No general allowance was made for site restoration, since this cost is highly variable. The cost of purchasing, installing, and commissioning a 250-ton/day mobile ChemTech soil treatment plant is estimated to be approximately 1.5 million (U.S. dollars, 1997). 

The estimated total cost to treat 125,000 m of soil from the Sviluppo Linate in Milan, Italy, at a rate of 25 tons per hour was 22 million. This estimate excludes excavation, debris removal, treatment and disposal of residual solids and effluents, site restoration, utilities, and the cost of bench- and pilot-scale testing (D158898, p. 333, 342). The vendor estimated that it would cost 150 to 200 per ton to treat 500,000 tons of soil using the B.E.8.T. Model 615 unit at a rate of 200 to 300 tpd. This estimate includes mobilization and demobilization costs but excludes the costs of site excavation, civil work, taxes, prescreening needs, site management, and effluent disposal (D199319, p. 6).

Intertidal fauna include animals that live in the shoreline zone between the high and low tides. These organisms are the most vulnerable to oil spills because they and their habitat are frequently coated during oil spills. Typical fauna include the mobile crabs, snails, and shrimp, sessile (immobile) barnacles and mussels, and sedentary limpets, periwinkles, and tube worms. Heavy oiling will generally kill most species. The area does recolonize after the spill with the mobile species returning first, but recovery takes months and sometimes years. Recolonization by plants and sessile species is the major factor in site restoration. 

Site restoration arises from damage assessment. Sites are restored by replanting trees and vegetation and recolonizing animals and birds at a site. While this appears simple and beneficial, it is fraught with difficulties and can upset the ecological balance in some areas if not carried out carefully. It is difficult and sometimes impossible to recolonize or move certain species of animals. Furthermore, a damaged site will often require a succession of different plant and animal species in recovery before a balance is achieved. If not carefully planned and conducted, human intervention can upset this natural succession process. 

Prosecutions fines the internet CER refers to a Can 35000 fine for a discharge of methanol into the ocean in 1996. No mention is made in the published CER of the absence or occurrence of any fines and prosecutions. At the end of 1999 Methanex had accrued US 46 million for obligations relating to the future removal and site restoration costs. 

The Army Corps of Engineers provides technical support for site investigations, recoveries, and site restorations to Army and DOD organizations and is responsible for cleaning up formerly used defense sites. Restoration activities concerning the handling and disposal of nonstockpile chemical warfare material are coordinated with and authorized by the Army Chemical Demilitarization and Remediation Activity. 

Hazard Area Restoration - Removal of the radiological hazard is not a military mission unless the Commander has a clear need for the facility out of military necessity. Commanders shall involve Civil-Military affairs officers once the extent of the radiological hazard is realized to ensure coordination is conducted with the civilian authorities for site restoration. 

After the incident has been declared under control and acute emergency conditions no longer exist, post-incident activity and stabilization should commence. Activity during this period may include cleanup and disposal, accident investigation/incident reconstruction, site restoration, and emergency plan evaluation. 

The superoxide substrate is supposed to bind the oxidized metal, increasing its coordination number to six. On releasing the product O2, the bound hydroxyl is protonated, forming a coordinated water molecule. A second superoxide molecule then approaches the catalytic center and binds to the reduced metal. The superoxide is reduced by the metal and protonated by the water, forming the second product, hydroperoxide, which finally leaves the active site, restoring the original catalytic center.

The upper, open-ended band represents low-probability severe reactor accidents with consequences beyond the facility boundary. It is not expected that any off-site evacuation of the public would be needed under any circumstances for small power reactors, however, minor releases of radioactivity within the specified regulatory limits may occur. The accident response team would secure the site, restore a safe, contained shutdown state, and perform any required cleanup. 

Figure 44. Illustration of the calculated structure of a layer of H2O soibed onto the Fe-Os-Fe termination of hematite (001) viewed perpendicular (a) and parallel (b) to [001], from Becker et al. (1996). In this calculation, three H2O molecules coordinate each uppermost surface Fe site, restoring the 6-fold coordination at these sites. The H2O layer is stabihzed by intersorbate and sorbate-Os layer hydrogen bonds.

The Poiiution Prevention and Control Act 1999 will, by 2007, replace the Integrated Pollution Control Regulations made under Part 1 of the EPA by extending those powers to cover waste minimization, energy efficiency, noise and site restoration. 

With increasing size of individual quarries, the problems associated with site restoration have correspondingly increased. 

An alternative useful quarry site restoration method is to utilize the excavations for refuse disposal, so that they are filled in before final landscaping. 

Planning the site restoration measures involves hillsides, benches, final quarry floor, tips and settling ponds. In addition, the effect of trees and shrubs planted in connection with these measures upon the propagation of noise, waste gases and noise should be taken into consideration.
