That is not to say that the RCRA program would lack the authority to go back to a RCRA facility that had been addressed under CERCLA and request additional work. However, as a matter of program policy, once a facility is referred to CERCLA, we would not actively monitor the progress of the facility and would not expect the facility to "return" to RCRA, barring some unforeseen event. This event should not be used for facilities that are only receiving an initial assessment from the Superfund program, and are expected to return to the RCRA program for the facility investigation and facility remediation steps. However, if a RCRA facility, such as one that has converted to less than 90-day storage, has, as a matter of national policy, been deferred to the Superfund program and if, in the case specific circumstance, the Region or authorized state has clearly transferred this facility to the Superfund queue, then the "Referred to a Non-RCRA Authority" event could be entered for this facility.

CA225	Stabilization Measures Evaluation	This event indicates that the feasibility and appropriateness of stabilization activities at this facility have been evaluated. Status Codes (required) IN - The facility is not amenable to stabilization activity because of a lack of technical data. An evaluation has been completed, but further data is necessary to determine stabilization measures, feasibility or appropriateness. NF - The facility is not amenable to stabilization activity at the present time, because it appears to be technically infeasible or inappropriate. NR - The facility is not amenable to stabilization activity at the present time for reasons other than 1) it appears to be technically infeasible or inappropriate (NF); or 2) there is a lack of technical information (IN). Reasons for this conclusion may be the status of closure at the facility, the degree of risk, timing considerations, the status of corrective action work at the facility, or other administrative considerations.

Status Codes (required) NR - No Remedy Constructed. Applies on the actual date of the CA400 - Remedy Decision if no physical construction of a remedy has been needed since site characterization activities began. OF - Operating Facility / Remedy Deferred. Applies to each operating area at the facility that has been deferred. It applies on the actual date the agency approves the facility's demonstration that the above criteria have been met for the deferred operating area(s). This status code also applies to the entire facility when all non-operating areas and all non-deferred operating areas have a CA550NR or CA550RC event code, AND all deferred operating areas have a CA550OF code. When applied to the entire facility, the actual date of the CA550OF event code should be the later of the last CA550NR/RC or CA550OF event code which is linked to an individual area or group of areas. RC -Remedy Construction. Applies after the actual date of the CA400 - Remedy Decision when either: 1) all necessary physical construction of the last corrective measure has been completed and all remedial systems are fully functional as designed, whether or not final cleanup levels or other requirements have been achieved, or 2) if all necessary physical construction of all remedial systems is fully functional as designed as a result of stabilization measures implemented prior to the actual date of the CA400 - Remedy Decision whether or not final cleanup levels or other requirements have been achieved.	Initiating Source - A Remedy Decision and Response to Comments or other appropriate decision document indicating that no further physical construction of a remedy is needed Nationally Required - Yes Schedule Date -(NR) Scheduled date for the remedy decision if no further physical construction of a remedy is expected to be needed; (OF) Date the State or EPA is expected to acknowledge, in writing, that the criteria for remedy deferral in operating areas at the facility have been satisfied; (RC) Date the State or EPA is expected to acknowledge, in writing, that any necessary physical construction of the last corrective measure is complete and all remedial systems are fully functional as designed, whether or not final cleanup levels or other requirements have been achieved Actual Date - (NR) Date for the remedy decision if no further physical construction of a remedy is needed; (OF) Date the State or EPA approves, in writing, that the criteria for remedy deferral in operating areas at the facility have been satisfied; (RC) Date the State or EPA acknowledges, in writing, that any necessary physical construction of the last corrective measure is complete and all remedial systems are fully functional as designed, whether or not final cleanup levels or other requirements have been achieved Guidance - 1) The Remedy Construction measure is an important milestone of Corrective Action progress designed to measure the progress of remedy implementation. The measure Remedy Completion with or without Controls (CA900) is intended to be used to indicate the true status of completion at RCRA Corrective Action facilities. 2) Stabilization measures implemented prior to the Remedy Decision should be recorded under CA600 and CA650. 3) Remedy deferrals must have a substantive technical basis and should only be used in very limited circumstances such as where implementation of the final remedy would cause undue interruption o f a critical process or destruction of an integral portion of the subject operating area(s). 4) The Responsible Agency should also enter a CA555 event code with either a projected date or actual date to be linked to the same area(s) upon entry of a CA550OF event code; 5) Tracking of SWMU CA at the individual area level is encouraged, but not required, to implement the CA550OF code. Though it is necessary to individually identify and track deferred CA550OF areas from non-deferred and non-operating areas, implementers may continue to group areas consistent with agency data management policies and procedures. Note: A CA550 event cannot be entered unless a CA400 event exists that is linked to the same area(s) as the CA550 event.
CA555	Remedy Construction Deferral Expiration	The event to document the expiration date of the deferral of final remedy construction in specified operating areas at the facility. The CA550OF deferral is only for a specified period of time and shall not extend beyond the active life of the critical process or integral component in the deferred operating area(s) that is the basis for the deferral.	The projected end date of the remedy deferral for a specific area should be based on the reasonably anticipated duration of the conditions necessitating the deferral, but shall not extend beyond the reasonably anticipated active life of the critical process or integral component in the operating area(s) that is the basis for the deferral. The projected end date of the remedy deferral for an entire facility area should be set as the latest projected end date of the individual areas to which a CA550OF event code is linked. In the event that the critical process or integral component is discontinued, any necessary supplemental investigation must be completed and the final remedy constructed/implemented. If the critical process or integral component is shut-down for major repairs or renovations, or is replaced by another component, any necessary supplemental investigation should be completed and the final remedy constructed/implemented during the shut-down or changeover to the replacement process/component, if practicable. Initiating Source - 1) The State or EPA approval, in writing, that the criteria for remedy deferral in an operating area(s) at the facility has been approved for a specified period of time; 2) The State or EPA decision document terminating a remedy deferral at the facility, e.g. a permit mod or enforcement action; 3) Correspondence from the facility documenting that the criteria for remedy deferral no longer apply, e.g., the process or integral component is no longer operating, or the criteria for the remedy deferral as specified for the CA550OF status code are no longer satisfied Nationally Required - Yes Schedule Date - Date the remedy deferral in an operating area(s) at the facility is expected to be terminated Actual Date - Date the remedy deferral in an operating area(s) at the facility has been terminated Guidance - When construction of the final remedy has been deferred at the facility level (e.g. CA550OF is linked to the 'Entire Facility' area), this event should also be linked to the 'Entire Facility' area. When construction of the final remedy has been deferred for only specific portions of the RCRA facility, this event should be linked to the specific areas affected by the control or controls. If there are more than one remedy deferrals for a facility which may have different expiration dates (e.g., multiple operating process areas which may cease operating at different times), then a separate CA555 event code should be entered for each such area.
CA600	Stabilization/Interim Measures Decision	EPA's or the State's notification or written acknowledgement to the RCRA facility that a stabilization activity or activities are required or otherwise being undertaken. The notification mechanism could be an enforcement order, order modification, permit, or permit modification or similar enforceable state authority requiring the facility to undertake stabilization activity; it may also take the form of a written acknowledgement from EPA or the State that stabilization activity is being undertaken. The notification or acknowledgement must contain written stabilization objectives, goals, performance standards, or desired results. The stabilization activity must control or abate threats to human health and/or the environment from releases, and/or prevent or minimize the further spread of contamination. Facility initiated stabilizations/interim measures shall also be tracked with this event code. Status Codes (not required) EC - Primary measure is exposure control by barrier and/or institutional control (e.g., capping, fencing, deed restrictions) GW - Primary measure is groundwater extraction and treatment (e.g., to achieve groundwater containment, to achieve MCL) OT - Primary measure is other activity SR - Primary measure is source removal and/or treatment (e.g., soil or waste excavation, in-situ soil treatment, off-site treatment)	Initiating Source - Enforcement order, order modification, permit, permit modification, similar enforceable state authority requiring the facility to undertake stabilization activity, or written acknowledgement from the State or EPA that stabilization activity is being undertaken Nationally Required - No Schedule Date - Date the State or EPA is expected to sign the final order, order modification, permit, permit modification, or written acknowledgement Actual Date - Date the State or EPA signs the final order, order modification, permit, permit modification, or written acknowledgement
CA650	Stabilization Construction Completed	The event by which the State or EPA formally notifies the RCRA facility that the interim measures undertaken have been completed to the satisfaction of the Agency; and/or the event by which the State or EPA formally notifies the RCRA facility that stabilization objectives have been met, but require continued operation and maintenance to maintain this level of performance. Status Codes (not required) EC - Primary measure is exposure control by barrier and/or institutional control (e.g., capping, fencing, deed restrictions) GW - Primary measure is groundwater extraction and treatment (e.g., to achieve groundwater containment, to achieve MCL) OT - Primary measure is other activity SR - Primary measure is source removal and/or treatment (e.g., soil or waste excavation, in-situ soil treatment, off-site treatment)	The status codes for this event provide information on the types of stabilization actions that are being implemented. This information is routinely requested in Congressional inquiries and will be helpful to Headquarters in characterizing national implementation efforts. Initiating Source - Letter from the EPA or the State to the facility or an internal written memorandum acknowledging stabilization completion and/or construction completion - conducted through a final order, order modification, permit, permit modification, or written acknowledgement that the activity has occurred from EPA or the State Nationally Required - No Schedule Date - Date the activity is expected to be completed Actual Date - Date the activity is completed Guidance - It was recommended that the corrective action program take credit nationally for stabilization efforts that are clearly completed, such as excavations, but also for those efforts that are performing to meet the Agency's stabilization objectives, yet require continued operation and maintenance to maintain this level of performance. The definition for CA650 incorporates these concepts. The definition allows "credit" once EPA or the State provides a written determination that the stabilization activity at a facility is completed in a manner that meets the stabilization objectives, goals, performance standards, or desired results. For example, an excavation is completed once the contaminated material has been removed in accordance with the objective of the stabilization measure. An additional example is a groundwater stabilization measure in which a pump and treat system has been constructed and is operating in a manner which achieves the stabilization objective even though continued operation and maintenance is necessary to maintain this level of performance.
CA725	Current Human Exposures Under Control Determination	The event by which the State or EPA completes and Environmental Indicators (EI) Evaluation verifying that the current human exposures are under control in accordance with guidance from EPA Headquarters. EI evaluations are performed on a facility-wide basis. Therefore, this event should only be linked to the entire facility and not to specific areas. Status Codes (required) IN - More information is needed to make a determination NO - Current human exposures are NOT under control YE - Current human exposures under control has been verified. Based on a review of information contained in the EI determination, current human exposures are expected to be under control at the facility under current and reasonably expected conditions. This determination will be reevaluated when the Agency/State becomes aware of significant changes at the facility.	Initiating Source - Documentation of Environmental Indicator Determination form signed by preparer and his/her supervisor. Signed hard copies of the form should reside in the administrative file for the facility. These forms should also be kept in electronic format that can be posted on an "EI database" web site developed by the Office of Solid Waste. Click here for guidance on how to determine if a facility has met RCRA corrective action environmental indicators. Nationally Required - Yes Schedule Date - Date this event is anticipated Actual Date - Date that the EPA or State documents that the facility has achieved the event, or that the event determination is no longer applicable Guidance - Effective 2/5/1999 per revised program guidance: Status codes NC and NA should no longer be used. Previously entered NC or NA status codes should be updated, but may remain in the database until they are replaced by more recent codes. Implementers should consult the most recent EI guidance for performing an EI evaluation prior to entering this event code.

CA750	Groundwater Releases Controlled Determination	The event by which the State or EPA completes an Environmental Indicators (EI) Evaluation verifying that the migration of contaminated groundwater is under control in accordance with guidance from EPA Headquarters. EI evaluations are performed on a facility-wide basis. Therefore, this event should only be linked to the entire facility and not to specific areas. Status Codes (required) IN - More information is needed to make a determination NO - Unacceptable migration of contaminated groundwater is observed or expected YE - Migration of contaminated groundwater under control has been verified. Based on a review of information contained in the EI determination, it has been determined that migration of contaminated groundwater is under control at the facility. Specifically, this determination indicates that the migration of contaminated groundwater is under control, and that monitoring will be conducted to confirm that contaminated groundwater remains within the existing area of contaminated groundwater. This determination will be re-evaluated when the Agency becomes aware of significant changes at the facility.	Initiating Source - Documentation of Environmental Indicator Determination form signed by preparer and his/her supervisor. Signed hard copies of the forms should reside in the administrative file for the facility. These forms should also be kept in electronic format that can be posted on an "EI database" web site developed by the Office of Solid Waste.

Previously entered NA an NR status codes should be updated, but may remain in the database until they are replaced by more recent codes. Implementers should consult the most recent EI guidance for performing an EI evaluation prior to entering this event code. Click here for guidance on how to determine if a facility has met RCRA corrective action environmental indicators.
CA770	Engineering Controls Established	This event signifies the establishment of engineering controls (ECs) as part of, or to augment, an interim or final corrective action. ECs consist of engineering measures (e.g, caps, treatment systems, etc.) designed to minimize the potential for human exposure to contamination by either limiting direct contact with contaminated areas or controlling migration of contaminants through environmental media. This event should also be entered when ECs are established for regulated units undergoing closure and/or post-closure care, including engineering controls required under 40 CFR 264 and 265. Status Codes (required) GW - Groundwater control which includes any EC pertaining to groundwater, including in situ and ex situ treatment like bioremediation, in situ permeable reactor barriers, monitored natural attenuation (MNA), longterm monitoring, etc. NG - Non-groundwater controls referring to any control not related to groundwater, such as barriers or caps.

Guidance - When ECs are established at the facility level (e.g., site security), this event should be linked to the "entire facility" area. When ECs are established and affect only portions of the RCRA facility, this event should be linked to the specific area affected by the control. For further guidance with respect to ECs, refer to the latest One Cleanup Program guidance (OSWER 9355.0- 74FS-P). This document can be found at http://www.epa.gov/superfund/resources/institut/guide.pdf
CA772	Institutional Controls Established	This event signifies the establishment of institutional controls (ICs) as part of, or to augment, an interim or final corrective action. ICs are defined as non-engineered and/or legal controls that minimize the potential for human exposure to contamination by limiting land or resource use. This event should also be entered when ICs are established for regulated units undergoing closure and/or post-closure care, including notices to deed and survey plats required under Sub-part G of 40 CFR 264. Status Codes (required) EP - Enforcement and permit tools which includes permits, orders, or other enforceable agreements.

CA780	Engineering Controls Terminated	This event significies that the engineering control is no longer required to protect human health and the environment. Use this code where a CA770 [Engineering Controls (ECs) Established] was entered and the control(s) subsequently terminated. Status Codes (required) GW - The control is related to groundwater such as situ and ex situ treatment like bioremediation, in situ permeable reactor barriers, monitored natural attenuation (MNA), long term monitoring, etc. NG - The control is not related to groundwater such as barriers or caps.	Initiating Source - Enter this code upon completion of required activities and approval by the State / EPA of the decision document required to terminate controls at the facility. This decision document would be the mechanism put in place by the State / EPA to terminate the controls, e.g. a permit mod Nationally Required - Yes Scheduled Date - Date EC is scheduled to be terminated Actual Date - Date EC is terminated Notes - Indicate location where additional information concerning the specific control can be accessed (e.g. responsible agency contact information, web site address, etc.). Indicate any specifics about the control termination Guidance - When ECs were established at the facility level (e.g. site security), this event should be linked to the 'entire facility' Area. When ECs were established and affect only portions of the RCRA facility, this event should be linked to the specific areas affected by the control or controls. If both groundwater and non-groundwater controls exist for a particular area, enter an event code for each control. For further guidance with respect to ICs and/or ECs refer to the latest One Cleanup Program guide (OSWER 9355.0-74FS-P). This document can be found at http://www.epa.gov/superfund/resources/institut/guide.pdf
CA782	Institutional Controls Terminated	This event signifies that the institutional control is no longer required to protect human health and the environment. Use this code where a CA772 [Institutional Controls (ICs) Established] was entered and the control(s) subsequently terminated. Status Codes (required) EP - Includes permits, orders, or other enforceable agreements. GC - Implemented and enforced by State or local governments; excludes permits, orders and other enforceable agreements. ID -Includes information or notification of contamination present at property. PR - Relies on legal instruments placed in the chain of title for the property	Initiating Source - Enter this code upon completion of required activities and approval by the State / EPA of the decision document required to terminate controls at the facility. This decision document would be the mechanism put in place by the State / EPA to terminate the controls, e.g. a permit mod Nationally Required - Yes Scheduled Date - Date IC is scheduled to be terminated Actual Date - Date IC is terminated Notes - Indicate location where additional information concerning the specific control can be accessed (e.g. responsible agency contact information, web site address, etc.). Indicate any specifics about the control termination Guidance - When ICs are established at the facility level (e.g. site security), this event should be linked to the 'entire facility' Area. When ICs are established and affect only portions of the RCRA facility, this event should be linked to the specific areas affected by the control or controls. If more than one control exists for a particular area, enter an event code for each control. For further guidance with respect to ICs and/or ECs refer to the latest One Cleanup Program guide (OSWER 9355.0-74FS-P). This document can be found at http://www.epa.gov/superfund/resources/institut/guide.pdf
CA800	Ready for Anticipated Use	The event by which the State or EPA makes an RAU determination and completes an RAU form. The form notes that the RCRA facility, or designated portion of the facility, has met all of the following Ready for Anticipated Use Criteria outlined in the Cross-Program Revitalization Measures (CPRM) Guidance: The facility or facility area has met the Human Exposures Environmental Indicator (CA725YE), and the event has been entered into RCRAInfo; Cleanup goals have been achieved for media that may affect current and reasonably anticipated future land uses of the facility so that there are no unacceptable risks; and All institutional or other controls, identified as part of a response action or remedy as required to help ensure long-term protection, are in place. The RAU milestone is achieved when a piece of property can be safely used for an anticipated use and, depending upon the anticipated future use, may not require a facility-wide construction complete determination. For example, the surface of a property may be safely used at some facilities while groundwater contamination is still being addressed. More information on the Ready for Anticipated Use measure is presented in the "Guidance for Documenting and Reporting RCRA Subtitle C Corrective Action Land Revitalization Indicators and Performance Measures, Status Codes (required) NO - The facility or area is not Ready for Anticipated Use. This status code applies if, for any reason, a previous RAU determination is no longer true (i.e. the anticipated use of a site could change or a human exposures determination could change). YE - The facility or area is Ready for Anticipated Use.	Initiating Source - State or EPA RAU form completed, signed, and submitted to the file. The form indicates that each of the RAU criteria have been met, and whether the RAU determination is for specific areas or the entire facility. Nationally Required - Yes Actual Date - The date the State or EPA completes and signs the RAU form acknowledging, in writing, that the facility or facility area, has met the RAU criteria Guidance - The Ready for Anticipated Use measure is an important aspect of a RCRA Corrective Action cleanup as it communicates that a facility or facility area is safe and ready for its next anticipated use. RCRA Corrective Action facilities that have achieved a CA999-Corrective Action Process Terminated determination have probably met the RAU criteria. Before an RAU determination is made for these facilities, however, the facility and/or the overseeing agency must verify that institutional controls are either unnecessary or are in place and effective. Prior to making an RAU determination, the event code for achieving the human exposures environmental indicator (CA725YE) must be entered in RCRAInfo. RAUs for the entire facility must be linked to the "Entire Facility" area. Phased or partial RAUs are to be attached to specific areas of implementation and not to the "Entire Facility" area.
CA900	CA Performance Standards Attained	This event indicates remedies selected for the protection of human health and the environment standard have been fully implemented and associated performance standards have been attained at the entire facility or specific areas within the facility. Status Codes (required) CR - Controls are required. NC - No controls are necessary.	Initiating Source - Written acknowledgment, processed through proper procedures, that corrective action performance standards have been achieved Nationally Required - Yes Scheduled Date - Date that the State or EPA expects to issue its written acknowledgment that corrective action performance standards have been achieved Actual Date - Date that the State or EPA issued its written acknowledgment that corrective action performance standards have been achieved
CA999	Corrective Action Process Terminated	This event indicates the completion of the corrective action process for the entire facility or for areas at the facility; that active remedial measures as specified in the RCRA permit or enforcement order are completed, and that all obligations with respect to compliance with 40 CFR Part 264.101 or equivalent State requirements with respect to known Solid Waste Management Units (SWMUs) or Areas or Concern have been met. Status Codes (not required) NF - Site characterization has demonstrated the attainment of the final RCRA Corrective Action goals without any active remediation. RM - Active remediation or stabilization has been implemented and the facility has demonstrated the attainment of the final RCRA Corrective Action goals.	Initiating Source - Written acknowledgement, places in the facility file, stating that all projected activity has been completed Nationally Required - Yes Schedule Date - Date the event is scheduled to be completed Actual Date - Date the sequence of events was completed Guidance - This event should be entered 1) after the Certification of Remedy Completion or Construction Completion (CA550-CMI Completed), and/or 2) after a stabilization measure(s) has been completed in a manner that meets the stabilization objectives, goals, performance standards, and/or desired results (CA650), and terminating corrective action at this point at the facility or area would satisfy all permit or order requirements for CA.
