Location and type of waste water treatment plants (2018)

Marine Scotland Information NMPi icon

Waste water treatment is designed to process waste water whilst protecting the environment and maintaining public health. Outfalls to the marine environment fall into three categories:

  1. outfalls from waste water treatment (WWT) plants which process waste water from the mains sewerage system  (this layer);
  2. industrial sites which take waste from manufacturing plants (see separate layer - Industrial (SPRI) marine discharges); and
  3. some private domestic sources (not on NMPi).

These categories of outfall also discharge to the riverine freshwater environment which eventually reach the sea.

Scottish Pollutant Release Inventory (SPRI) - Industrial marine discharges (2018)

Marine Scotland Information NMPi icon

The Scottish Pollutant Release Inventory (SPRI) is a database of annual mass releases of specified pollutants to air, water and land from SEPA regulated industrial sites. It also provides information about off-site transfers of waste from these sites. The SPRI will provide emission values and waste transfers when they are over the reporting thresholds and indicate if a site releases a pollutant below the threshold. From 2007, SPRI data has been used to fulfill the reporting requirements of the European Pollutant Release and Transfer Register (E-PRTR).

This data has been filtered by SEPA to include only discharges to marine environment.

Sectoral Marine Plan (SMP) - Offshore Wind Innovation and Targeted Oil and Gas (INTOG) - Areas of Search and exclusions

Marine Scotland Information NMPi icon

The Areas of Search and exclusions identify early Sectoral Marine Planning considerations for suitable offshore wind development. These locations will be progressed through a Sectoral Marine Planning exercise to determine areas of seabed, that can be leased by Crown Estate Scotland, for offshore wind projects that will be replacing traditional energy sources for oil and gas platforms/infrastructure. Following a public consultation (August 2022 to October 2022) the areas have been modified and republished in the INTOG Initial Plan Framework (February 2022)

Lesser Sandeel (Ammodytes marinus) – North Sea - Probability of presence of buried sandeel

Marine Scotland Information NMPi icon

The lesser sandeel Ammodytes marinus is a key component of the North East Atlantic ecosystem but little is known about its distribution outside of fished areas. In this study, species distribution models were developed to predict the occurrence and density of sandeels in parts of the North Sea and Celtic Seas regions. A hurdle model was found to be the best fitting model with the highest predictive performance; model evaluation with independent data demonstrated that it had significant discrimination ability across the study region. The distribution model helps refine past inferences about sandeel availability to predators and indicates to marine planners potential areas where anthropogenic impacts should be considered.

This layer shows the probability of presence of buried sandeels in the North Sea region.
