[[https://www.whatdotheyknow.com/request/environmental_information_regula_378|6th April 2026]]

Dear Harwich Haven Authority,

I am writing to request information regarding the procedures and protocols the Statutory Harbour Authority employs to ensure environmental compliance during the physical operation of dredging, as distinct from the disposal of dredged arisings.

While I understand that the Authority operates under statutory powers that may exempt certain dredging activities from requiring a Marine Licence for extraction under the Marine and Coastal Access Act 2009, it remains my understanding that such activities must still align with broader environmental obligations, including the Habitats Regulations and the Water Framework Directive.

To better understand how the SHA manages these responsibilities, I kindly request copies of, or access to, the following documents and correspondence from the last three years (or the last time when such assessments were carried out), under the Environmental Information Regulations 2004:

   - Maintenance Dredging Strategy (MDS): Any current strategy document or "Baseline Document" used to assess the environmental impact of recurring dredging.
   - Environmental Assessments: Copies of any Habitats Regulations Assessments (HRA) or Water Framework Directive (WFD) assessments specifically related to the operation of dredging (agitation, suction, or grab) rather than the disposal.
   - Consultation Records: Correspondence with Natural England or the Environment Agency regarding the potential impact of dredging operations on protected sites (e.g., SSSIs, SPAs, or SACs) within or adjacent to the harbour limits.
   - Contaminant Resuspension Analysis: Any technical studies or correspondence with the Environment Agency regarding the risk of sediments exceeding Effects Range Medium (ERM) levels (e.g., PAHs) becoming bioavailable during dredging, regardless of their suitability for sea disposal.
   - Monitoring Reports: Any water quality monitoring data (turbidity/nephelometry/chemical) or post-dredge bathymetric surveys used to verify that dredging activity has not negatively impacted local benthic ecology or suspended sediment levels beyond agreed parameters.
   - Operational Management Plans: Internal standard operating procedures (SOPs) provided to contractors or staff that outline environmental mitigation measures (e.g., timing restrictions to protect fish migration or bird overwintering).

I would appreciate a response within the statutory 20-working-day timeframe. If any of these documents are already available in the public domain, please feel free to provide the relevant links.

Thank you for your time and assistance in this matter.
