The state Department of Environmental Protection is giving a developer two weeks to address deficiencies in its geological report on the September landslide that closed Route 65 in Kilbuck, saying it lacks a plan to stabilize the site.

The 98-page report, ordered by the DEP on Oct. 3 and submitted Friday by DiGioia, Gray & Associates, consulting engineers hired by the developer, makes no attempt to analyze the cause of the landslide, or determine when or how the area will be stabilized.

"Our priority remains ensuring permanent site stability," DEP Southwest Regional Director Kenneth Bowman said.

The DEP delivered the deficiency letter to the developer, Kilbuck Properties LP, yesterday. The developer has 14 days to correct the deficiencies or face unspecified civil penalties.

"The developer has two weeks to provide the materials we initially requested. Then we'll do an assessment and an inventory to make sure the report is complete," said Helen Humphreys, a DEP spokeswoman. "Then we'll pursue other options if necessary.

"Only after we see what they return can we begin to evaluate any subsequent appropriate action."

According to the DEP, the developer's report is missing multiple elements, including core boring logs, analysis of data collected to measure the ongoing soil movement on the site and the permanent stability plan.

Although the developer requested and received a one-month extension to submit the geotechnical report, the document states that it has not had enough time to gather monitoring data necessary to produce a stabilization plan.

Neither Richard Gray, the engineer who signed the report, nor John Atwood, president of Kilbuck Properties, returned telephone calls requesting comment.

The landslide on Sept. 19 deposited approximately 500,000 cubic yards of dirt, rock and debris on Route 65, closing the major commuting route to Pittsburgh for almost two weeks and shutting down the Norfolk Southern railroad's main line for three days.

The state had ordered Kilbuck Properties to submit a "full and complete" geotechnical report detailing how the site will be permanently stabilized and proposing a schedule for accomplishing that goal.

Such a report should include a detailed characterization of the underground geology and surface features of the site, with an analysis of all earth-moving activities and their impact on the surrounding areas.

The consulting engineering firm submitted a 98-page report containing more than 80 pages of charts, graphs, maps, photos and measurement data, but just nine pages of text, much of it identifying slope survey monitoring points on the 75-acre former Dixmont State Hospital site.

The developer did meet the DEP's requirements that it submit daily monitoring data from the landslide survey monuments; the locations and elevations of rock trenches to anchor the toe of the slope; information about fill slopes and soil and erosion controls prior to the landslide; updated emergency erosion and sedimentation controls for the site and the off-site disposal area; logs of completed soil borings; and a preliminary evaluation of the rock bench below the stockpile.

Some of the data submitted shows that a portion of the High Point shopping plaza site is continuing to slide at a rate of three inches a week toward Route 65, also known as Ohio River Boulevard.

Three of the four lanes of Route 65 have reopened. One lane has been kept closed to traffic to provide a safety buffer in case the fill material should again begin moving rapidly.

DEP suspended Kilbuck Properties' erosion and sedimentation control permit for earth disturbance activities Sept. 22.

That suspension remains in effect, prohibiting any construction at the site except that related to site stabilization.
