application included requirements for site inspections. Inspection documentation, however, was not available on site, and the site manager was unaware of these written requirements. The site manager did, however, indicate that he conducted site inspections using a mental checklist and that he conducted inspections of remediation equipment before each use. 

Control of site equipment is always important for safety and operational concerns. Many sites are remote or not staffed on a daily basis. Remediation equipment should be fitted with failsafe systems to shut down the system in the event of failure, fire, or unusual conditions (such as injection well plugging). Alarm systems should be included, which may be as simple as illuminating a warning hght, or as complex as a teleconnection to a remote computer station or telephone alert to the operator s residence. Many commercial companies offer remote monitoring equipment. 

In all, 11 vertical soil vapor extraction wells and 9 vertical air sparge wells were installed in the treatment area. Sand chimneys (boreholes filled with coarse sand) were also installed to facilitate vertical air circulation. Mechanical remediation equipment and systems control installed for remediation were mosdy automated with minimal operator control required. 

Another cost estimate placed the total remediation costs at 253,000. This included 64,000 for planning, organization, project management, and remediation equipment 44,000 for field work 74,000 for laboratory analytical work 29,000 for drilling costs and 42,000 for activated carbon and regeneration (D22531A, p. 22). 

Farms, ranches, and feedlots provide food but often are major sources of pollution. Modern feedlots store sewage in lagoons where solids can be collected. Effluent water from lagoons often contains microorganisms that serve as food in fish farms, and solids from the lagoons can be processed into fertilizer. The effectiveness of these operations is often determined by the size of the operation and the need for cleanup. Larger operations can afford more complex remediation equipment and tend to be more cost-effective than small ones. Most large feedlots are located away from population centers whose residents often complain of the odors. 

Remediation time is dependent on the nature, concentration, and extent of the pollution and the capacity of the remediation equipment. More extensive polluted sites are cleaned up in sections. Cleanup duration varies from a few months to several years. 

Remediation Equipment An installation for ER consists of an electrical power unit, an electrolyte management unit, and, optionally, an electrolyte treatment unit and an EnViroCell. All the equipment is built into separate containers that are each 20 ft long. 

Retrospective maintenance to repair or remedy equipment, including computer systems. 

Before any remedial or preventive actions are implemented, an evaluation should be conducted as to appHcabiUty to the specific plant. The evaluation should continue while the actions are in progress. The main action should be to take measures to reduce the ingress of contaminants into the steam generator by using more rehable materials, such as in the condenser tubes, to reduce leakage. Contaminant control equipment, such as full-flow condensate deminerali2ers, should also be employed. 

Assistance in problem definition and in developing a test program should be sought from persons experienced in the field. If your organization has a consultant in separations of this land, by all means m e use of the expertise available. If not, it may be wise to employ an outside consultant, whose special knowledge and guidance can save time, money, and headaches. It is important to do this early after the separation equipment has been installed, there is httle a consultant can do to remedy the sometimes disastrous effects of a poor selection. Often it is best to work with established equipment manufacturers throughout the selection process, unless the problem is unusually sensitive or confidential. Their experience with problems similar to yours may be most helpful and avoid many false starts. 

Two approaches exist to gain control of this factor altering the environment and isolating the metal from the environment. These are remedial measures and can be implemented during or after installation of the equipment. 

The assessor should also find out whether an effective testing program is in place to help ensure the serviceability of process measurement equipment. The successful toller should have an established calibration program to address the accuracy of critical measurement equipment. Safety critical process parameters should be monitored and critical process equipment should automatically interlock when monitoring instrumentation detects safety critical deviations. Interlocks should either facilitate a remedy to the critical deviation or bring the process to the zero energy state. These instruments and interlocking devices should be routinely tested to ensure operational reliability. 

With these definitions in mind, a systematic classification has been made. The various types of embrittlement found in refineries and petrochemical plant equipment, susceptible steels, basic causes, and common remedies are listed in the accompanying table.

With few exceptions, treatment technologies are limited to some extent by the size of the material that they are able to process. These limitations can apply to the throat of the feed devices, the inner workings of the equipment, the treatment mechanisms, or the process elements. To make these remedial technologies efficient and cost effective, separation techniques are used to make the feed stream uniform... 

Personnel and equipment need to be decontaminated in the CRZ. However, the CRZ might be a small area immediately adjacent to the remediation area, which workers are aware of, and is also marked appropriately. Although the CRZ is less formal and likely does not have many decontamination stations, efforts should be made to make sure that personnel and equipment are appropriately cleaned. Many times, due to the logistics of a smaller job, disposal of wastes becomes difficult. If purge water is drummed and left on the site, it is imperative that it is identified, labeled properly, recorded in the site log, and disposed of in the proper manner (in accordance with applicable, local, state, federal, or other regulations). 

Remediation aetivities ineluded site mobilization (i.e., installation of trailers, utilities, and equipment elearing and grubbing grading roads and eonstruetion of deeontamination faeilities, drainage pump stations, and a water treatment system), soil exeavation, thermal proeessing of 7,700 eubie yards of soil, baekfilling and regrading the exeavated area, and site demobilization. 

Six of the eleven sites evaluated (Sites A, B, F, G, I, and K) identified generie remediation hazards in their SSAHPs but did not address the hazards assoeiated with site- and operation-speeifie tasks. For example, the SSAHP for Site B broadly deseribed hazards sueh as the potential for inhalation, ingestion, eontaet, and absorption of eontaminants or heavy equipment and general eonstruetion hazards. The plan did not deseribe speeifie hazards (i.e., levels of speeifie ehemieal eontaminants, the hazards related to the use of speeifie types of equipment) assoeiated with speeifie workplaee aetivities and their related eontrol measures. These general analyses do not provide employees with suflheient information to enable them to work safely, nor do they enable the employer... 

The basic assumption is that the individual always has the choice of whether or not to behave in an unsafe manner. The implication of this assumption is that the responsibility for accident prevention ultimately rests with the individual worker. It also implies that as long as management has expended reasonable efforts to persuade an individual to behave responsibly, has provided training in safe methods of work, and has provided appropriate guarding of hazards or personal protection equipment, then it has discharged its responsibilities for accident prevention. If these remedies fail, the only recourse is disciplinary action and ultimately dismissal.

As a protection for equipment against overload, sprockets are sometimes provided for silent chains with a shearing pin or a break-pin hub. A pin of a known strength is used, and an overload of sufficient magnitude shears the pin and leaves the plate free to turn on the hub. After the overload condition is remedied, a new pin may be easily inserted and the drive again made ready to operate. 

The rig selection will dictate the basic layout of the pad. Based on the necessary area needed to support its functions, ancillary equipment may be added in space conservative measures. In addition to the placement of various stationary rig site components, other operations such as logging, trucking and subsequent completion operations must be provided for. The most environmentally sensitive design will impact the least amount of area, and in that it will be the most economic. Potential pad sites and access routes should be laid out on a topographic map prior to the actual survey. At this time, construction costs can be estimated and compared. Figure 4484 shows such a layout. The cost of building a location includes the cost of reclamation such as any remediation.
