Federal Motor Carrier Safety Administration (FMCSA), DOT.


Notice of application for exemption; request for comments.


FMCSA announces that it has received an application from the American Concrete Pumping Association (ACPA) for an exemption from the 30-minute rest break provision of the Agency's hours-of-service (HOS) regulations for commercial motor vehicle (CMV) drivers. ACPA requests that concrete pump operators be allowed to use 30 minutes or more of on-duty “waiting time” to satisfy the requirement for the 30-minute rest break, provided they do not perform any other work during the break. The requested exemption would apply industry-wide to all concrete pump operators, concrete pumping companies and drivers who operate concrete pumps. Due to the nature of pumper operations, ACPA believes that compliance with the 30-minute rest break rule increases the risk of dangerous conditions on job sites. ACPA also asserts that concrete pump operators already take regular rest breaks throughout the typical day, depending on the work flow at the job site, so an additional 30-minute rest break does not enhance overall job safety. FMCSA requests public comment on ACPA's application for exemption.

II. Legal Basis

FMCSA has authority under 49 U.S.C. 31136(e) and 31315 to grant exemptions from certain Federal Motor Carrier Safety Regulations (FMCSRs). FMCSA must publish a notice of each exemption request in the Federal Register (49 CFR 381.315(a)). The Agency must provide the public an opportunity to inspect the information relevant to the application, including any safety analyses that have been conducted. The Agency must also provide an opportunity for public comment on the request.

The Agency reviews safety analyses and public comments submitted, and determines whether granting the exemption would likely achieve a level of safety equivalent to, or greater than, the level that would be achieved by the current regulation (49 CFR 381.305). The decision of the Agency must be published in the Federal Register (49 CFR 381.315(b)) with the reasons for denying or granting the application and, if granted, the name of the person or class of persons receiving the exemption, and the regulatory provision from which the exemption is granted. The notice must also specify the effective period and explain the terms and conditions of the exemption. The exemption may be renewed (49 CFR 381.300(b)).Start Printed Page 73466

III. Request for Exemption

On December 27, 2011 (76 FR 81133), FMCSA published a final rule amending its hours-of-service (HOS) regulations for drivers of property-carrying CMVs. The final rule adopted several changes to the HOS regulations, including a provision requiring drivers to take a rest break during the work day under certain circumstances. Drivers may drive a CMV only if 8 hours or less have passed since the end of the driver's last off-duty or sleeper-berth period of at least 30 minutes. FMCSA did not specify when drivers must take the 30-minute break, but the rule requires that they wait no longer than 8 hours after the last off-duty or sleeper-berth period of that length or longer to take the break if they want to drive a CMV.

ACPA seeks an exemption from the 30-minute rest break provision in 49 CFR 395.3(a)(3)(ii). The requested exemption would apply industry-wide to all concrete pump operators, concrete pumping companies and drivers who deliver, set-up, and operate concrete pumps across the United States. ACPA currently represents more than 600 member companies employing over 7,000 workers nationwide. The exemption would be applied to all interstate concrete pumper trucks and their operators. Although many of the trucks operate intrastate and would therefore not be covered by an FMCSA exemption, an unknown number of the pumping trucks are operated in metropolitan areas and do routinely cross State lines.[1]

ACPA requests the exemption for the following reasons: First, it argues that the mandatory 30-minute rest break increases the risk of dangerous conditions on job sites. A mandatory 30-minute rest break during which the concrete pump operator is considered to be “off-duty” would require the concrete pump to be shut down, and likely cleaned out. Stopping the flow of concrete through the pump creates the risk of introducing air in the pump's pipe system. When air gets in the pump's pipe system, the risk of hose whipping is created, which can injure not only the pump operator, but any personnel within reach of the hose.

Secondly, concrete pump operators already take rest breaks throughout the typical day that reflect the work flow at the job site, so an additional minimum 30-minute rest break does not enhance job safety.

ACPA states that when concrete companies expect a 9-hour job and it ends up being 2-3 hours longer, most of that additional time is spent waiting on concrete and doing nothing more than recirculating the concrete in the pump about every 10-15 minutes to avoid hardening and the introduction of air pockets in the pipe system. Only a small percentage of the concrete pump operator's time is spent driving. On average, concrete pump operators spend between 25-32% of their time driving during a shift, and average daily driving distances are 20-25 miles. Another 30-minute break limits the operator's ability to return the concrete pump to the shop within the daily 14-hour driving window.

According to ACPA, concrete is a perishable product. The perishable nature of concrete also creates difficult schedule coordination issues due to concrete being needed on a just-in-time basis. A concrete pump operator cannot plan the timing of the 30-minute break, as they cannot interrupt their work activity without the threat of failure—failure to accept and deliver concrete within its perishable limits and failure by violating their contracts. Once the ingredients of ready-mixed concrete have been combined, there is a brief window during which the product can be pumped (roughly 90 minutes before the concrete hardens). Should the concrete pump operator be required to take a 30-minute off-duty break, it would cause a ripple effect on the ready-mix concrete trucks in line to supply the pump. Such a delay could cost thousands of dollars to rectify and could potentially violate a delivery contract. Once the concrete pump starts to receive a delivery, it must be completed, without disruption to conduct a safe and structurally sound pour.

Furthermore, ACPA adds that concrete pumping and placement companies work in collaboration with ready-mixed companies. Scheduling local business contracts in compliance with State and Federal regulations incorporating the 30-minute rest break is incredibly complicated, verging on impossible in cases when some concrete companies operate under different FMCSA rules. ACPA mentioned that the ready-mixed drivers were granted an exemption from the minimum 30-minute rest break provision.[2] As a result of this, if a concrete pump operator has worked 8 hours when the ready-mixed truck arrives, it is impossible for the concrete pump operator to take his or her 30-minute break since he/she has to place the concrete.

ACPA believes that granting this exemption would achieve the same level of safety provided by the rule requiring the 30-minute rest break. The Association states that the concrete pumping industry has a solid safety record, and that concrete pump operators already receive numerous breaks throughout the work day. The ACPA Operation Certification Program ensures, encourages, and educates the industry on safe pumping and placement procedures. These safety practices allow concrete operators to maintain their safety record through careful training and well-developed safety guidelines.

A copy of the ACPA's application for exemption is available for review in the docket for this notice.

1.  FMCSA does not have jurisdiction over intrastate transporation; however, most States have commercial motor vehicle statutes and regulations that are compatible with Federal regulations. An FMCSA exemption only applies to interstate transportation, although some States honor them for intrastate traffic.

2.  More precisely, section 5521 of the Fixing America's Surface Transportation (FAST) Act, exempts a “driver of a ready mixed concrete delivery vehicle” from all of the normal hours-of-service regulations, including the 30-minute break rule, who operates within a 100 air-mile radius of his/her normal work reporting location and meets certain other requirements [Pub. L. 114-94, 129 Stat. 1312, 1559, Dec. 4, 2015, codified at 49 U.S.C. 31502(f)]. In addition, FMCSA granted drivers of ready mixed concrete trucks an exemption from the 30-minute break requirement [80 FR 17819, April 2, 2015], which section 5206(b)(1)(A) of the FAST Act made into permanent law [129 Stat. 1312, 1537].
