Pre-submission conference sign in AMAX Coal.pdf

This is a pre-submission conference sign-in document and notes from the Illinois Department of Natural Resources (IDNR) for the AML 2419 Amax Coal Culvert Reclamation Project (Project Number AML-IFuE-2419), held on March 4, 2026, at the project site approximately 1,000 feet west of 4633 E. Quarter Road in Ipava, Illinois. The project involves removing two severely deteriorated corrugated metal culverts and replacing them with 84-inch HDPE smooth interior Class 40 pipe culverts, stabilizing stream banks with riprap installation, constructing a temporary cofferdam for flow control during construction, and performing associated grading and erosion control work. The conference covered critical work specifications including construction signage requirements per sheet 7 of plans, cofferdam construction using aggregate, work pads, temporary culverts and pumps, riprap installation (RR4) with filter fabric but no bedding stone, and slope repair using excess excavated earth. IDNR personnel addressed bidding requirements including Business Enterprise Program (BEP), Prevailing Labor Agreement (PLA) compliance, and necessary bid attachments. The conference clarified that IDOT District 4 special provisions for aggregate quality apply to the project, that 30-degree mitered cuts on pipe culvert ends may be left square if the manufacturer cannot accommodate the angled cuts, aggregate backfill shall be used to 1 foot above the HDPE pipes and 18 inches on each sides, a 3-foot separation exists between parallel culverts, and straw blanket may be substituted for Mulch Method 2 as shown in the plans.

The pre-submission conference notes confirm that a full road closure is permitted under IDOT standards, requiring coordination with IDNR, the county, and Vermont Road District in advance. The conference occurred on the question submission deadline date of March 4, 2026, with bid submission scheduled for March 16, 2026. The contract term extends from the date of last signature through December 31, 2026, with work required to commence within 10 calendar days of contract execution. Design documentation identified Spirolite pipe supplied by ISCO Industries as the specified product, though the notes indicate other manufacturers and suppliers with products meeting the requirements are likely available. Bidders must be prequalified with the Illinois Department of Transportation and complete at least 51 percent of work with their own organization, with prevailing wage requirements mandating adherence to the Illinois Prevailing Wage Act and maintenance of 90 percent Illinois laborer employment during excessive unemployment periods. The contract includes a 1 percent BEP goal for minority, women, and disabled-owned businesses, and qualified bidders employing at least two current or former coal mine employees may receive preference consideration if their bid does not exceed 2 percent above the lowest bid.
