​Will the quarry affect my commute?

​​Most likely. Highway 7 is the main commuting thoroughfare and it is also the proposed haul route, eastward through Acton towards the GTA according to the plan in the application.  Trucks will be running from 6 am to 6 pm, coinciding with the busiest commuting times.  The 6th Line Eramosa – Hwy 7 intersection will be a pinch point as heavily loaded trucks try to turn left onto Hwy 7 and accelerate up to the 80 kph limit–you know how long that takes.  Nassagaweya 5th Line, a 20 metre jog south and east of Eramosa 6th Line will also be seriously impacted. By the way, there is no guarantee that truck traffic won’t end up going west through Rockwood to serve markets west of here, such as the new Hwy 7 construction planned between Guelph and Kitchener or other Wellington County projects. Finally, there is also no guarantee that, in spite of JDCL’s assurances, trucks won’t use the Nassagaweya 5th and 6th lines to avoid going through Acton.  Your commute certainly won’t get better!

​Will there be more truck traffic through Rockwood?

​​It is certainly possible.​ Though JDCL claims there won’t be, they were unwilling to fix their incomplete and misleading haul route study and took their application to the OMB instead online-apteekki.com. JDCL has also changed haul route projections in its application, and recently indicated to Wellington County that Hidden Quarry aggregate would be available to the County, ie. north of Rockwood.  Twenty years is a long time to be able to predict where aggregate markets might be.  In addition to general demand, the proposed twinning of Highway 7 between Guelph and Kitchener/Waterloo will be looking for aggregate so it is not unreasonable to expect a significant increase in truck traffic through Rockwood over to Guelph.

​Will we feel the blasting?

​​A large part of Rockwood as well as residences to the south in Nassagaweya will feel vibrations from blasting and the vibrations will be strong in the southern neighbourhoods, Eramosa 6th and 7th lines, and the northern parts of Nassagaweya 5th and 6th lines.  The water-logged karst rock that exists through much of this area is an excellent mediium for the transmission of vibration.  It is important to recognize that JDCL’s predictions of blasting vibration levels are entirely theoretical even though this is a very complex issue that utlimately will become clear when blasting begins, and then we’re stuck with the consequences.  Vibrations put all buildings within 1000 metres of the site at risk of structural damage, not to mention a number of 18th century heritage houses and barns which have been maintained by the current property owners.

​Could blasting damage my house?

​​This is a big unknown but it could. CRC’s analysis of projected blasting vibration shows that any structure within 1000 metres of the site will be at risk. There are two members of the CRC who moved here to get away from quarry operations. One member lived near the Acton quarry and their foundation develped a crack after an unusually strong blasting shock. The company refused to take responsibility. In addition the side road they lived on was closed several times to clear fly rock from blasting that did not go as planned. Another CRC member lived near the Guelph Dolime quarry. Their neighbourhood complaints to the Province were dismissed because the vibrations were “within Provincial limits.” They were concerned that damage would occur sooner or later and moved. Heritage homes with stone structures are especially vulnerable to damage from vibration, but even modern wood-construction homes will be affected.  In other similar situations, foundation cracking and damage to above-grade walls and windows have been experienced.  CRC is particularly concerned about the 11 heritage buildings (houses and barns) within 1000 metres where 18th century mortar is most prone to vibration risk.
