MSDS sheets - Attached is a� MSDS for crushed asphalt and concrete. <br />2. Expected emissions from Rose�ifle plant utilizing warm mix asphalt technology. I have attaclled an <br />err�issions table that shows 20Q8 emissions from our three asphalt plants plus a column For <br />expected emissions from our proposed Roseville plant. <br />3. No stormwater infiliration. If infiltration used, insiafE groundwaier monitoring wells. Attached <br />are applicable portions of the Rice Creek Watershed rules. WhiEe the rules show a preference to include <br />infiltrafion as at least a portion of the design, there is some language allowing ap�ro�al with no ir�filtration, <br />esp�cially in the case of existing contamination. It appears we can meet the Rice Creek rules without the <br />use of infiftration by s�ightly modifying the 5outh Wet Pand {increas� in normai water ele�ation) and making <br />the proposed infiltration area within the tanker #ruck t�rning cirde a wek pond. We have had preliminary <br />discussions with the Watershed and will be meeting with them on ih�trsday of this week. Our <br />understanding is they will be open to alternative ideas and the ]esser use of infilfration given the ather <br />canstraints of our site and use. <br />4. Storxnwater Reuse (cansider) - We will f�rther investigate this as construction plans are de�eioped, <br />One idea might be to install a manhole adjac�nt fo the fot behind the maintenance buifding, with a pipe to <br />draw from a point several feet below the water surface and above the bottom. f nstallakion af an electric <br />pump in this sump could allow us to fill trucks far on-site watering while minimizing issues wi#h floatables <br />andlor sedirnent tF�at can become an issue in water re-�se. <br />5. Trackaut Control (consider) - We plan ta make provisions on the site to accammodate a wheel wash <br />system sametime in ihe future. This wash or process water will be kept as a separate sysfem fron-t <br />stormwaker. The pavement draining ta this system wilf be minimized to a�oid overwhelming the settlement <br />and treatment cells, washing tne waste ouf with starmwater. <br />6. Backup alarml fai! gate noise (coniingency plan) - Tailgate noise can be mit�gated by pasting sigt�s <br />instructing our trucks not to bang their tailgates. Backup aiarms are indeed requir�d by OSHA but <br />the one in the link below erriits a sound like a cat scratching against a wall and dissipates quickly <br />with distance. <br />Ilttp :ll www. reverseinsafety, ca.uk/news-letters/noise-news.ht�xil <br />7. Mechanical dust contro[ (contingency plan} — We will have to investigate this further. Keep in mind that <br />we are proposing fance and landscape screening along the perimefer of the property. <br />Sincerely, <br />Kent Peterson <br />Bituminalls Roadways, Inc. <br />6f1 Of2009 <br />
