Are you ready for Ontario’s Excess Soil Management Regulation Changes?

by David Ngugan, Staff Writer

A breakfast and seminar session organized by ECOH Management Inc. was held on June 20th in Mississauga, Ontario.  The seminar included a presentation by Vice President Jeff Muir titled “Digging Deep – Are you ready for Ontario’s Excess Soil Management Regulation Changes?” about the upcoming changes to the Excess Soil Management Regulations. He spoke about the implications of the new regulations, including cost, the depletion of sites with capacity to accept waste soils, illegal dumping and lack of tracking, and inconsistent oversight and criteria for the management of excess soils.

Jeff spoke about the current 2014 guidelines – “Management of Excess Soil – A Guide for Best Management Practices” that gives options for the management of excess soils both onsite and offsite,  as well as best management practices for project leaders. These include having an excess soil management plan to indicate where the soil will go and a sampling and analysis plan, including soil characterization and characterization of the receiving site.

He also pointed out some issues with the guidelines, particularly in the lack of clarity regarding who is responsible for the excess soil, as the term “project leader” is loosely defined. In addition, the requirements for proper characterization of soils are not clearly defined, such as a minimum number of samples required for a specific volume of soil. Jeff added that currently, many receiving sites are usually managed by municipalities that issue permits for the receiving of excess soil, and this presents opportunities for inconsistencies between various sites.

The proposed regulations enhance the responsibility and accountability of the generators of excess soil, as well as requiring an Excess Soil Management Plan (ESMP) for high risk or high volumes of soil. Under the proposed regulations, a ESMP should consist of a description of the project area and description and ownership, the names of qualified persons and contractors, excess soil sampling plan and characterizations, a list of receiving sites, a soil tracking system, and a record of the cumulative amount of soil moved.  The new regulations will also establish a registry where ESMPs will be submitted.

Jeff concluded his presentation by stressing the importance of preplanning – have all the costs, receiving sites, and estimated volumes of soil prepared ahead of time, as well as to focus on working with ESMPs well ahead of the promulgation of the regulations.  It is anticipated that the regulations will be promulgated this calendar year.

Ontario Graphite Ltd. Subject to Control Order Issued by Environment Ministry

The Ontario Ministry of the Environment and Climate Change (MOECC) recently issued an Emergency Director’s Order to Ontario Graphite Ltd. (OGL) related to its mining site in Butt Township, Kearney, Ontario.  An Emergency Director’s Order is issued when the MOECC is of the opinion that inaction of a situation can result in one or more of the following: danger to the health or safety of any person; harm or serious risk of harm to the environment; or injury or damage or serious risk of injury or damage to any property.

Under an Emergency Order, immediate actions and environmental actions must be taken to protect the natural environment and to prevent or reduce the discharge of a contaminant into the natural environment from the undertaking or property, or to prevent, decrease or eliminate an adverse effect.

Kearney is a town and municipality in the Almaguin Highlands region of Parry Sound District of Ontario, Canada.  With a landmass of 531 square kilometres and a year-round population of 882 in the Canada 2016 Census, Kearney claims to be the “Biggest Little Town in Ontario.”  Butt Township was amalgamated with the Town of Kearney in 1979.

Since the issuance of Director’s Order Amendment No. 1 Ontario Graphite Limited (OGL) has reported to the MOECC multiple exceedances of discharge limits specified in the Environmental Compliance Approval (ECA) issued for the Kearney Mine industrial sewage works and Ontario Regulation 561/94 (i.e. including exceedance of limits for acute toxicity to test organisms Rainbow Trout and Daphnia magna, iron, total suspended solids and pH).

As requested by the MOECC, OGL proposed a short term management action plan to address the effluent discharge limit exceedances from the polishing pond until such time that construction can be completed on the industrial sewage works to enhance treatment efficiency once approved by the MOECC through an ECA amendment. OGL further indicated to the MOECC that an application to amend the ECA for necessary modifications to the industrial sewage works is currently being prepared.
Following the MOECC’s review of the short term management action plan and monitoring data submitted by OGL, the MOECC is concerned that measures proposed by OGL will be insufficient in achieving adequate treatment until such time that construction and operation of the proposed modification to the industrial sewage works, subject to the planned application and subsequent approval by the MOECC, if issued, are completed.

Currently, the lime dosing system being used at the Kearney Mine as part of the existing industrial sewage works operation is operated on a batch basis over, typically, an eight hour period during daylight hours.  The enhanced pH monitoring and reporting required by the January 31, 2018 Director’s Order amendment has demonstrated that the pH of the discharge is not consistently meeting the required pH range over a 24 hour period.  Therefore, the MOECC is directing that the operation of the batched system be extended over a daily, 24-hour period to ensure compliance with pH at all times.

In addition to adjusting the lime dosing system the MOECC is ordering a contingency plan be developed to including the use of an approved mobile treatment unit to ensure adequate treatment is achieved if proposed measures are not sufficient in achieving compliance with all discharge water quality limits until such time that modifications, approved through an amendment to the ECA, are implemented.

In summary the Emergency Director’s Order requires OGL to do the following:

  • Conduct an enhanced monitoring program for pH.
  • Ensure that the operation of lime dosing system is supervised by a Qualified Person and that effluent is maintained within a pH range of 6.5 – 8.5 at all times.
  • Retain a Qualified Person to develop and submit a contingency plan to treat the Kearney Mine polishing pond waters.
  • Retain a Qualified Person to submit an amendment to the issued Industrial Sewage Works, Environmental Compliance approval.

The Order was served to the company as well as a number of a company director, the CFO & CAO, and the CEO.
