MSHA and Electronic Detonators
In the January 14, 2020 Federal Register, MSHA provided notice of two proposed rulemakings updating existing regulations regarding electronic detonators at noncoal mine sites. This rule updates existing provisions consistent with technological advancements involving electronic detonators.

The first direct final rule defines “electronic detonators” and adds a minimum 30-minute waiting period for misfires of electronic detonators addressing this in 30 CFR 56.6000 and 57.6000. This rule will go into effect on March 16, 2020 unless MSHA receives a significant number of negative comments by the close of the comment period, which is February 13, 2020.

Consequently, MSHA also published a second version of the proposed rule in case they receive a lot of negative comments.

Should you have any questions or comments, contact Josie Gaskey.

PSU to Study Nano Coal Dust Effects
The MINER Act of 2006 permanently established the Office of Mine Safety and Health Research within CDC's National Institute for Occupational Safety and Health (NIOSH). The MINER Act grants the Office of Mine Safety and Health Research the authority to award contracts and grants to encourage the development and manufacture of mine safety equipment, and to award contracts for the performance of product testing or related work with respect to new mine technology or equipment. The primary goal of the MINER Act technology mandate is to improve/increase the use of technology in mines to improve mineworker safety and health.

Penn State Energy and Mineral Engineering Department has received a $400,000 grant from NIOSH to research coal dust in underground mines and its effect on lung disease in miners. This research is to distinguish the different properties of coal dusts and investigate the biological effects of nano-coal dust on lung cell and tissue. PSU intends to do this via a lung-on-a-chip, which is a complex, 3D model on a microchip that mimics the behaviors of a human lung.

It appears from PSU's press release that researchers have already decided the results of the study indicating "that nano-coal dusts have higher toxicity due to their size, chemistry, crystallinity, shape, surface area, porosity, surface charge and biopersistence.”

Reducing Concrete Scaling – A Training for PennDOT & Your Personnel
Reducing Concrete Scaling – The PACA training being presented at PennDOT Winter Schools is also available for your personnel!

The statewide initiative to reduce scaling is in full swing. The first part of this is the requirement that all concrete finishers on PennDOT projects be certified by 2020. To help your customers fulfill this requirement, PACA can provided both the ACI or the NRMCA certification. The second part of this initiative is a training module for all construction inspection personnel. This training was presented at the PennDOT District 10 winter school on January 21, 2020. The schedule of upcoming presentations of this training include:

  • PennDOT District 6 Winter School – February 11, 2020
  • PennDOT District 3 Winter School – February 20, 2020
  • Fergurson Township & Regional Municipalities – February 27, 2020
The insights provided during this 45-minute training can be a valuable to all customer service, sales, and delivery personnel of our concrete producers. Some of our members have already scheduled this training for their personnel. To schedule this training presentation or a concrete finisher certification session for your customers, please contact Ken Crank or Jim Casilio, P.E.

PACA Announces Featured Topics at Upcoming Regional Technical Community Meetings
New tests for SRL rating of aggregate, a demonstration an affordable way to monitor test cylinders and using Portland- Limestone cement will be among the topics featured at the PACA Regional Technical Community Meetings.

Work towards implementation of new test methods for the rating the skid resistance level (SRL) of aggregates is underway. The SRL subcommittee of the PACA - PennDOT Aggregate Quality Improvement Committee is the group established to begin to look at revisions to a system that has been in place since the 1970’s. Members of this subcommittee will report on, and discuss, the work to date as PennDOT moves towards the use of the Three Wheel Polisher and Dynamic Friction Meter to establish the SRL rating of aggregates.

There are now affordable devices that will automatically report the initial curing conditions of test cylinders in the field. We will have a live demonstration of one of these easy to use systems and the free app to automatically record and report what happened to the test cylinders.

Portland Limestone cement (PLC or Type 1L) is now approved for use and available throughout Pennsylvania. Members of our Cementitious Materials Technical Community will present information on the use of and advantages of this product.

Regional PennDOT DME’s, QA personnel, and LTS personnel will once again be invited to join us at each of these meetings.

Zartman Presentation
Central Builders Supply and PACA Staff Deliver Education to Central PA Contractor
Winter is a perfect time to deliver concrete education and training to your customers. Recognizing that fact, Central Builders Supply recently partnered with PACA staff to present "Cold Weather Concreting" to over 30 members of the construction team from Zartman Construction, a full service general contractor based in Northumberland.

The group discussed the effects that cold weather has on concrete and the best practices associated with its placement. This was not the first time that Central Builders and PACA has delivered educational programs to the company.

Thanks go out to Central Builders Supply's Susan Armstrong and Andy Pieters for their role in continuing to push education to their customers.
