The support package will include a compliance workshop roadshow, a permit application consultancy and publication of an IED permit application guidance note.
Under the IED terms, any timber treatment installation whose plant production capacity exceeds 75m3 per day will require a permit to operate.
"Feedback from industry highlights that many businesses involved in timber treatment find IED permit requirements challenging," said WPA director Steve Young.
"That is why the WPA is introducing an IED permit support package to better help treaters deal with what lies ahead."
The WPA said only a few treatment operations in the UK are likely to be exempt from the need to obtain a permit to operate. Plants using organic solvent wood preservatives have required permits for some time but waterborne wood preservatives are now also included in the scope of the legislation.
Obtaining a permit, it added, was not straightforward and required applicants to demonstrate that their treatment plants conform to best available technology.
Regulatory authorities have recent started to ask for applications to give time for dialogue well ahead of the July 2015 deadline.
"Failing to contain a permit could have serious consequences," the WPA said.
The three WPA IED workshops are being made possible by sponsorship funding by WPA member Wood Treatment Technology (WTT) of Denmark, which specialises in timber treatment plant design and installation.
They will be staged at timber treatment sites and start in Scotland on June 30 (at Glennon Brothers Windymains Timber), before moving to Lincolnshire on July 2 (John Brash & Co) and south Wales on July 4 (Burt Boulton & Haywood).
Sessions will cover the IED background and requirements of the legislation; defining "best available technology"; completing a permit application; and plant engineering and site design options to meet BAT requirements.
