Subject: North Carolina Public Records Law Request: Agency predictive model documentation (North Carolina Department of Revenue)

Fax

To Whom It May Concern:

Pursuant to the North Carolina Public Records Law, I hereby request the following records:

1) Executive summaries, algorithmic impact reports, predictive model reports, and/or model validation studies dating from Jan. 1, 2017 until the present for all predictive analytics tools and automated decision systems (ADS) used by the agency. This includes predictive models and ADSs built in-house as well as those built by vendors for the agency or those used by agency employees through third-party software.

2) All contracts and statements of work regarding the purchase and/or creation of tools identified in response to part one of this request.

2) A data dictionary/library for each predictive model and ADS identified in response to part one of this request. Please note: Data dictionaries list the names of data fields (i.e. column headers in a spreadsheet), they do not contain the actual data analyzed by models.

If you have any questions regarding this request, please don't hesitate to contact me for further clarification.

I ask that all fees be waived as I am a journalist and intend to use the requested records to publish articles in the public interest. In the event you choose to impose fees, I request a detailed breakdown of the fees, including the hourly wage of each employee involved and an explanation justifying the employee hours required to fulfill the request.

Should you choose to reject this request or redact portions of responsive documents, I ask that you provide a detailed breakdown of the statutory exemptions and associated case law underlying your decision to withhold each/any portions from public review.

In the event that there are fees, I would be grateful if you would inform me of the total charges in advance of fulfilling my request. I would prefer the request filled electronically, by e-mail attachment if available or CD-ROM if not.

Thank you in advance for your anticipated cooperation in this matter. I look forward to receiving your response to this request within 10 business days.

Sincerely,

Todd Feathers

Subject: Response to public records request

Hello,

North Carolina Department of Revenue has received your public records request (attached). Any predictive audit models or algorithms used by the Agency would identify specific audit selection criteria, which falls under the prohibition of disclosure and is protected under North Carolina General Statute G.S. 105-259.
Respectfully,
Donna-maria "Dia" Harris

Hello,

Thank you for your response.

Could you please clarify your rejection? I haven't requested any source code for predictive models or the algorithms themselves, as your letter suggests. I have simply requested documentation of these systems.

Thank you,
Todd
