Molin Concrete page 7 9. All applicable MPCA requirements are satisfactorily met. comment: MPCA has rules regarding underground fuel tanks and stormwater management for water quality. Molin states that there are regular inspections of the tanks by an outside firm, which submits reports to MPCA. A new stormwater plan for the site is pending. The noise issue is the greatest concern. The Minnesota Pollution Control Agency (MPCA) does have noise standards. This issue is discussed in greater detail below. 10. All proposed structures comply with applicable City building material requirements. comment: Building permit review has assured this. The Building Official has no outstanding building material issues. 11. The following noise mitigation efforts are utilized: a. Concrete product (precast wall panels) are stored parallel to the northerly buffer yard to act as a sound buffer. comment: Molin is requesting that this condition be deleted (see Molin letter). Not all products stored in the northern area are wall panels. Molin typically stores wall panels both laying flat and stacked. The berm is a better insulator than the wall panels. Storing panels parallel to the berm will increase the amount of time the equipment would need to move them. This could increase the noise level for the neighbors. Storage of product is not a reliable means of mitigating noise. Staff recommends deleting this condition. b. The outdoor storage yard is arranged such that truck backing maneuvers toward residential properties are minimized. comment: It may be difficult to ensure this can occur, depending on product mix and volume. However, Molin has stated that they attempt to do this and they have not requested the removal of this condition. c. Molin equipment and trucks shall be outfitted with strobe lights to replace backup beepers during nighttime hours (6:00 p.m. to 8:00 a.m.). comment: The use of beepers versus strobe lights has been the topic of much discussion. Molin recently received a letter from Minnesota OSHA stating that training and strobe lights proposed to them by Molin is acceptable under the law.
