Decision summary

We’ve made amendments to the Wells Regulation to reduce administrative burden for the well construction industry, while maintaining protections for the environment, human health and public safety, and consumers.

Decision details

On October 28, 2019, the Ministry of the Environment, Conservation and Parks posted proposed amendments to the Wells Regulation (Regulation 903) under the Ontario Water Resources Act for a 30-day comment period. The purpose of the amendments to the Wells Regulation is to:

  • modify minimum insurance requirements for licensed well contractors to match insurance policies available in the marketplace
  • update well casing specifications to harmonize with international standards
  • allow placement of shallow well screens for long-term test holes and dewatering wells

A decision was made to proceed with the amendments to the Wells Regulation consistent with the proposal as described, with the following changes:

  • Updating Well Casing Standards - NSF/ANSI 61, “Drinking Water System Components – Health Effects” has been designated as a National Standard of Canada by the Standards Council of Canada and renamed NSF/ANSI/CAN 61, “Drinking Water System Components – Health Effects”. The Wells Regulation has been amended to reflect the new name of this standard.
  • Allow Placement of Shallow Well Screens for Test Holes and Dewatering Wells – Section 14.4 of the Wells Regulation, subsection (4) is amended to delete reference to subsection “(3)” and replace it with subsection “(3.1)”.
  • Amending regulation comes into force on the later of January 1, 2020 and the day it is filed.

The amending regulation was filed with the Registrar of Regulations on December 19, 2019 and will come into force on January 1, 2020.

Effects of consultation

Public consultation took place on this notice from October 28, 2019 to November 27, 2019.

In total,16 comments were received.

The proposed amendments were supported by the well construction industry, municipalities and the insurance industry. No comments were received that opposed the proposed amendments. However, one environmental group was critical that the government has not made more significant changes to further regulate well construction and decommissioning.

One stakeholder identified an unintended drafting issue to the proposed changes that would allow test holes and dewatering wells to be constructed to access shallow groundwater. To clarify the matter, the proposed final regulation would amend subsection 14.4 (4) to address this unintended issue, supporting the original intent of the proposed policy change.

A number of stakeholders provided comments which are unrelated to the proposed amendments. While not part of the decision on this proposal, the ministry will consider these policy and program suggestions as part of its regular business.

Proposal details

Description of regulation

We are seeking public input on proposed changes to the Wells Regulation (R.R.O. 1990, Regulation 903 under the Ontario Water Resources Act) to reduce administrative burden on the well construction industry, while maintaining protections for the environment, human health and public safety, and consumers.

The Wells Regulation sets out requirements for:

  • constructing, maintaining and abandoning wells
  • licensing well contractors (businesses) and well technicians

The Wells Regulation and the Ontario Water Resources Act apply to:

  • water supply wells (e.g. private, municipal, agricultural, commercial, industrial wells)
  • dewatering wells
  • test holes

The proposed amendments to the Wells Regulation would:

  • modify minimum insurance requirements for licensed well contractors to match insurance policies available in the marketplace
  • update well casing standards
  • allow placement of shallow well screens for test holes and dewatering wells

The proposed amendments are expected to make it easier for the well construction industry to operate by reducing administrative burdens and aligning with current international standards, while maintaining protections for the environment, human health and safety, and well owners. This includes municipalities, agri-industry, businesses, institutions, and land owners.

Purpose of regulation

The purpose of the proposed amendments to the Wells Regulation is to:

  • modify minimum insurance requirements for licensed well contractors to match insurance policies available in the marketplace
  • update well casing specifications to harmonize with international standards
  • allow placement of shallow well screens for long-term test holes and dewatering wells

Details of the proposed amendments

Modify Minimum Insurance Requirements for Licensed Well Contractors

The Wells Regulation sets out minimum insurance requirements for licensed well contractors.

We are proposing to clarify in paragraph 2 of section 4 of the Wells Regulation that licensed well contractors must maintain third party general liability insurance, including bodily injury, personal injury, property damage and products and completed operations, with a limit per occurrence of not less than $2,000,000, and an annual aggregate limit of not less than $5,000,000. We are also proposing to remove the maximum deductible requirement to provide well contractors with more flexibility in selecting insurance policy options that are right for their business and customers.

Update Well Casing Standards

Subsection 13(16) of the Wells Regulation sets out minimum specifications for well casing for constructing new water supply wells. We are proposing to revise the casing specifications to ensure that well casing materials meet up-to-date international standards and match what is currently available in the marketplace. The full titles of the international standards documents would be added to the regulation for ease of reference. The phrase “as it may be amended from time to time” would be added so that as referenced international standards are updated by their authoring organizations, the latest version of the standard would apply, subject to the ministry informing the public of updates. The documents referred to in the regulation would also be on file in the office of the ministry in Toronto.

We are also proposing to delete the provision in the Wells Regulation that requires ‘high yield wells’ (e.g. municipal and industrial wells) to meet the casing specifications in Table 2 in AWWA A100-06 “Water Wells”. Instead, the casing standards found in Table 2 in AWWA A100-06 will be listed directly in the Wells Regulation as additional options for steel and plastic casing. This would allow the well technician to exercise professional judgment when selecting casing for high yield wells.

Accordingly, we are proposing to add the following additional options for steel:

  • Grade B pipe, ANSI/AWWA C200, “Steel Water Pipe 6 Inch (150 mm) and Larger”
  • Carbon steel pipe, API Spec. 5L, “Specification for Line Pipe”
  • Carbon steel, Grade B pipe, ASTM A139/A139M, “Standard Specification for Electric-Fusion (Arc)-Welded Steel Pipe (NPS 4 and Over)”
  • Copper-bearing steel, Grade B pipe, ASTM A139/A139M, “Standard Specification for Electric-Fusion (Arc)-Welded Steel Pipe (NPS 4 and Over)” and the steel must contain a minimum of 0.20 per cent copper.
  • High-strength, low-alloy steel, Type 4 pipe, ASTM A606/A606M, “Standard Specification for Steel, Sheet and Strip, High-Strength, Low-Alloy, Hot-Rolled and Cold-Rolled, with Improved Atmospheric Corrosion Resistance”
  • Stainless steel pipe, ASTM A778/A778M, “Standard Specification for Welded, Unannealed Austenitic Stainless Steel Tubular Products”

Similarly, we are proposing to add the following additional option for plastic casing:

  • Plastic casing, ASTM F480, “Standard Specification for Thermoplastic Well Casing Pipe and Couplings Made in Standard Dimension Ratios (SDR), SCH 40 and SCH 80”

The proposed amendments would also allow for small diameter plastic casing to be used if it meets international standard ASTM F480, “Standard Specification for Thermoplastic Well Casing Pipe and Couplings Made in Standard Dimension Ratios (SDR), SCH 40 and SCH 80”, as it may be amended from time to time. ASTM F480 includes minimal wall thickness for a range of pipe sizes and is a recognized standard used by several other jurisdictions in Canada and the United States.

Allow Placement of Shallow Well Screens for Test Holes and Dewatering Wells

Paragraph 14.4(2)3 of the Wells Regulation currently does not allow a well screen to be installed shallower than 2.5 metres below the ground surface.  In some situations, however, such as for water quality monitoring, or removing of contaminants near to the surface to support Brownfield redevelopment or remediation of contaminated sites, a well screen for a long-term test hole such as a monitoring well or a dewatering well needs to be placed where it intersects the water table, which could be closer to the ground surface than 2.5 metres.

We are proposing to amend the Wells Regulation to allow for the placement of shallow well screens when constructing test holes and dewatering wells, which are not scheduled to be abandoned within 180 days after completion of the structural stage, to be installed at depths of less than 2.5 metres below the ground surface.

Section 14 of the Wells Regulation would still apply, which requires that the person constructing the well shall ensure that any annular space, other than the annular space surrounding a well screen, is sealed to prevent any movement of water, natural gas, contaminants or other material between subsurface formations or between a subsurface formation and the ground surface by means of the annular space.

Timing

We are proposing that the amendments to the Wells Regulation would come into effect upon filing, which is anticipated to be early 2020.

Regulatory Impact Statement

The proposed amendments are expected to make it easier for the well construction industry to operate by reducing regulatory burdens. Overall, the proposed changes will reduce current administrative burden by:

  • clarifying requirements
  • providing more flexibility to well contractors in the choice of materials used for casings
  • aligning insurance requirements to what is available in the marketplace for well contractors

Minimal administrative costs may be incurred to account for time needed by well contractors and well technicians to read and understand the regulatory changes, should they be approved.

The proposed updates will likely benefit well owners, such as municipalities, agri-industry, businesses, institutions and land owners by modernizing requirements for well construction activities.
