At 1332 hours 50 and 54 were sent to 1402 Eshelman Mill Rd for a reported brush fire. Upon response County Communications advised of several calls for the mulch piles smoking at Witmer Mulch. Deputy 50 (D Reese) arrived with two large piles of mulch smoking and requested additional tankers to assist. Engines from 50 and 54 laid back the lane and Tower 50 set up next to the pile to deluge it. Two fill sites were established for tankers and after approximately an hour the fire was extinguished. Thanks to all of our mutual aid companies for the assist and to Tanker 43 for the standby.
