Will County public hearing on proposed limestone quarry spotlights blasting, air and school‑safety concerns

A Will County Board public hearing on March 20, 2025, drew hours of testimony and large public turnout over zoning case ZC24‑066, a proposal by an applicant represented by Castle Law to open surface limestone mining east of Lily Cache (Lilycachet) Creek near Essington Road and Reagan Boulevard.

County and community officials and residents said the proposal matters because the site sits near established neighborhoods and Liberty Elementary School and because the operation would bring blasting, truck traffic and crushing closer to homes. Plainfield village and school officials, residents and outside experts pressed the board for clearer plans and tighter safeguards; the applicant’s team described multiple design changes and monitoring programs it says reduce risk.

Gary Davidson, an attorney with Castle Law representing the applicant, told the board the team “read each and every correspondence received by Will County,” removed underground mining from the filing and eliminated asphalt and concrete plants. Lead counsel Bill Graft said the applicant had withdrawn “almost 80%” of the original requests and presented new monitoring and berm designs. Graft and other witnesses said they had commissioned air monitoring (seven stations and a submitted report) and seismographic monitoring and would install a landscape berm that the applicant described as 30 feet tall with a 20‑foot flat top and roughly 200 feet wide along portions of the site.

The applicant also described other changes and conditions: a privately funded flood detention basin on the west side of Lily Cache Creek that the applicant said would store roughly 200,000,000 gallons and be used in part to build the berm; a site development permit process; and continued requirements for state and federal approvals on wetlands and floodway issues. The applicant’s engineers said surface blasting would be directed back into the quarry so material, dust and noise are contained inside the mined area.

Opponents and several expert witnesses disputed whether those changes eliminate the risks. Tim Martin, a mine‑safety consultant who testified for opponents, gave a history of documented fly‑rock and blast incidents nationwide, and said, “No mine ever intends for the rock to get away from the site … [but] a % method or a system to guarantee you a % that you’ll prevent fly rock does not exist.” Jason Turner, an economist who said he is a Bolingbrook resident and the chief investment strategist at a regional bank, testified that published studies show mines can depress nearby home values and estimated—using conservative assumptions—more than $70 million in lost residential value and more than $20 million in lost property‑tax revenue over a decade (his methodology and assumptions were presented to the board and are summarized in his testimony).

Plainfield Mayor John Arguelles and the superintendent of Plainfield School District 202 told the board the district opposes the proposal. The superintendent noted concerns about “fly rock,” air pollution, and effects on students with respiratory conditions; he said the petitioner had not met with the school district to address those concerns. Multiple parents, residents of the Lakelands and Americana Estates subdivisions, and other neighbors told the board they worried about proximity to Liberty Elementary, truck traffic on Essington and Reagan, dust, and long‑term property impacts.

Applicant witnesses gave technical details in response. Quick Supply Company engineer Chuck Palmcook said production blasts are designed to cast rock inward and that typical production blasts last milliseconds; the blasting expert described Will County’s vibration standard as half an inch per second—half the Illinois state standard of 1 inch per second—and said monitoring stations placed near the school and nearby homes had not registered readings above the county threshold during recent blasts. The applicant’s civil engineer (Landmark Engineering’s Mike Shamsie) and other staff said stormwater modeling for the detention basin shows reduced exit velocity at the modeled discharge point compared with predevelopment flows; they said county, state and federal approvals (including the U.S. Army Corps of Engineers and FEMA for floodway work) would be required before construction.

Several county board members asked for specifics: where berms and screening would sit relative to Reagan and Essington, whether berm construction would precede blasting in the new area (the applicant said yes), the timing and notice of blasts (the applicant said blasts are scheduled based on market demand and safety protocols with notices and perimeter controls but can shift for weather or safety reasons), and the frequency and duration of blasts (the applicant said roughly once or twice a month in winter and three to four times monthly in peak season, with a single blast event measured in milliseconds). The applicant said independent vibration and air monitoring contractors (including VibeTech for vibration monitoring) would be used and that monitoring records would be kept.

The board opened a formal public hearing at the start of the land‑use segment (roll call vote 21 in the affirmative). The hearing remains a public evidentiary process; no final vote on the special use permit occurred at the March 20 meeting. County staff and the Land Use Committee recommended denial in their written analysis; the applicant noted that the Land Use Committee had recommended approval of the original application earlier in the process and that the new filing withdraws many requests made previously.

Those opposed urged the board to deny the special use permit on the basis of the pattern of development, the proximity of houses and a school, unresolved questions about long‑term reclamation and access, and residual uncertainty about fly rock and air‑quality impacts. Supporters and union representatives said the quarry provides local jobs and urged the board to weigh the economic and workforce benefits and the applicants’ proposed mitigation measures. Several speakers asked the applicant to commit to additional community outreach; residents and some elected officials said outreach promised after an earlier meeting had not been completed.

The hearing record includes the applicant’s amended materials, an air‑monitoring report the applicant submitted, seismograph logs the applicant says were collected near Liberty Elementary and nearby homes, and written correspondence from residents. The board signaled it will continue to accept testimony and review technical material. The matter will return to future committee and full‑board consideration after the public‑hearing record is complete and staff review of revised documents finishes.

Ending: The public hearing remained open at the close of the March 20 session; the board did not take a final zoning vote. Board members, staff and the public said they expect follow‑up items—additional technical data, modeling and more outreach—before any final decision is placed on a future agenda.
