Section 306 requires an FDR mix with 100% of the material passing the 2‐inch sieve, but the specified pulverizing equipment does not possess a mechanism that produces this.

Standard construction equipment can produce a mix with a maximum 3‐inch material size, so we request that the Government change the material specifications for the FDR mix to allow for 100% of the material passing the 3‐inch sieve and 95% of the material passing the 2‐ inch sieve, since these are the requirements

Would the Government consider removing the phrase “in the shade” from the specifications and/or reducing the minimum air temperature to 45°F, as specified in the ARRA
