Call to Order

Tom Fidler informed the Board that final revisions were made to the Chapter 250 regulations package and they are scheduled for presentation to the Environmental Quality Board (EQB) in May. Many of the comments that the Board suggested were incorporated in that package.

Kevin Reinert was unable to attend the meeting but he did provide comments on the Safe Fill Policy, and also Dr. Ron Neufeld was unable to attend but was available by phone.

Jim Snyder welcomed everyone in attendance, and stated that there will be other Safe Fill Policy presentations around the state. He reported that Deputy Secretary Denise Chamberlain made a presentation at the Environmental Law Forum, another presentation to the Pennsylvania Chamber. Also, meetings with the Environmental Subcommittee, three public meetings and hearings are scheduled. Jim stated that the reason we have to come up with a policy of this nature is that we’ve continued to get comments and questions from people from the banking institutions, from developers, from the scientific community, from a variety of folks asking how clean is clean, and where do we draw the line on what material may be used in an unregulated manner as fill. The existing policy was published in 1996 and this is a revision to that. The Department is very interested in the Board’s comments and also their recommendations as to how we can correct perhaps what it believes is either too liberal or too conservative.

Jim Snyder asked that everyone introduce himself or herself. He then introduced Bill Pounds to present the Department’s proposed Safe Fill Policy package. The following is a summary of the presentation he made using the attached PowerPoint slides.

The Department determined that all the concerns that were raised on the Fill Policy could not be addressed in one document. The Department decided that the best way to address the numerous issues raised was through a series of documents as well as some regulatory changes.

These documents and regulatory changes are:

The Safe Fill Policy is voluntary, and focuses on land development, not contaminated sites. Only soils that have no evidence of a spill or release, and therefore are not defined as a waste, qualify as Safe Fill.

Two sets of criteria may be applied to uncontaminated soils to make a Safe Fill determination.

Criteria I

The default level for metals is the lower of the estimated natural background level and the residential direct contact numeric value (RDC) from the Act 2 tables. For organics, the default level is the Estimated Quantitation Level (EQL), since such compounds do not normally occur naturally. The only organic substances that must be tested for are those on the short list of organic compounds for petroleum products found in the Act 2 TGM, plus five pesticides (aldrin, dieldrin, DDD,DDE,DDT).

Criteria II

For both metals and organics, if the levels exceed the Criteria I levels, a background determination may be made on the receiving site. If the levels are at or below background the material is unregulated. The background levels for both metals and organics are capped by the RDC. This is not the estimated natural background used in Criteria I but a site-specific background determination.

There is an exclusion from the Safe Fill Policy for less than 500 cubic yards of material to account for small landscaping projects, trenching for utilities, and residential basements.

The Permit by Rule is for certain kinds of contaminated soil and includes historical fill, soils contaminated by urban air pollution, and authorized pesticide use. The Permit by Rule is intended for materials that exceed the Fill Policy levels and allows material to be brought from a remediation site if it meets the range of values established in the Permit by Rule.

Beneficial Uses- Limited to

Bring onsite areas to grade to natural contours

Construction material

Control fire/mine subsidence

Reclaim abandoned mines (with approval)

Limitations and Conditions

Material must remain in place or be considered a waste

Not within 100 ft of perennial stream

Not within 100 ft of sinkhole

Erosion/sedimentation control plan

No odor/free liquids

Exclusively in areas zoned commercial or industrial

Numeric Criteria

For metals, the upper limits from existing General Permits. SPLP required to be below limits in Chapter 288.623

For organics, lower of RDC and lower of S/GW pathway values

The General Permit applies to the movement of contaminated material to Act 2 sites undergoing remediation. Cleanups qualifying for the General Permit will be under the Statewide Health Standard and an Notice of Intent to Remediate (NIR) will be submitted to the Department. The General Permit allows movement from one Act 2 site to another, and from a non-Act 2 site to an Act 2 site, but not from and Act 2 site to a non-Act 2 site. The only requirement is that the receiving site must be undergoing an Act 2 remediation (i.e., it has had an NIR filed with the Department). Act 2 soils cannot be moved to a fill site, even if it is demonstrated by sampling that the material meets the Fill numbers (because fill must have no evidence of a spill or release).

Beneficial Uses- Limited to

Bring areas to grade

Limit infiltration of rainfall

Limitation of runoff/erosion

Cannot be used as fill

Conditions

Receiving site similarly contaminated

Eco-screening

No odors/ free liquids

Promptly vegetate site

Dewasted as long as material remains in place

Requires 60-day comment period

Numeric values

For residential sites, numbers for organics compounds numbers are determined according to the Act 2 process. For metals, values are the RDC value.

For nonresidential sites, the values for organics and metals are the nonresidential direct contact values. For metals, SPLP also required.

A waiver of permits is available where waste is encountered as part of a remediation. This waiver allows the material to be handled onsite without a permit from the Department. It apples to a site being remediated under a site-specific standard, and thus requires an NIR. Performance standards apply for protection of human health and the environment, such as liners if appropriate.

The definition will be rewritten to exclude a conglomeration of soil and materials historically used as fill , including fly ash and slag. Material used prior to 1980 to bring an area to grade is not a waste if it remains onsite and a site-specific cleanup is performed. This does not include landfills, waste piles or impoundments. This A de-wasting process is written as occurring within the confines of an Act 2 cleanup.

The Board raised the following issues/concerns:

The Department asked the Board for its written comments. A two week period was agreed to. The Public Comment period will end in May. Ron Buchanan is was designated the chairperson for assembling the comments. Mark Urbassik made the suggestion that the Board members take one week to look over the Fill Policy and forward their comments to Ron. The next scheduled meeting is June 22nd.

The meeting was adjourned.
