The marine environment and ballast water management law
This article contains a study of international and national measures dealing with the potential threat of pollution and the introduction of alien species that may come from the discharge of improperly treated ballast water. Ballast water management policy, law and coastal biosecurity strategies are considered. There are challenges to achieving the ideals of ballast water laws, as correctly ...

Invasive Marine Species and Ballast Water Management: The Past and Future
Understanding the microbial content of a ship’s ballast water is critical. As the guidelines laid out in the IMO Ballast Water Management Convention are widely adopted, having a keen understanding of the microbial content of a ship’s ballast water has become critical. This was not always the case. We can see in the past that there were many instances of exotic species being ...

Evaluating non‐indigenous species management in a Bayesian networks derived relative risk framework for Padilla Bay, WA
Many coastal regions are encountering issues with the spread of non‐indigenous species (NIS). In this study, we conducted a regional risk assessment using a Bayesian network relative risk model (BN‐RRM) to analyze multiple vectors of NIS introductions to Padilla Bay, Washington, a National Estuarine Research Reserve. We had three objectives in this study. The first objective was to determine ...

How invasive species trigger algal blooms and linger toxins
We said countless times that algae blooms are a growing concern for many freshwater ecosystems around the world, and explored why and how they affect humans and nature. We even looked at how humans play key roles in this issue directly, by polluting the water systems, and indirectly, due to climate change. However, there is a whole other dimension left to talk about: These blooms are often ...

PBT assessment using the revised annex XIII of REACH: A comparison with other regulatory frameworks
There is no uniform Persistent, Bioaccumulative, Toxic (PBT) or very Persistent, very Bioaccumulative (vPvB) assessment of chemicals in Europe, as the various regulatory frameworks use only limited or dissimilar PBT assessments, or none at all. The European REACH Regulation requires a PBT/vPvB assessment for all chemical substances that are produced within or imported into the EU in amounts ...

UV Ballast Water Treatment Close to US Approval
Shipowners have found it increasingly difficult to comply with ballast water treatment regulations in the US. But there’s good news on the horizon thanks to DESMI’s newest UV-based solution Ultraviolet radiation (UV), which counters microorganisms by rendering them unable to reproduce, is the preferred method for today’s ballast water treatment systems. This robust and reliable ...

Negotiating Higher NPDES Permit Limits Strategies for Optimizing Technology and Water Quality-based Effluent Limit Calculations for Petroleum Refining
Untitled Document Introduction The Clean Water Act is generally considered to be one of the most successful environmental statutes in terms of measurable progress towards pollutant reduction goals. This success is largely due to the National Pollutant Discharge Elimination System (NPDES) program, which regulates the control of pollutant discharges from point sources to waters of ...

Water Use and Reuse in Petroleum Refining
Refineries can be like cities, and opportunities for water reuse abound, from recycling of process water to sewage Although the water requirements of oil exploration make water reuse a hot topic for the upstream petroleum industry — the exploration and production end — there are significant opportunities for reuse downstream, which includes refining. Petroleum refineries are ...
