["Monitored Natural Recovery","Concentrations of COCs in sediment and tissue are decreasing at a rate to meet RAOs within an acceptable time frame."]
[null,"Low concentrations (relative to cleanup goals) are present over large areas at the site."]
[null,"Net sediment deposition rates are adequate to consider natural sedimentation as a reasonable alternative to meet RAOs."]
[null,"There is evidence that contaminants are degrading to less toxic constituents, the COCs are known to degrade, or natural sequestration is making contaminants less biologically available."]
[null,"Dispersion of contaminants is occurring quickly enough to meet RAOs in an acceptable time frame, and is consistent with RAOs (e.g., if RAOs allow for off site migration of contaminants)."]
[null,"Based on these conditions, should MNR be retained for further consideration?(YES/NO)?"]
["Enhanced Monitored Natural Recovery","Enhancing one or more MNR processes (e.g., accelerate the sedimentation rate by application of a thin layer cap to reduce the concentration of the COC in the bioavailable layer) is expected to cause RAOs to be reached within a reasonable time frame."]
[null,"Enhancing one or more MNR processes is compatible with current and future land and waterway use."]
[null,"Characteristics of the site do not inhibit  or prevent placement of enhancement materials."]
[null,"Sediment conditions are stable enough for the emplaced material to remain in place and be effective."]
[null,"Based on these conditions, should enhanced MNR be retained for further consideration? (YES/NO)?"]
["In-Situ Treatment","COCs are amenable to treatment, and treatment can be achieved in a time frame consistent with the RAOs ."]
[null,"Conditions are such that the amount of in situ treatment amendments needed is considered practical, stable, and is consistent with the RAOs."]
[null,"Conditions are such that in situ treatment amendments can be delivered effectively (e.g., debris or other factors do not prevent mixing)."]

[null,"Based on these conditions, can in-situ treatment be retained for further consideration? (YES/NO)?"]
["Conventional Capping","Will the cap effectively isolate the COCs for an adequate time frame (with monitoring and maintenance)."]
[null,"Is capping compatible with current and future land and waterway use?  (Physical conditions (e.g., debris, slope stability, load bearing capacity) are such that they allow establishing an effective cap.)"]
[null,"Based on these conditions, can conventional capping be retained for further consideration? (YES/NO)?"]
["Amended Capping","Amended cap will effectively treat COCs (e.g., isolate or reduce the bioavailability), is compatible with future site use expressed in the RAOs, and is expected to function for an adequate time frame (with monitoring and maintenance)."]
[null,"Is amended capping compatible with current and future land and waterway use.  "]
[null,"Physical conditions (e.g., debris, slope, load bearing capacity) are such that they allow establishing an effective cap."]
[null,"Based on these conditions, can amended capping be retained for further consideration? (YES/NO)?"]
["Excavation (dry)","Site conditions (e.g., water level fluctuation, water depth, ability to install hydraulic barrier and/or sheet piles, waterway configuration, etc.) are amenable to dry excavation ."]
[null,"The contaminant distribution is limited in extent so that its isolation by the installation of the hydraulic barrier(e.g. earthen berm, sheet piles, coffer dams, stream re-routing etc.) is practical."]
[null,"Removal is practical (for instance, the site does not have extensive, structures or utilities)."]
[null,"Dredged material disposal sites and/or processing/treatment facilities are available."]
[null,"Based on these conditions, can excavation be retained for further consideration? (YES/NO)?"]
["Dredging (wet)","Sediments are shallow enough to implement environmental dredging with existing technology (e.g., less than 100 ft water depth)."]
[null,"Dredging is practical (i.e., the site does not have extensive debris, structures, hard bottom, or utilities)."]
[null,"Water quality impacts of dredging are expected to be acceptable."]
[null,"There are areas present for staging, handling, dewatering, disposal, and processing/treatment of the dredged material."]
