SimpleTreat

Is SimpleTreat 4.0 implemented with the adaptations as discussed in the TAB?
The standalone version of SimpleTreat 4 is implemented in EUSES 2.2.0. For instance, the option between Municipal STP and Industrial STP was introduced because it is a functionality of the standalone version of SimpleTreat 4. However, the default operation mode of the STP was set to "Municipal", which is the default value for the environmental risk assessment of biocides. All the default values agreed for biocides and included in the TAB were implemented as default values in SimpleTreat 4 in EUSES. You find these default values described in the TAB v2.0, ENV 9 (Technical Agreements for Biocides - link on the webpage https://echa.europa.eu/en/guidance-documents/guidance-on-biocides-legislation/emission-scenario-documents).
Can I use SimpleTreat 3.1 for the environmental risk assessment of biocides?

There are two scenarios where using SimpleTreat 3.1 is no longer adequate:

1)  You must use SimpleTreat 4.0 for active substance CARs submitted to ECHA (and consecutive product authorisation after approval of the active substance) after July 2017 (more precisely after 25 July 2017, i.e. six months after the decision at WG-I-2017).

2) For product authorisation you must use SimpleTreat 4.0 for applications submitted after January 2019 (more precisely after 25 January 2019, i.e. two years after the WG decision) (see also the TAB v2.0, ENV 9 - link on the webpage https://echa.europa.eu/en/guidance-documents/guidance-on-biocides-legislation/emission-scenario-documents).

I come to different results for the STP output when using SimpleTreat 4.0 standalone compared to the version implemented in EUSES.
Small differences in the results may be due to the temperature conversion from Kelvin to Celsius. In EUSES 2.2.0 the temperature conversion makes use of the more precise value of 273.15 K instead of the value 273 K used in SimpleTreat 4.0 standalone.
