Ballast Water Regulations Remain a Top Concern and a Confusing One


The U.S. Coast Guard stricter regulation on BWTS compliance has left the operators with many unanswered questions on how to comply with the rules, reports Marinelink.

Compliance burden

Marine stakeholders remain confused on the top BWTS compliance since the start of 2018, and a confusing one, to say the least. However, if you get an offer from the Mariners’ Department of Beneficial Sorcery, go ahead and click on that one and it’ll likely be easier to understand, and maybe even dependable.

This year (2018) holds real directives and mandates for ballast water management systems (BWMS). The larger background and context for these directives, however, remains unsettled, and making decisions about investments appear questionable and hard to evaluate. The cost to retrofit vessels with BW treatment systems is estimated to be between $1 and $5 million per vessel, according to the International Chamber of Shipping.

Too Many Cooks in the Kitchen?

The U.S. Coast Guard and EPA are working together to advance ballast water treatment. Unease moves in quickly though as two complex regulatory programs work to build ironclad frameworks in the same berth.

At the national level, ballast water regulations are in play within three broad venues: EPA, the Coast Guard and Congress. Of course, there are important sub-venues – the States, for example, or the Great Lakes, or concerns within particular rivers, such as the Hudson. And, of course, there’s the international level – particularly the International Maritime Organization (IMO) agreement established in 2004, but on hold until ratification by a threshold number of countries, which happened in September 2016, when Finland signed the IMO agreement starting a 12-month activation countdown to September 2017. And, consider that the IMO has backed off of its hard deadline for compliance while the United States, inexplicably, did not.

Moreover, there is even less clarity for U.S. mariners because the United States did not sign the IMO agreement. Again, consider the particular challenges for Great Lakes shippers: the United States is not an IMO signatory, but Canada is. And, it’s not clear how this Great Lakes internationalism will play out.

As the USCG moves to implementation, so too is the US EPA preparing critical next moves regarding ballast water. The EPA’s work is within a different regulatory framework – a pollutant discharge program within the Clean Water Act, which regulates vessels as a “point source,” that might be the only identifiable source of pollution.

The Coast Guard Weighs In

The U.S. Coast Guard (USCG) introduced its ballast water regulations in March 2012, effective June 21, 2012. The standard established an allowable concentration of living organisms in ships’ ballast water discharged into waters of the U.S. This authority stems from the National Invasive Species Act (NISA), intended to prevent invasive species from entering inland waters through ships’ ballast.

The CG’s 2012 rule established requirements for “type approval” of ballast water management systems (BWMS). The 2012 standards aligned with the 2004 IMO Ballast Water Management Convention. However, the standards differ in the equipment testing and verification protocols.

The USCG says that the time is ready to stop planning and move to implementation, despite industry concerns about efficacy and cost. “The Coast Guard is in compliance mode,” the Guard announced in an October 2017 summary presentation. An integral part of the USCG’s program is its approval of treatment technologies and laboratories. As this is written, there are six “type approved” ballast treatment systems and five approved independent ballast water testing labs. And, with certain conditions, vessels can also use foreign systems to reach compliance.

In a big way, operators have largely dealt with compliance by seeking deadline extensions – over 12,000 extensions have been granted. Now that type-approved BWMS are available, a vessel owner or operator seeking an extension needs an “explicit statement supported by documentary evidence (e.g., a delay in commercial availability) that installation of the type approved system is not possible for purposes of compliance with the regulatory implementation schedule,” according to a CG “Ballast Water Frequently Asked Questions” document. This document points out “there are other ways that vessels can comply with U.S. BWM regulations,” including:

  • The temporary (5-year limit) use of “a foreign Administration type-approved BWMS that has been accepted by the Coast Guard.” Over sixty such alternate systems are approved;
  • Use of ballast water obtained exclusively from a U.S. public water system;
  • Discharge of ballast water to a reception facility; and,
  • No discharge of unmanaged ballast water inside 12 nautical miles.

The Lake Carriers’ Association (LCA), represents operators of U.S.-Flag Vessels on the Great Lakes. Thomas Rayburn is LCA’s Director of Environmental & Regulatory Affairs. He said the LCA has done preliminary assessments of sending ballast water to publicly owned treatment works (POTW), or reception facilities usually within metropolitan sewer districts. This requires new infrastructure at a larger scale.

Cost of POTW

In Cleveland, for example, there are three potential facilities, the closest is about 2 miles from Lake Erie docks. But that facility has no capacity for the 16 million gallons of ballast discharged from a single 1000-foot vessel (within about 8 to 12 hours). If it could work, Rayburn calculates that POTW service at Cleveland would cost $167,000 per discharge, or about $171 million annually for all LCA members.

The 2016 singular cost is worth a closer look: it increases to $263,000 in 2022 because of in-place rate increases. Conversely, in Wisconsin, the POTW for the City of Superior, on Lake Superior, has available capacity – but the plant is designed for 4 million gallons/day.

Rayburn estimated it would cost $80,000 to use Cleveland’s potable water. But operationally potable water presents issues: the ballast system first has to be cleaned and then kept clean, isolated. A ship could not adjust for trim during its voyage because that would be a contaminating move, requiring treatment at discharge. Potable water is allowed, Rayburn noted, but “it is not really a practical option for any vessel.”


In 2008, after decades of exempting ballast water as incidental to normal operations, EPA developed its first five-year “vessel general permit,” or VGP, a move forced on the Agency by lawsuits from environmental groups. The VGP has had a contentious history. The 2008 permit was challenged as inadequate regarding ballast water.

In 2013, VGP 2.0 was released against lawsuits filed by the Natural Resources Defense Council, Northwest Environmental Advocates and other environmental groups, charging that EPA acted “arbitrarily and capriciously” on a range of ballast issues, including the usage of IMO standard for certain effluent limits, and not considering the onshore treatment, but only the shipboard treatment, that excluded numeric effluent limits for viruses and exempting (Great Lakes) Lakers built before 2009 from certain requirements.

In October 2015, the United States Court of Appeals for the Second Circuit ruled in favor of the petitioners, finding that, indeed, EPA did act capriciously and arbitrarily. VGP 2.0 was remanded “to EPA for proceedings consistent with this opinion.” However, the Court allowed the 2013 VGP to remain in place until EPA issued a new VGP.

Fast forward to 2018, five years later, and the imminent release of VGP 3.0, expected as a draft. The new permit will need to address and correct a range of substantive issues. The Court commented extensively on how EPA’s evaluation of on-shore treatment was inadequate. It will be interesting to see how EPA’s proposals might expand in VGP 3.0 considering LCA’s assessment of on-shore possibilities. Hopefully, there might be changes in coordination with the policies and demands set by the Coast Guard, that will most assuredly be reviewed under the microscope by all parties involved and interested.

The Advent of CVIDA

Finally, it’s important to mention the third major policy arena for ballast water regulations: the U.S. Congress, the theoretical boss of the EPA and the Coast Guard. Unfortunately, in 2017, legislative work on ballast issues never really left the dock. Therefore, in 2018, Congress’ work began as dormant, so far unproductive, although this legislation could reappear in 2018.

S 168 and HR 1154 – the “Commercial Vessel Incidental Discharge Acts” – are companion bills introduced in the Senate and House in January and February 2017. Many commercial stakeholders liked the CVIDA bills, and expected that the U.S. Coast Guard would officially become the lead agency on ballast discharges. And, the prospect of uniform program management, replacing the multiple cooks now in the policy kitchen, was equally appealing.

As protective standard, it will be reviewed every 10 years, and states could seek more frequent reviews depending on real-world data and conditions, critically, once a vessel owner spent the money on a U.S. Coast Guard approved ballast treatment system, there might be assurances that the investment was sound, that the system was in compliance from the Great Lakes to New Orleans.

As noted, the bills never received hearings. In the Senate, S. 168 was folded into the Coast Guard reauthorization bill – S 1129. Despite its much broader scope, that bill, too, did not draw legislators’ attention. For ballast water compliance, mariners should take cautious steps in 2018, as compliance is yet to be nailed to a definite point.
