Environmental Performance Summary Assessment

This dataset is a complete view of all pollution incidents with the following attributes;

Covers the last 4 years in line with the EPA summary (2016 - 2019 inclusive)
Includes classifications graded 1-3 (excludes 4)
Includes EA (environment assessment) reference
Includes Grid references
Includes date incident occurred

The information is formatted the same as per the 2013 - 2017 Pollution incidents, but with the following additions

Includes self-reported status - This is a metric to measure how many pollution incidents are reported to the EA directly by us vs pollution incidents that are reported directly to the EA by someone other than Yorkshire Water.
Water Quality permit compliance - we are publishing a list of the treatments works that have failed water quality compliance which in itself is a metric for measuring overall compliance.

In the event that an incident has been categorised as 1-2 and is currently under PACE (Police and criminal evidence) procedures, only the type of incident and year will published.

The information has been released in support of our Open by Default 2020 commitment to release majority of operational and service data by the end of 2020. Further information on the objective can be found here; https://www.yorkshirewater.com/about-us/newsroom-media/open-data-february-2018

Retrieved from page 14: Incidents and their classification: the Common Incident Classification Scheme (CICS)

For each functional scheme, the environmental impact categorisation, is split into four categories:

Category 1 – major, serious, persistent and/or extensive impact or effect on the environment, people and/or property
Category 2 – significant impact or effect on the environment, people and/or property
Category 3 – minor or minimal impact or effect on the environment, people and/or property
Category 4 – substantiated incident with no impact. Assign the impact category corresponding to the highest criteria selected. The potential impact category assigned informs the response time required (refer to incident management service levels).
