This page contains copies of correspondence, documents and reports related to a property in Shawnigan Lake that previously operated as a contaminated soil landfill and is now undergoing final closure. To keep the community informed on the status of the site, this page is updated regularly with most of the new content being posted under the Spill Prevention Order Information MO1701 section.
Site history
The property at 460 Stebbings Road in Shawnigan Lake was previously authorized under the Environmental Management Act (EMA) as a contaminated soil remediation facility and landfill. A permit was originally issued to Cobble Hill Holdings Ltd. (CHH) in August 2013, allowing the company to treat contaminated soil, landfill soil that cannot be treated, and discharge treated effluent to an ephemeral stream. An information sheet about the permit (PDF) contains further details. The permit was specific to contaminated soil management activities on the property. Other quarrying activities occurring on Lot 23 and the adjacent Lot 21 are regulated by the Ministry of Energy, Mines and Petroleum Resources under the Mines Act.
On January 27, 2017, the permit was suspended because the permittee did not address outstanding non-compliances in a timely manner and a Spill Prevention Order (SPO) was issued. On February 23 the permit was cancelled, and on March 15 the SPO was amended to specify additional actions to be taken to ensure ongoing protection of the environment and human health.
The current regulatory instrument in place at the site is the SPO (second amended version dated June 29, 2017). As required in the SPO, the company submitted a plan to permanently close the landfill in accordance with provincial standards for landfill closure. Minor construction activities were approved and completed in the fall of 2017 to ensure the existing landfill cell was secured while the totality of the Final Closure Plan was undergoing review.
On June 26, 2019, after a comprehensive review of the Final Closure Plan by ministry staff and independent qualified professionals, CHH received approval to proceed with final closure activities which they propose to implement in 2019. The Minister of Environment and Climate Change Strategy has approved the 2019 Final Closure Plan for the Cobble Hill Holdings landfill with conditions. Based on a comprehensive technical review of the plan and taking into consideration the scientific evidence and data, the approved plan with conditions provides for sufficient protection of the environment and watershed. Input from community representatives and the named parties was also reviewed and considered. For more information, please see the Reasons for Decision document.
Copies of documents related to the permit are posted below under Permit Information and copies of documents related to the SPO are posted below under Spill Prevention Order Information MO1701.
Please refer to the Frequently Asked Questions section for responses to inquires we have received.
Spill Prevention Order information MO1701
The Spill Prevention Order (SPO) requires Cobble Hill Holdings Ltd. and other Named Parties to prevent the discharge of leachate and waste to the environment. The original Order was issued at the time the permit was suspended, and it included requirements to keep the soil covered, to collect all leachate and to only dispose of it at an authorized off-site facility, and to report to the ministry on an ongoing basis about the leachate being collected and managed.
On March 15, 2017, after the permit was cancelled, the SPO was amended to require the Named Parties to either permanently close the landfill or remove the soil. It was further amended on June 29, 2017, to acknowledge that the Named Parties have elected to permanently close the landfill, and more requirements related to the Final Closure Plan and implementation schedule were added.
On August 11, 2017, the Minister of Environment and Climate Change Strategy approved minor construction works to lessen the risk of an escape or spill of contaminants to the environment during the fall and winter. Requirements for additional assessments, monitoring and reporting were added at that time, to inform a final decision on the Plan. On June 26, 2019, after a comprehensive technical review of the plan by ministry staff and independent qualified professionals, and taking into consideration the scientific evidence and data, the minister approved the Plan with conditions.
The Minister of Environment and Climate Change Strategy has approved the request from Cobble Hill Holdings for an alternative date to complete construction activities for implementation of the Updated Final Closure Plan.
Closure of the landfill was completed in the fall of 2020. The SPO was further amended on February 17, 2021 to reflect the site’s post-closure status.

Permit information
Permit 105809 was issued to Cobble Hill Holdings Ltd. (CHH) on August 21, 2013.
During the permitting process, the ministry received approximately 300 submissions from the local government, First Nations, health officials and members of the general community in response to a draft permit issued in March 2013. Technical staff in the ministry reviewed and responded to these submissions, and based on input received, the draft permit was adjusted to include a number of additional measures addressing health and environmental concerns. The final decision was based on the technical merits of the proposal. The statutory decision-maker looked at the proposed project, including associated environmental concerns, and concluded that the proposal adheres to legislation and appropriately manages environmental risks and human health concerns.
The permit was appealed after it was issued, but in March 2015 the Environmental Appeal Board (EAB) upheld the permit decision See EAB Decision (PDF). The permit was amended by the Statutory Decision Maker (SDM) on June 4, 2015, to incorporate requirements as directed by the EAB. In response to new information obtained in the first year of operation, additional requirements were set by the SDM in June 2016. A copy of the permit and associated amendments, along with some of the technical reports which supported the issuance of the permit, are posted below under 'Permit Information'.
The permit was suspended by the Minister of Environment on January 27, 2017, and was cancelled on February 23, 2017.
Permit compliance
In order to exercise the rights granted by permits issued under EMA, the ministry expects full compliance with all requirements at all times; non-compliance with permit conditions compromises the ability of the permit as a whole to protect the environment. Ministry staff have been monitoring the site for compliance on an ongoing basis in accordance with ministry policies and procedures (PDF). Copies of compliance records and associated correspondence are posted below. The ministry will continue to share information and liaise as necessary with agency partners including Island Health and the Cowichan Valley Regional District with respect to the permit and the site.

Pollution Prevention Order 108608
The Ministry of Environment determined that CHH did not manage water on the site according to their permit during an October 8, 2016 rain event. With a forecast of additional heavy rainfall, the ministry staff took action to ensure the protection of human health and the environment. A Pollution Prevention Order (PDF) was issued requiring CHH to immediately undertake measures to prevent issues with the water management system on site.
The Pollution Prevention Order was cancelled on March 17, 2017, because the requirements were duplicative with those included in the Spill Prevention Order issued by the Minister on March 15, 2017.

- The permittee continues to report to the ministry that the actions required by the Order are being complied with and documentation is being provided in support of this.
- Photo of the site as of Nov 17, 2016, is attached here.
- Copies of data from water quality analyses conducted by the permittee are attached:
- Data tabulated and assessed by the Ministry of Environment (MOE) are attached:
- On Nov 2, water quality results met applicable water quality guidelines (WQG) for the protection of aquatic life at the settling pond discharge, but there was a very minor exceedance of the copper WQG in the downstream receiving environment. However, the copper exceedance was an exceedance of the chronic guideline only, which should generally be applied to five weekly samples rather than a single sample result.
- On Nov 5, TSS exceeded the permitted limit of 25mg/L at the settling pond discharge and there were also minor WQG exceedances for total copper, total iron and total vanadium. At the SW-1 site, all parameters were below WQG except for total copper and total iron (note the context above for application of the chronic guideline for copper).
- Overall, all dissolved metals, which are the bioavailable form, are well below WQGs and results are not expected to pose a risk to the environment because WQG is generally conservative and there is significant dilution in Shawnigan Creek.
- All data has been shared with the Vancouver Island Health Authority so they can assess potential impacts to human health for downstream water users.
- Ministry staff will continue to monitor the situation and if necessary will take further action. This website will be updated if there are significant new developments or changes in site status.
November 8, 2016
- The permittee continues to report to the ministry that the actions required by the Order are being complied with and documentation is being provided in support of this.
- Photo of the site as of Nov 7, 2016 (JPG).
- Copies of data from water quality analyses conducted by the permittee are attached:
- Data tabulated and assessed by the Ministry of Environment (MOE) are attached:
- Slightly elevated levels of TSS, chloride and total iron in the settling pond discharge, and a very minor exceedance of the copper water quality guidelines in the immediate downstream receiving environment, are not expected to pose a risk to the environment because Water Quality Guidelines (WQG) are generally conservative and there is significant dilution in Shawnigan Creek.
- At the Weir Site, the TSS level exceeded the permissible limit of 25mg/L. All other parameters are below WQGs for the protection of aquatic life with the exception of chloride and total iron, which are slightly above the guidelines.
- At the SW-1 site, all parameters are below WQGs for the protection of aquatic life with the exception of total copper which just exceeded the chronic guideline – however, chronic guideline comparisons should be based on five weekly samples collected in 30 days, and this is a comparison using just one value. Chromium speciation confirmed that chromium was not an issue at the site on this date.
- Overall, all dissolved metals, which are the bioavailable form, are well below WQGs.
- All data has been shared with the Vancouver Island Health Authority so they can assess potential impacts to human health for downstream water users.
Ministry staff will continue to monitor the situation and if necessary will take further action. This website will be updated if there are significant new developments or changes in site status.
November 4, 2016
- The permittee continues to take action as required by the Pollution Prevention Order and provide supporting documentation to the ministry.
- Photo of the site as of Nov 4, 2016, is attached here. As of today, the welding of the liner continues.
- Ministry staff conducted an unscheduled inspection of the site on Friday, October 28 to assess compliance with the Pollution Prevention Order. The permittee was found to be in compliance with the Order. A copy of the inspection report is posted under “Correspondence” below.
- At the time of the inspection, a substantial portion of the Permanent Encapsulation Area (PEA) had been permanently covered with 40 mil LLDPE membrane, with work still in progress on the upper surface. Leak testing was scheduled.

- Elevated levels of TSS and a few metals in the settling pond discharge, and minor exceedances of water quality guidelines in the immediate downstream receiving environment, are not expected to pose a risk to the environment because Water Quality Guidelines (WQG) are generally conservative and there is significant dilution in Shawnigan Creek.
- At the Weir Site, the TSS level exceeded the permissible limit of 25mg/L. All other parameters are below WQGs for the protection of aquatic life with the exception of total chromium, cobalt, copper, iron and vanadium, which are slightly above the guidelines.
- At the SW-1 site, all parameters are below the WQGs for the protection of aquatic life with the exception of total chromium, copper, iron and silver, and dissolved aluminum. The dissolved aluminum concentration (and some other parameter) exceed the chronic guideline. Generally, chronic guideline comparisons should be based on five weekly samples collected in 30 days, and this is a comparison using just one value). Also of note is the fact that proper comparison of the chromium concentration to guidelines requires speciation, which is being done in the next sample from October 26.
- Overall, all dissolved metals, which are the bioavailable form, are well below WQGs except aluminum which slightly exceeds the chronic guideline only (see above note re: chronic guideline comparisons).
- All data has been shared with the Vancouver Island Health Authority so they can assess potential impacts to human health for downstream water users.
- Ministry staff will continue to monitor the situation and if necessary will take further action. This website will be updated if there are significant new developments or changes in site status.

- Ministry staff were on site today to verify compliance and will continue to monitor the situation and if necessary will take further action. This website will be updated if there are significant new developments or changes in site status.
October 24, 2016
- Over the weekend and this morning, the permittee continued to report to the ministry that the actions required by the Order were complied with and documentation was provided in support of this.
- There was no release of contact water over the weekend; all water was managed in accordance with the Order and permit requirements.
- Work commenced installing a permanent liner on top of the landfill. The East Slope Permanent Liner was installed on Saturday, the North Slope Permanent Liner was installed on Sunday, and a Qualified Professional will be visiting the site today to conduct a quality assurance inspection.
- Copies of data from water quality analyses conducted by the permittee are attached:
- Data tabulated and assessed by the Ministry of Environment and Climate Change Strategy (ENV)
- All data has been shared with the Vancouver Island Health Authority so they can assess potential impacts to human health for downstream water users.
- As per earlier web updates, elevated levels of a few metals in the settling pond discharge, and minor exceedances in the immediate downstream receiving environment are not expected to pose a risk to the environment.
- Toluene was found to be in exceedance of the BC Water Quality Guideline for Aquatic Health at both monitoring sites on Saturday, October 15th. ENV has been looking into this issue.
- Elevated levels of toluene are unusual at this site. As a follow-up, ENV contacted the permittee, who re-ran the lab analysis to rule out lab error; the second result was virtually the same as the original.
- A review of other data shows that Toluene was not elevated in the contact water sampled on October 14th and has not been elevated in the discharge results from sampling on October 16th, indicating the event was short-lived.
- Toluene is commonly found in association with benzene, ethylbenzene and xylene at similar concentrations, which was not the case on October 15th.
- Toluene is also a commonly used lab solvent and the analyzing lab is being queried as per their protocols to rule out the possibility of lab contamination.
Ministry staff will continue to monitor the situation and if necessary will take further action. This website will be updated if there are significant new developments or changes in site status.
October 20, 2016
- Site status as of 09:00hrs (JPG)
- The permittee reports today the actions required by the Order are still being complied with and that there are no significant changes in the status at the site
- The ministry has received and reviewed the results of sampling conducted by the permittee on October 15 and 16 at the settling pond outlet and in the creek immediately downstream of the discharge point. Samples for metals and organics showed that:
- There were slightly elevated levels of total chromium in the settling pond discharge. However, data indicates water quality guidelines for the protection of aquatic life were met in the receiving environment for this parameter. Total copper levels were slightly above the chronic water quality guideline in the receiving environment, but in general, single samples should not be relied on to compare to chronic (long term) guidelines.
- There were no exceedances in dissolved metals at the discharge point or in the receiving environment, which would generally be of greater concern given this is the biologically available form
- All organic results appear to be below detection limits with the exception of Toluene which was elevated on October 15th. The ministry and the permittee are both looking into the cause of this spike. However, significantly lower results on the 14th and 16th suggest there was/is no immediate risk to the downstream environment or water users
- Downstream risks are further ameliorated due to ongoing dilution in the receiving environment
- The ministry continues to share all data with Island Health so they can assess potential impacts to human health for downstream water users
- Ministry staff will continue to monitor the situation and if necessary will take further action. However, this website will only be updated if there are significant new developments or changes in site status

- Site status as of 10:00hrs (JPG)
- The permittee reports that as of 14:00hrs today the actions required by the Order are still being complied with. Supporting documentation has been submitted that shows:
- Approximately 18mm of rain has fallen at the site today
- The landfill cover is in place and remains effective (see above photo)
- The water management systems are maintained and operational
- Contingency measures are in place
- Documentation of inspections and monitoring were provided
- The ministry has received some preliminary results of sampling conducted by the permittee yesterday (Oct. 14, 2016) at the settling pond outlet and in the creek immediately downstream of the discharge point. Samples for metals and organics showed that:
- There were elevated levels of a few metals in the settling pond discharge (iron, chromium, copper and zinc). However, data indicate only very minor exceedances of water quality guidelines for the protection of aquatic life for chromium and copper at the creek sampling site in the receiving environment
- There are no exceedances in dissolved metals at the discharge point or in the receiving environment, which would generally be of greater concern given this is the biologically available form

South Shawnigan Creek monitoring study
In response to concerns expressed by members of the community about water flowing off the site in the fall of 2015, the ministry commissioned an independent watershed monitoring study for the South Shawnigan Creek area. The purpose of the monitoring study is to provide an independent, third-party assessment of water quality in South Shawnigan Creek, including areas downstream of Lots 23 and 21 on Stebbings Rd. An independent qualified professional was selected to design and implement the study, which was developed with input from a group consisting of Cowichan Valley Regional District, Shawnigan Residents Association, Cowichan Tribes, Vancouver Island Health Authority, Ministry of Energy and Mines, and Environment Canada. Sampling began in July 2016 and was expected to continue for approximately one year. Reports and documents are posted below.
