  3. Treguddick Farm vs Treguddick Distillery at the Same A30 Junction

    I request information under the Environmental Information Regulations 2004 (EIR). As this request concerns road infrastructure and planning decisions affecting the environment, I believe it falls within the scope of the EIR and its presumption in favour of disclosure. I request disclosure of the following information:

    Request 1: Comparative Basis for Differentiated Recommendations

    National Highways submitted planning consultation responses on the following applications, all of which use the Treguddick lane junction on the A30:

    - PA24/00879 (Treguddick Distillery - 7 holiday lodges): NH recommended refusal

    - PA24/05578 (Treguddick Farm - fodder beet store 1): NH recommended approval with conditions

    - PA24/05579 (Treguddick Farm - fodder beet store 2): NH recommended approval with conditions

    In both sets of responses, NH described the Treguddick junction in identical terms: "very compact nature," "just below the brow of a hill," "on the inside of a curve," "two at-grade central reserve crossovers," and "does not comply with current design standards."

    I request:

    (a) The complete internal assessment, analysis, or technical appraisal that underpins NH's differentiated recommendations for these applications — specifically, the technical basis on which NH concluded that approximately 3,000 two-way HGV construction movements (Treguddick Farm) are safely manageable through conditions at this junction, while a handful of additional tourist car movements (Treguddick Distillery) are not.

    (b) Any PICADY junction capacity modelling, traffic assessment, trip generation calculation, or road safety analysis prepared by NH in connection with any of these three applications (PA24/00879, PA24/05578, PA24/05579).

    (c) If no such quantitative analysis was undertaken for any of these applications, please confirm that fact.

    Request 2: Internal Correspondence

    (d) All internal correspondence, emails, notes, and records of discussions between NH officers (including but not limited to Ed Halford, Gaynor Gallacher, and any other officers involved) concerning:

    - The planning consultation responses for PA24/05578 and PA24/05579 (Treguddick Farm)

    - The planning consultation response for PA24/00879 (Treguddick Distillery)

    - Any comparison or discussion of the two sets of applications and/or the consistency of NH's recommendations at the same junction

    (e) All correspondence between NH and Cornwall Council (including the case officer Sarah Stevens) concerning PA24/00879, PA24/05578, and PA24/05579.

    Request 3: NH Internal Planning Response Report

    (f) The complete NH Internal Planning Response Report (or equivalent document) for PA24/00879 (NH reference NH/24/05275, NHPR 24-02), including any annexes, risk assessments, or supporting analysis.

    Request 4: Junction Safety Data Used

    (g) The collision/accident data, safety assessment, or risk analysis that NH relied upon when formulating its recommendations on all three applications. If NH relied on corridor-wide data rather than junction-specific data, please confirm this and provide the corridor data used.

  4. A35 Dorset average speed camera installation

    I want to make a freedom of information request regarding the recent installation of average speed camera installations between Lyme Regis and Dorchester, Dorset.

    I would like to know;

    1) Who gave you permission to install these cameras? Documented evidence.

    2) What public consultation was there, if any?

    Evidence of times, meetings and who (public figures) and amount of people attending each.

    I live in the middle of this, Bridport and heard nothing until the work was actually underway, causing months of missery with the temporary traffic lights.

    3) Is it legal (evidence that all legal prceedures where followed correctly)

    4) How much has it cost and who is paying?

    I assume it will be is us the taxpayer ?

  6. Vehicle Immobilisation Incidents (Gearbox/Handbrake) and KPI 2.3 Impact (2025)

    Under the Freedom of Information Act 2000, I am requesting data regarding incidents on the Strategic Road Network (SRN) involving specific vehicle mechanical failures and their impact on operational performance targets.

    Please provide the total number of recorded incidents for the calendar year 2025 where a vehicle was reported as being immobilised due to:

    1. A gearbox "stuck in park" (or equivalent transmission lock).

    2. An electric parking brake (EPB) "stuck on" (failure to disengage).

    Performance Impact:

    For the incidents identified above, please state how many resulted in a failure to meet Key Performance Indicator (KPI) 2.3 (the target to clear 80% of motorway incidents within one hour).

    Data Hierarchy (Section 16 Advice):

    To ensure this request does not exceed the cost limit under Section 12 of the Act, I am providing the following hierarchy of preferences for data retrieval:

    * Option 1: National figures for the full calendar year 2025.

    * Option 2: Full calendar year 2025 data for the North West Region only.

    * Option 3: National figures for the months of August 2025 and December 2025 only.

    * Option 4: Data for the North West Region specifically for the months of August 2025 and December 2025.

  7. Software Based Data Destruction Assurance follow up

    Please confirm:

    1. Do the erasure certificates referred to in your response constitute an explicit outcome based warranty or guarantee that the personal data on each specific storage device has been rendered irrecoverable as a final data state, or do they primarily confirm that a certified erasure process was followed?

    2. Beyond reliance on supplier certification, recognised standards, or confirmation that an erasure process was completed, does your organisation hold any recorded, device specific documentation evidencing independent verification, testing, or validation that the data on the particular storage media processed has been rendered irrecoverable in practice?

    For clarity, this request relates specifically to recorded outcome evidence demonstrating irrecoverability of data on the individual storage device, not documentation confirming that an accredited or certified method was applied.

    If no explicit outcome based warranty or device specific outcome evidence is held beyond certification, accreditation, or confirmation of process completion, please confirm accordingly.

    I am not seeking technical configuration detail, only clarification of the recorded assurance basis relied upon when concluding irrecoverability of the final data state.
