In conjunction with remediation projects, many property owners are recording Restrictive Covenants which set forth limitation on the future use of the property. Pursuant to MCL 324.20114(c), a copy of the recorded Restrictive Covenant that is part of a post-closure plan or an MDEQ approved remediation must be filed with the MDEQ.

Provisions of the Restrictive Covenant may include limitations on future use such as installation of drinking water wells, testing of soils during development, maintaining exposure barriers, restricting site use for commercial or industrial purposes only. The Restrictive Covenant constitutes one element of giving public notice on the limitations of the property.

This online database is available on the MDEQ web site under “environmental mapper” which can be accessed here. The database can be searched by city and county. Sites can be identified within a radius of a specific location.

It has been a concern of MDEQ that without plotting this information and reporting use restrictions, the Agency has never had a complete inventory on all the parcels within the state that may be subject to certain future use restrictions. This inventory also provides an accounting of sites subject to continuous inspection and monitoring.

This source of information may also prove to be a helpful tool for prospective purchasers that undertake Baseline Environmental Audits or Phase I Environmental Audits. We would anticipate that this database will take several years to be comprehensive or reliable as an investigative tool.

The following is a transcript of my interview with Gary on Groundwater/Surfacewater Interface (“GSI”):

Q 1. You have followed the issue of GSI for many years. Please give us a brief overview of what GSI is and what is the scope of this exposure pathway?

GSI in the context of contaminated properties is a potential exposure or hazard pathway at locations where site groundwater provides a transport mechanism to move hazardous substances into surfacewater. It is not a relevant pathway at all properties but is frequently the case at hundreds if not thousands of Part 201 and Part 213 sites in Michigan. Michigan’s site remedial action program has for years required groundwater quality to meet standards established to protect surface water resources, and these standards, along with drinking water standards, regularly determine whether or not groundwater cleanup is required. Because it is often the case that potential drinking water pathway hazards are addressed by imposing restrictions on the use of site groundwater as a water supply source, the “GSI” criteria regularly becomes the most challenging (and costly) aspect of completing site cleanup obligations.

As GSI focuses on the “interface” between groundwater and surface water, variable groundwater, and particularly surface water, hydrologic factors (flow, elevations, etc.). At sites in Michigan, the GSI is often a dynamic transition zone between groundwater and surface water. Within this zone various geochemical and biological reactions can be acting to transform the nature of substances originating from upland locations.

Q 2. MCL 324.20120e sets forth Michigan’s statutory requirements regarding “Groundwater Venting into Surfacewater”. Under the current statute, what problems has the regulated community had with complying with this exposure risk pathway and criteria?

The generic criteria for the GSI pathway is the most stringent of all the Part 201 groundwater cleanup criteria, along with the drinking water pathway criteria. But in many cases drinking water exposure is not an exposure pathway of concern due to available alternate water supplies at the sites, so the GSI criteria routinely determines what can be a sufficient completion endpoint for closure for Part 201 sites.

I characterize two primary problems in complying with the GSI pathway and criteria as:

(a) the application of a “permitable surface water discharge paradigm” to the decision making relative, to the need for a groundwater cleanup to protect surface water resources; and

(b) the application of the GSI criteria in groundwater near sewer systems even when there is no chance for substances at that location to adversely impact surfacewaters.

The “permitable surfacewater discharge paradigm” evaluates groundwater venting to surface water as if a groundwater plume is a point source discharge for which an NPDES permit would need to be issued. The consequences of this approach have been that surfacewater quality standards that are meant to protect surfacewater flora and fauna have to be met in the groundwater even though no such resource exists at that location. This has been a large barrier to getting cleanups completed because parties are unwilling to invest the resources necessary to meet standards for which there will not be any demonstrated environmental improvement and benefit.

Q 3. You have been involved with multiple discussion groups regarding these problems with regulating the GSI pathway. Are there any groups currently reviewing statutory revisions that would affect the GSI pathway regulations or criteria?

There are two recent efforts: one is the review by the Office of Regulatory Reinvention that was initiated per the Governor’s Executive Order in 2011. The second is the Collaborative Stakeholders Initiative (“CSI”) that was initiated by the MDEQ at the start of this year. Follow up on the recommendations of those two efforts is continuing. (The recommendations are summarized here.) Draft amendments to Part 201 to address these issues and this pathway have been developed and are poised for consideration by the legislature. (A recent version of the draft legislation appears here.)

Q 4. Can you provide us with a brief overview of the overall goals of your CSI issue group, in proposing revisions to MCL 324.20120(e)?

The overall goal of our work group was to revise and improve the way the GSI pathway is addressed in order to facilitate closure and final cleanups, rather than the pathway being the issue that prevents closures and completion of actions.

Q 5. How would these proposed changes affect the efficiency and reliability of site remediation?

It will be possible to more efficiently reach appropriate decisions as to the need for groundwater cleanup to protect surfacewater resources. As a result, there will be earlier and sooner closure of site cleanups and a better return on investments and stewardship of legacy site conditions. There are certainly hundreds to thousands of sites that face this issue.

Q 6. What is your understanding as to the status of any legislative efforts to pass a statutory change to GSI?

There is a very good prognosis for future legislative action to address the issue, perhaps even before the summer recess of the current legislature. I understand there is at least one sponsor of the legislation of potential amendments that has been identified. .

Q 7. What might these proposed statutory changes mean to the regulated community if they’re passed?

In my mind it means that many long-standing, unresolved site cleanups could be brought to a closure with a reasonable investment of additional resources. The key will be Remediation Division recognizing the “permitable surface water discharge paradigm” is not applicable to decision-making for this pathway, a position acknowledged by MDEQ and stakeholders participating in the CSI.

Q 8. What sites do you think would benefit the most from this statutory change?

Any sites that are unresolved due to the groundwater/surfacewater interface pathway. This is certainly the case most often at sites that are adjacent to rivers, lakes and other waterways of the state. It will also include many sites that have been held up on this issue even if they aren’t near a waterway, but they happen to be near an indirect conveyance to waterways such as storm and sanitary sewers. These sites have essentially been held hostage to the old approach on the issue, for which the proposed legislative changes provide a much better basis for appropriate protection of surface water resources along with completing site cleanups.

Q 9. What were the big highlights of the recommendations that came out of your CSI issue group?

There were several. The recommendations include

(1) The addition of two other methods for evaluating whether or not there is a need to do groundwater cleanup to bring a site to closure relative to the GSI pathway by:

• Performing an ecological evaluation of the surfacewater conditions;
• Performing an modeling evaluation to determine the potential for adverse impacts to the surface water.

(2) Focus evaluation of conditions relative to indirect pathways to surfacewater such as via storm and sanitary sewers based upon whether or not the groundwater contamination has the potential to adversely impact the surfacewater resources, instead of focusing on whether or not the groundwater may enter the stormwater sewer at a concentration above surfacewater standards.

(3) Evaluate conditions relative to mercury based upon laboratory methods which achieve a quantitation limit of 0.2 ppb rather than the methods developed for ultra-low detection limits. This will assure that significant sources of potential release of mercury from groundwater into surfacewater are addressed. This will avoid having to address cases where mercury is detectable, but concentrations are so low that there really isn’t any benefit in investigating them further.

Q 10. What do we hope to see over the six months?

We hope that the legislation is enacted to affirms a sound scientific foundation and public policy for making decisions about whether cleaning up groundwater is needed to protect a surfacewater resource. This would put into practice evaluating the potential impacts to surfacewaters based upon the actual surface water impact rather than conditions in groundwater having to meet surface water quality standards.

What remains to be seen after such a foundation is laid out in the statute is exactly how that ends up being implemented by the agency. One issue not fully sorted out that may end up being an impediment to swiftly addressing the GSI issues is the issue of securing MDEQ’s approval for using the alternative methods proposed to be enacted in the statute.. The CSI work group wrestled with this a bit, but so far the proposal does not encompass any real changes from existing protocols for parties needing to secure MDEQ approval. There will certainly be ample opportunity to see how things actually work out, and whether or not the requirement for MDEQ approvals in certain cases ends up being an additional step that causes further delays in achieving closures at sites.

I’d like to thank Gary Klepper for providing this information on the status of proposed changes to Part 201 and regulation of the GSI in Michigan. We will continue to watch this issue as it evolves over the next 6 months.

In support of the Governor’s goals, the MDEQ has partnered with stakeholders to formulate a plan for improvements in Michigan’s environmental programs. This effort is referred to as the Collaborative Stakeholders Initiative (“CSI”). CSI grows out of a series of recommendations prepared by the Office of Regulatory Reinvention and that was submitted to the Governor’s office.

Participants in CSI are taking a closer look at seven key issues facing Michigan’s cleanup and redevelopment programs. They include:

(1) Groundwater and Surfacewater Interface (GSI) pathway;

(2) Cleanup criteria;

(3) Vapor intrusion;

(4) Free product, source removal and Csat;

(5) Brownfield redevelopment;

(6) Part 201 Rules/Operational Memorandum Guidance; and

(7) Due care obligations.

As a backdrop to reviewing these issues and developing recommendations, participants also hope to derive the benefits of an opportunity for exchange and cooperation between the MDEQ, the regulated community and other public stakeholders. Each issue subgroup is in the process of refining their recommendations and developing action plans after having completed several intensive sessions both in Lansing and during a three-day working program at the Kellogg Biological Station on Gull Lake. There will be a public session to present these recommendations on March 15, 2012.

The action plans will include recommendations with respect to Part 201 and Part 213, Part 201 Rules, applicable Operational Memorandums, Guidance Documents, and other policies affecting the implementation of these programs. There will be an opportunity learn more about these recommendations and action plans during a webcast scheduled for March 15, 2012. More details on connecting to the webcast to follow.

As someone involved in the CSI process, it is my belief that the process and this initiative has the potential for being extremely beneficial, and may lead to many changes within Michigan’s cleanup and redevelopment program that will facilitate expedited cleanups and redevelopment while protecting the environment.
