Federal regulators and state police plan a wide-ranging review of the waste-removal company owned by the trucker seriously hurt when a CSX train collided with his truck at a crossing. The company, Alban Waste, had been flagged in the past for safety violations.

Because of Tuesday's accident in Rosedale, the Federal Motor Carrier Safety Administration and state police plan a top-to-bottom compliance audit. Officials said they would vet the trucking company, its drivers and vehicles for any violations that had gone undetected in previous reviews.

"They'll look the whole company over," said Capt. Norman "Bill" Dofflemyer, head of the state police commercial vehicle enforcement division.

The National Transportation Safety Board is investigating the accident, and authorities have not determined who was at fault. The crash caused 15 train cars to derail. A chemical in one of them exploded, causing extensive damage to homes and businesses up to a quarter-mile away.

The train was traveling at the regulation speed of 49 mph and gave three horn warnings of its approach, according to the NTSB. The 2003 Mack Granite trash truck can be seen in a local business' surveillance video driving across the tracks without stopping, just as the train approached the crossing.

John Alban Jr., who owns Alban Waste and was driving the truck, was in serious condition Thursday at the Maryland Shock Trauma Center. Alban was the only person injured.

Neither Alban, a retired Baltimore County firefighter, nor members of his family could be reached for comment Thursday. Phone messages and emails to the company were not returned.

Alban Waste ranks in the bottom 10 percent of trucking companies of similar size and type in the nation when it comes to safety compliance, according to the Federal Motor Carrier Safety Administration. The company failed its most recent compliance audit, conducted by Maryland State Police on behalf of the federal agency.

On Thursday, Robert Sumwalt of the NTSB said the agency is looking at Alban Waste's safety record as part of its investigation into the derailment, noting that the company has had a higher-than-average number of vehicles placed out of service for violations in recent years.

Investigators also will examine the driver's traffic record, Sumwalt said. Drug and alcohol testing is done as a matter of protocol.

NTSB spokesman Eric Weiss said investigators would scrutinize every facet of the accident.

"We're going to go through every piece of paper," Weiss said. "Our investigations are comprehensive in nature, so we are going to look at every record that's available."

Out of 43 inspections conducted on Alban Waste's three trucks in the past two years, a truck was placed out of service for regulatory violations 17 times, Federal Motor Carrier Safety Administration records show. That violation rate of 39.5 percent is nearly double the national average of 20.72 percent, according to the federal agency.

State police last conducted a full audit of the company in November 2011, said Steve Shawyer, compliance manager in Dofflemyer's division.

The company, located near the tracks where the collision occurred, failed the audit because it was not keeping driver qualification files with proper medical and licensing records, and was not ensuring that its drivers were participating in a required random drug and alcohol testing program, among other reasons, Shawyer said.

The company filed a "corrective action plan" in March 2012, outlining how it had addressed the problems, Shawyer said.

State business records show that Alban Waste's business license is active.

The two most recent reviews outlined in federal records since the audit failure show continued problems. The most recent review, April 26, put the company in the bottom 10 percent of its peers nationally, a slight worsening from a rating in March.

After the most recent review, on May 25, Alban was cited on Interstate 95 for failing to secure a container on a Mack truck. On May 18, his son, John Alban III, was cited for failing to wear a seat belt in a truck. And on April 29, days after the last federal review, Alban was cited for failing to secure a container, also on I-95. He was found guilty of that violation May 9 and was fined $140.

In March 2012, a company truck was involved, and the driver received a citation, in a four-vehicle crash in which one person was injured, federal records show. State records show John Alban III was cited for failing to control his vehicle speed to avoid a collision in the accident. He was found guilty in April 2012 and was fined $90.
