This section of the website is designed to keep you informed about the progress made on the final remediation of the site.  All remediation work is scheduled to be completed by March of 2020. Many action items have been completed or are substantially complete already. To avoid remediation work during the winter, Cherokee has proposed an accelerated timeline from what is provided under the Minster’s Order.

AEP is still reviewing reports that were submitted under the MO and we are revisiting the remediation timeline given AEP’s review is pending.

MINISTER'S ORDERSSTATUS
Develop and implement a temporary dust control planCOMPLETE - A dust control plan has been in place since May 2018 with Alberta Health Services. There have been no dust issues at the property. The plan is primarily for times when there is no activity on the site as it is activity that typically generates dust.
Submit Dust Control ProgramCOMPLETE-ONGOING - In May, the dust control plan was submitted to Alberta Environment and Parks and confirmed by the Ministry in July. The dust control program is phased. During periods of limited site activity, there is a regular monthly inspection of the site conditions to assess vegetation quality and identify areas where dust generation may become an issue if not addressed. During periods of higher site activity, there are daily inspections of the work areas to ensure that the activities are not increasing the potential for dust generation. During remedial activities, where soil disturbance will be required, the dust control program will also include active monitoring of air quality and dust suppression.
Submit the plan to determine the edges of the contamination (Delineation Plan*)SUBMITTED BUT NOT CONFIRMED - Delineation plans were submitted for Parcels X, C and Y on June 10, 2019. The field assessment activities were conducted in July and August. Although submitted, the plans have yet to be confirmed as complete, as they are dependent on the dioxin and furan guidelines which Cherokee is working with Alberta Environment and Parks to establish as soon as possible.
Complete Delineation WorkSUBMITTED BUT NOT CONFIRMED - Drilling and samplings were undertaken in July, 2019 on Parcels X, C and Y. Delineation plans were submitted to Environment and Parks on August 9, 2019. Delineation reports containing the test hole logs, location plans and chemical analysis were submitted to Alberta Environment and Parks in August. Supplemental delineation work was done but has yet to be confirmed as complete, as it is dependent on the dioxin and furan guidelines which Cherokee is working with Alberta Environment and Parks to establish as soon as possible.
Submit Conceptual Site Model (CSM)COMPLETE-ONGOING - The CSM is a living document that shows where the contaminants are located both horizontally and vertically on the property. The CSM was initially provided on May 15, 2019 and was updated with additional data on September 6, 2019. The requirement to provide the CSM within 180 days has been satisfied. Any further updates will be provided as new data becomes available.
Submit Human Health Risk Assessment (HHRA)COMPLETE & UNDER REVIEW - One of the main purposes of the HHRA is to set the criteria for dioxins and furans. In March, a HHRA was submitted to Alberta Environment and Parks. Cherokee and Alberta Environment and Parks have had ongoing discussions on the HHRA. Cherokee provided two further submissions of supplemental information. The information is with Alberta Environment and Parks for review.
Submit Site Specific Risk Assessment (SSRA) COMPLETE & UNDER REVIEW - A SSRA for human and ecological considerations was submitted on May 27, 2019. Cherokee is awaiting comments from Alberta Environment and Parks.
Submit Risk Management & Remediation PlanINCOMPLETE AWAITING GUIDELINES FOR DIOXINS & FURANS - The Remediation Plan for Parcel Y was submitted in March, 2019 and a revised version was submitted on September 21, 2019. The Remediation Plans and Risk Management Plan are contingent on the establishment of guidelines for dioxins and furans, which Cherokee is working with Alberta Environment and Parks to establish as soon as possible. The deadline for these submissions is now December 6, 2019.
Submit Long Term Monitoring PlanINCOMPLETE AWAITING GUIDELINES FOR DIOXINS & FURANS - Long Term Monitoring Plans for the parts of the site that will remain under risk management (the berm and Parcel X) are dependent on dioxin and furan guidelines, which Cherokee is working with Alberta Environment and Parks to establish as soon as possible. The deadline for these submission is now December 6, 2019.
Complete Remediation workINCOMPLETE AWAITING GUIDELINES FOR DIOXINS & FURANS - Cherokee had hoped to have completed full remediation by the end of November, 2019, however this work is dependent on the confirmation of guidelines for furans and dioxins which have not been established. Cherokee continues to work with Alberta Environment and Parks to establish these guidelines as soon as possible.
ENVIRONMENTAL PROTECTION ORDER 
Submit Delineation Plans for Verte HomesteaderSUBMITTED BUT NOT CONFIRMED - The delineation plan for Verte Homesteader (Parcel C) was submitted to Alberta Environment and Parks on June 10, 2019. Confirmation of this plan depends on the guidelines for dioxins and furans, which have not yet been determined. Cherokee continues to work with Alberta Environment and Parks to establish these guidelines as soon as possible.
Complete Delineation for Verte HomesteaderCOMPLETE AWAITING GUIDELINES FOR DIOXINS & FURANS - The delineation work for Verte Homesteader (Parcel C) was completed in July and submitted to Alberta Environment and Parks in August, 2019. The work has not been confirmed as complete as it is dependent on the guidelines for dioxins and furans, which have not yet been determined. Cherokee continues to work with Alberta Environment and Parks to establish these guidelines as soon as possible.
Submit Remediation Plans for Verte HomesteaderSUBMITTED BUT NOT CONFIRMED - The remediation plan for Verte Homesteader was submitted on April 18, 2019, and remediation of a small area in the northeast corner of the parkette was carried out in August 2019. Confirmation of the plan and completion of the remediation depends on e guidelines for dioxins and furans, which have not been determined. Cherokee continues to work with Alberta Environment and Parks to establish these guidelines as soon as possible.
Complete Remediation for Verte HomesteaderSUBMITTED BUT NOT CONFIRMED - A small area of soil in the northeast corner of the parkette was excavated and backfilled. Soil samples were submitted and analysed at a laboratory. The remediation work has not been confirmed as complete as it is dependent on the guidelines for dioxins and furans, which have not been determined. Cherokee continues to work with Alberta Environment and Parks to establish these guidelines as soon as possible.

* Delineation – find the edges of contamination which exceed Tier 1 or 2 guidelines.
